2016-204 Old Cedar Avenue Trail/2016-101 PMP Old Cedar Avenue /2015-203 Old Cedar Trailhead
The Northern long-eared bat is a federally-listed threatened species that is found in Hennepin County.  During late spring and summer the bats roost and forage in upland forests. The road and trail project will require removal of trees within the project limits. In order to not adversely impact the Northern long-eared bat, all tree removal in wooded area (as opposed to yard trees which are usually considered an incidental take) must be removed prior to April 1.  City Maintenance crews will be removing trees within the City right-of-way and easements only as necessary along Old Cedar Avenue to ensure compliance with this regulation.

2010-201 Old Cedar Avenue Bridge Rehabilitation over Long Meadow Lake

One temporary horizontal truss has been installed at Span 4.  Work continues on the temporary system for Span 4, installing tower ties, and rods for lifting.  Span 4 will be lifted either late the week of March 7 or early the week of March 14.

February 2016

February 25, 2016

The stringers on Span 1 have been installed on all but one bay. That bay was left out to provide room for the crews to complete the backfill around Pier 2. The contractor will be removing the cofferdam from around Pier 2 beginning in March. Steel repairs on Span 2 should be completed the end of next week. Steel repairs on Span 3 will begin the week of February 29 and will continue for the next six to eight weeks. The Pier 3 footing has been poured and the contractor is working on framing the pier column. The temporary towers needed for the bridge lifting system will be reinstalled at Span 4 the week of February 29. The City now has a Facebook photo album devoted to the construction progress on the bridge.  https://www.facebook.com/pages/City-of-Bloomington-Minnesota/68661688425

February 19, 2016

Steel repairs on Span 2 will continue into the beginning of March.  The east abutment backwall construction is underway and should be completed the week of February 22. The temporary truss for lifting Span 1 is being removed.  It will be set aside temporarily and eventually installed at Span 4.  The temporary towers erected at Span 1 will be removed the week of February 22 and reinstalled at Span 4 the week of February 29.  Work continues at the Pier 3 footing.

February 16, 2016

The steel repairs on Span 1 are complete.   The contractor has poured the cap for Pier2.  The forms used to create the pier cap will be removed early the week of February 15.  The contractor will then lower Span 1 down on to the west abutment and Pier 2.  This is not as simple as it sounds.  Over time, various forces have pushed the bridge spans from their original location and they are no longer centered on the pier.  As part of the rehabilitation process, the spans will be put back in their original places.  This will involve adding a horizontal jack component, in addition to the vertical jacks that were used to lift the span.  The horizontal jacks will only be allowed to move a maximum of 1” increments to safely shift the bridge span back into position.  Once the truss has been moved to its final location it will be lowered back on to the pier and abutment.  When Span 1 is back on its foundations, the contractor will begin removing the dywidags rods that hold the bridge to the lifting truss.  The removal of the lifting truss for Span 1 will occur late in the week of February 15 and continue into the week of February 22.

Steel repairs on Span 2 will continue for several more weeks.  The contractor will be pouring the 16” piling at Pier 3 on Monday, February 15.  Once this is completed, the contractor will begin forming the Pier 3 footing and pour the concrete for the footing towards the end of the week.

February 5, 2016

The floor beams are going in on span 1.  The steel repairs on span 1 are on track to be completed the week of February 8.  Steel repairs on span 2 will continue for several more weeks.  The contractor is constructing the forms for the column on pier 2.  The forms are lined with pine boards in an effort to mimic the wood forms used in the original construction.  Span 3 has been lifted and demolition of pier 3 will begin the week of February 8.  Towards the end of the week the contractor will be pouring the 16” piling at pier 3.

January 2016

January 22, 2016

The contractor will be working on Saturday, January 23 to install channel bracing on Span 2 and has a noise variance to begin work at 7 am. Steel repairs continue on Spans 1 and 2. The work platform beneath Span 2 is partially installed and should be completed the week of January 25. Installation of the east abutment tiebacks also continues. The contractor will begin excavation at the cofferdam around pier 5 the week of January 25 and begin driving the 16” pile at this location.  The subcontractor who will be performing the heat straightening for the bent members on spans 1, 2 and 3 will begin late the week of January 25. The contractor is finishing the assembly for lifting Span 3. The lift is scheduled for the beginning of February.

