East Bush Lake Road/I-494 Interchange - West Bound Ramp

What is the scope of the project?

The East Bush Lake Road (CSAH 28) at I-494 interchange has been without a westbound on-ramp since its construction in 1960. Since that time, development and redevelopment has occurred in the Normandale Lake area with the emergence of a number of high-rise office towers, hotels, four- and five-story office buildings, townhomes and high-rise condominiums to the north and south of I-494. A westbound ramp will relieve traffic problems in the area and assist in more efficient operation of the already congested interchange at TH 100/I-494.

This map shows the roadway, bridge and signal modifications necessary to add a westbound on-ramp to the existing infrastructure.

How is the project funded?

The City of Bloomington has applied for and received funding from: Minnesota’s Transportation Economic Development Program granting $8 million; another $7.3 million grant from the Federal government's Congestion Mitigation/Air Quality program, and Hennepin County, which will provide an additional $8.5 million. This total of $23.8 million from the project partners fully funds the project. 

What is the project's schedule?

The beginning of the operation of the interchange is targeted for 2018.

Next week the contractor will be driving piles for a retaining wall and will begin to tie steel rebar into the correct shape for a future concrete pour.

January 19, 2018

January 12, 2018

The contractor returned to the site earlier this week and left again due to the cold weather.  They intend to return on Wednesday, January 17, weather permitting.   They will be working on installing retaining wall piling and forming and pouring various concrete structures on the south side and in the median of I-494. 

December 2017

December 21, 2017

With the cold weather forecast for the week of December 25, the contractor does not plan on working that week.  Pile driving will resume on January 2, 2018, weather dependent. 

December 15, 2017

Pile driving continues both on the south side and in the median of I-494.  The contractor will be forming and pouring the concrete for the retaining wall footing as well.

December 8, 2017

The contractor will be excavating the existing pond on the south side of the interstate. They continue to install forms and rebar for the south abutment. The contractor is also moving equipment into the median of I-494 in preparation for installing pile for the center bridge pier, which will begin the week of December 