January 15, 2016

Span 2 has been lifted which allows several new work tasks to begin. The contractor is winding down the demolition of pier 2. Once the demolition is complete, the contractor will begin forming for the concrete pier repair. Steel repairs will continue on Span 1 and will begin on Span 2. Installation of the work platform beneath span 2 will continue the week of January 18.  The east abutment tieback anchors have been redesigned and the work to install these will begin on January 18. The contractor is assembling the lifting system for Span 3. This work will include installing hanger beams and horizontal trusses. It is anticipated that the heat straightening for the bent members on spans 1, 2 and 3 will begin late the week of January 25.

January 8, 2016

Steel repairs continue on span 1 and will for a few more weeks. Steel repairs involve removing the existing rivets to release the rusted component identified during the inspection phase as needing repair. The conditions of the plate and bottom chord are verified against the inspection report. Since the inspection report didn’t involve removing the plates sometimes there is more rust than indicated in the report. The actual thickness of the steel is used and the loading calculations are rechecked using the actual value. The results are used to determine if the gusset plates, tee plates, angle irons etc. are replaced or reinstalled. At each joint, the contractor tents the area and removes the existing lead paint and rust. The tented area is heated and the components are repainted. If the connecting plate is being replaced, the existing plate is bolted to the replacement plate and the hole pattern is drilled using the existing plate as a template. Then joint is reassembled by installing the new plate using button head bolts that snap off when the appropriate tension is achieved.

The schedule for the week of January 11 may change given the expected cold snap. The current work plan includes lifting span 2 which will enable the contractor to demolish the deteriorated sections of pier 2. Once the demolition is complete, the contractor will begin forming for the concrete pier repair. The contractor will install a work platform beneath span 2 the week of January 11 as well.

December 2015

December 18, 2015

The first steel repairs will begin the week of December 21. Reconstruction of the west abutment back wall continues and is winding down. Work on installation of the horizontal truss for the shoring system located at span 2 continues, as does excavation within the cofferdam around pier 4. Work to begin reconstructing the east abutment back wall will begin in late December. Pile driving around pier 4 is tentatively scheduled to begin the week of December 28.

December 11, 2015

A milestone was achieved this week as span 1 is now hanging in the air from the shoring system. The contractor will be installing the work platform next week with the first steel repairs targeted for the week of December 21. Reconstruction of the west abutment back wall has begun and will continue the week of December 14.   

The horizontal truss for the shoring system located at span 2 will be installed next week. The contractor will also be installing and excavating the cofferdam around pier 4.

December 4, 2015

The contractor will begin installing piles around pier 3 of the bridge. Work on the shoring tower and horizontal truss for span 2 will occur the week of December 7, 2015.

The pull test for the south anchor on the west abutment did not provide the anticipated results. The results are being reviewed by the engineers for what the appropriate next steps are. Until this is complete, span 1 cannot be lifted and the demolition of the west abutment back wall cannot begin.

November 2015

November 25, 2015

The contractor will be winding down the construction of the coffer dam around pier 3 of the bridge. Once it is complete excavation within the coffer dam will begin. The lifting of span 1 is scheduled for the week of November 30. After it is lifted the contractor will install the work platform at span 1. This should be complete by mid-December.  Installation of the piles for the shoring foundation at span 4 will begin next week. 

The south anchor at the west abutment was successfully installed this past week. The pull test is scheduled for all the anchors the week of November 30. Once these tests are taken, the demolition of the west abutment back wall will begin.

November 20, 2015

The wind and rain slowed progress this past week. Shoring foundation piling for span 4 will conclude early next week. The contractor continues work installing the coffer dam around pier 3 of the bridge.  Work on beginning installation of the hanger beams and construction of the horizontal span 2 will occur prior to Thanksgiving. The lifting of span 1 is scheduled for the week of November 30.   

The pull test for the north anchor at the west abutment has passed. The south anchor at the west abutment ran into the H pile from the repair done to the abutment in the mid 1950s. The contractor jumped over to the east abutment to continue making progress. A third hole will be drilled for the south anchor at the west abutment to allow the tie back anchor to be installed past the H pile. Once this anchor is installed and tested reconstruction of the abutment back wall can begin. It is anticipated that this will begin early December.

November 13, 2015

Work on horizontal truss connecting the shoring towers at span 1 continues. The contractor will be installing lifting rods in preparation of lifting Span 1 which will either occur late the week of November 16 or early the following week. The actual lifting amount will only be between 6”-12”, only enough to allow access for Pier 2 to be reconstructed along with the bottom members of Span 1 to be removed, replaced or rehabilitated. 

Installation of the tieback anchors at the east abutment has begun and will extend into the week of November 16. The pull test for the north anchor at the west abutment is scheduled for November 13. This test will make sure that the anchor as installed has enough strength to prevent further movement of the west abutment. This abutment moved the first year after construction and experienced various repair projects throughout its life to try and counteract the movement. If these tests come back acceptable, the contractor will begin reconstruction of the west abutment backwall late next week.

The contractor continues work installing the coffer dam around pier 3 of the bridge. The shoring foundation pile around spans 3 and 4 will be placed the week of November 16.

November 6, 2015

The temporary access bridge is complete. The 16” pile installation under pier 2 is underway and will continue the week of November 9. Work on removal of span 4 decking was postponed and will occur next week. Drilling for the tie back anchors on the west abutment is complete. Insertion of the anchor and grout still needs to occur. Once this work is finished reconstruction of the abutment back wall will commence. This is likely to start late next week or early the following week. Work on the east abutment tie back anchors will begin sometime around Veteran’s Day. Erection of the horizontal truss connecting the shoring towers at span 1 has begun. Late in the week of November 9, the contractor will begin installing the coffer dam around pier 3 of the bridge.

October 2015

October 30, 2015

The contractor has decided to add one more temporary access span to reduce the size of the earthen approach on the east side of Long Meadow Lake. This is called the “jump” span and work on it is underway. This is the last temporary access span. Overall the temporary bridge construction went more smoothly than anticipated and it will be completed months ahead of schedule. 

Excavation within the cofferdam around pier 2 will continue next week. The rain this past week slowed down some of the cofferdam work. The contractor is building a template to ensure the angles of the driven pile will be correct and this has pushed the 16” pile installation under pier 2 until the week of November 2. The removal of the existing timber deck and stringers occurred this past week from span 5 instead of span 4. Work on removal of span 4 decking will occur next week. The subcontractor who is to install the tie back anchors on the west abutment was delayed on another project and is expected to be onsite the week of November 2 to begin work.

Erection of the shoring towers at span 1 has begun and will continue the next few weeks. The shoring foundation pile driving at span 3 will begin the week of November 2.

October 23, 2015

Work on temporary access spans 21 and 22 will occur the week of October 26. The contractor is considering adding one more temporary access span to reduce the size of the earthen approach on the east side of Long Meadow Lake. Excavation within the cofferdam around pier 2 will continue. Towards the end of the week the contractor will start installing the 16” pile to be placed under pier 2. The removal of the existing timber deck and stringer from span 4 is scheduled for the week of October 26. The second attempt at installing the tie back anchors on the west abutment will occur the week of October 26.

October 16, 2015

Work on temporary access spans 18, 19 and 20 will occur the week of October 19. Work installing the cofferdam around pier 2 continues. Once this is complete the excavation within the cofferdam will begin.

October 9, 2015

Work on temporary access spans 16 and 17 will occur the week of October 12. The tieback anchor casing on the west abutment encountered an issue which requires this casing to be remade prior to installation. Installation has tentatively been rescheduled for the week of October 26. The contractor will begin to construct the cofferdam around pier 2 the week of October 12. This cofferdam is a temporary enclosure that is built in a water body to allow the area inside the coffer dam to be pumped out and create a dry work environment for work activities. This is necessary for the foundation work that needs to occur on pier 2. Several more cofferdams will be built  with the project. The carrier beams will also begin to be installed across the shoring foundations in the area of span 1.

October 2, 2015

Work on temporary access spans 14 and 15 will occur the week of October 5.  The work on shoring foundation around Span 2 is winding down.  The tieback anchors will be installed on the east abutment.  Reconstruction of the west abutment backwall is scheduled to begin the week of October 5.  Bottom chord bracing on Span 3 will be placed on Monday, October 5 which will allow for the removal of the existing timber deck and stringers on Span 3 to begin.

The contractor has successfully drilled through the existing six foot wide west abutment pier 1 without hitting the existing H pile that was behind the abutment and installed with the 1957 repair of the abutment. This hole will be used to install the new tieback anchors to keep the abutment from moving further. The tieback anchors are currently scheduled to be installed the week of September 21.

The contractor is gaining speed on installing the temporary access spans and will be working on temporary access spans 5 and 6 the week of August 31. The contractor will be off loading concrete barrier that will be used as part of the heavy duty silt fence construction on the east side of the bridge. They will be temporarily storing this material on the Fish & Wildlife Service Archery Range. The delivery of the material is currently scheduled for September 1, and should only close the range for that day (weather dependent). 

Once access span 5 is complete, the contractor can begin removing the timber deck and stringers from existing span 1 of Old Cedar Avenue Bridge. This work is anticipated to begin in early September.

August 21, 2015

The contractor is finishing up temporary access span 3 and will begin temporary access span 4 the week of August 24. Crews expect to be far enough along with the temporary access spans by mid September that work can start on the historic bridge itself.

August 14, 2015

This past week the contractor excavated some of the contaminated soil at the existing piers.  Since the bridge was originally painted with lead paint, some of paint has flaked off and is found in the soil below.  As part of the rehabilitation project of the bridge, this contaminated soil is tested by environmental engineers who will make a recommendation on the proper disposal of the material.  Eventually new soil and riprap will be brought in to replace the contaminated material.

The contractor is finishing up temporary access span 2 and will begin temporary access span 3 the week of August 17.  Once the piles for the temporary access span are in, the contractor installs the stringers (longitudinal bridge girders for supporting part of the bridge deck between piers) between the piles which creates a place to install the timber decking which will be used as the work surface. 

US Fish & Wildlife Service has closed the parking lot adjacent to the Old Cedar Avenue Bridge project again.  This closure began on August 10 and will continue through October 16 to facilitate their trail construction.

August 7, 2015

The contractor will be finishing up temporary access span 1 installation and beginning the installation of temporary access span 2 the week of August 10.  This work involves driving 5 - 18” diameter pipe piles for each of the 22 temporary access spans.

July 31, 2015

Construction of the temporary access will continue the week of August 3.  Work activities include construction of the temporary abutment and beginning to place the first of 22 access spans.

July 24, 2015

The Century Link fiber has successfully been cut over and is now out of the way of the bridge construction.  The contractor will begin to install sheeting on Monday, July 27.  Later in the week, fill will be brought in to construct the temporary access ramp.

July 17, 2015

Century Link is prepping their fiber cable in anticipation of overnight cutovers scheduled for July 20 and 21.  The crews will work from 10 pm to 6 am.  There will be construction beacon lights and a generator necessary to complete the work.  Kraemer North America, the City’s contractor will begin work the week of July 27.

The fiber optic cable was placed in the conduit beneath Long Meadow Lake and the Minnesota River. Century Link will begin splicing the fiber.  This work is anticipated to be completed by July 24 so that Kraemer can move back into the site the week of July 27 and begin constructing the temporary bridge platform for the rehabilitation work.

June 26, 2015

Interduct cable was successfully placed beneath Long Meadow Lake.  Century Link crews will continue connecting the conduit to their cabinets and placing facilities within the duct.  Once this is complete, they will need to schedule time with each of their customers to perform the cut over from the old line to the new one.  This is anticipated to take approximately two weeks, but with the upcoming Fourth of July holiday it is unclear if that will help or hinder this cutover time.

US Fish & Wildlife Service also plans on starting some trail improvements west of Old Cedar Avenue in the next couple of weeks.

June 19, 2015

Last week we shared that the Century Link directional bore cable broke.  Instead of being 24 feet deep in a location where a rescue shaft could be dug as was shared at that time, Century Link speculates that the interduct snapped back like a rubber band and ended up 35 feet deep and beneath an oak tree.  A rescue shaft was no longer an option at that depth and location.  Century Link has acquired new interduct and will begin the drilling process again starting on Monday, June 22.

June 12, 2015

Century Link has made progress but it continues to be a struggle.  The interduct has been installed beneath Long Meadow Lake, but the pulling cable snapped approximately 100 feet from the tie in match point.  Century Link and their contractor will be bringing in an excavator to dig down 24 feet to the drilling head as part of the rescue shaft either June 16 or 17.  Given the close proximity between the rescue shaft and the connection point, the remainder of the interduct will be installed as an open trench.  An archeologist will be on site during the excavation of the undisturbed soil.

June 5, 2015

Century Link had a setback in their relocation of the Century Link fiber as one of the rods snapped on the back reaming operation. This means they had to remove all the rods from the hole and restart the drilling operation. Century Link will be working on this fiber relocation adjacent to the bridge for several more weeks.

May 2015

May 29, 2015

Century Link will continue to relocate their fiber optic lines that run parallel to the bridge in the way of the temporary bridge structure the week of June 1.

May 22, 2015

The week of May 25, Century Link will be relocating their fiber optic lines that run parallel to the bridge in the way of the temporary bridge structure.  The City contractor will be installing erosion control measures around the site and mobilizing the second crane into the site.

May 15, 2015

During the week of May 18, the contractor will continue to grade the staging area in advance of moving in the construction trailers and cranes.

May 8, 2015

Installation of fence around the staging area will begin on May 11.  Construction of a gravel trail that provides access to the Hogback Ridge Trail to the north of the staging area fence will also begin next week in order to maintain access to this Refuge trail.  Two other construction activities that are scheduled to occur are grubbing tree stumps and grading the staging area.

May 1, 2015

The contract books are still in process.  The contractor will begin mobilization as soon as they are approved which may be sometime during the week of May 4.

April 2015

April 24, 2015

The project was awarded at the City Council meeting held on April 20.  A preconstruction meeting was held on April 22.  Pending approval of the signed contract books, bonds and insurance the contractor anticipates mobilizing to the site to the week of May 4 and moving the crane in the week of May 11.

Staff continues to receive inquiries related to the US Fish & Wildlife Service (FWS) habitat restoration project in the vicinity of the Old Cedar Avenue Bridge and adjacent Bluff and Hogback Ridge Trails.  This FWS project is a separate and independent project from the bridge project.  Bridge construction has not begun yet.

April 16, 2015

The award of contract is on the agenda for the April 20, 2015 Council meeting.  Assuming the project is awarded, a preconstruction meeting is scheduled for April 22, 2015.

FAQs

Who presently owns the bridge?

The City of Bloomington is the current owner of the bridge. Ownership of the Old Cedar Avenue Bridge over Long Meadow Lake was transferred to the City of Bloomington by the State of Minnesota, along with the Old Cedar Avenue corridor, in 1981 shortly after the construction and opening of the TH 77 Bridge in 1980. The existing bridge is located in a narrow strip of public right-of-way, with the remaining area surrounded by federal property.

When was the bridge closed?

The existing bridge was constructed in 1920, after demolition of the 1890's wood structure. After independent bridge inspections in 1992 and 2002, the bridge was closed due to its poor structural condition to vehicular traffic in 1993, and to all traffic, including pedestrians, in 2002.

Would the bridge provide access to the Minnesota River Valley State Trail?

While the exact alignment of the Minnesota River Valley State Trial has not been set, it is presumed that it would be located adjacent to the Minnesota River and south of Long Meadow Lake. If this is the case, the Old Cedar Avenue Bridge over Long Meadow Lake would provide access across Long Meadow Lake to the Minnesota River Valley State Trail. The Old Cedar Avenue Bridge over Long Meadow Lake would be an important connection for birders, bicyclists, hikers, commuters, and others for access to the Minnesota River Valley.

The links below show trails in the vicinity of the Old Cedar Avenue Bridge over Long Meadow Lake, and the existing and proposed trails in the Bloomington area.

Since the bridge is deemed a regional asset by the City Council and Bloomington staff, should it be owned and maintained by a state or regional agency, and are there any other willing owners?

Over the past few years, numerous meetings have been held between the various local and regional agencies that have an interest in this project. Regional agencies include the United States Fish and Wildlife Service (USFWL), Hennepin County, Friends of the Minnesota Valley, the Lower Minnesota River Watershed District, Three Rivers Park District, the Minnesota Department of Natural Resources, and MnDOT. On several occasions, attempts were made to identify willing participants in future ownership and maintenance responsibilities. To date, all of the agencies have identified policy and funding challenges that make it difficult for them to participate in this project and none of the agencies have expressed interest in assuming ownership of the bridge. The most likely candidate has been the USFWL. Discussions are presently on hold pending future cost and environmental updates.

Is it possible to create a joint powers organization for maintenance responsibilities with other agencies?

Yes, it is legally feasible to develop a joint powers organization or a multi-agency agreement to share operations, maintenance, ownership and liability between agencies. The ownership and maintenance would need to be handled similarly to other regional trail assets. To date, there has been very little interest from regional agencies in such an agreement and none has been drafted for consideration.

Recently, others have indicated some willingness to explore limited participation in a joint powers organization. But no specific proposal has been forwarded.

Is the bridge a safety hazard?

City staff conducts annual inspections to monitor the structural condition of the bridge. The City has relied on the findings of an independent structural analysis by a qualified structural engineer in its decision to close the bridge. The City has also installed fencing, and has removed some of the bridge decking to deter trespassing on the closed public property.

The condition of the bridge is closely monitored. Currently, the bridge is not considered an undue safety hazard.

Do the National Environmental Policy Act requirements apply to the bridge project?

National Environmental Policy Act (NEPA) requirements apply to all projects that utilize Federal funds, involve Federal lands and/or require permits from Federal agencies. Since much of the trail is proposed to be built on property owned by the US Government and because its construction will most likely require permits from Federal agencies like the Corp of Engineers, the project will need to follow the environmental review outlined in NEPA.
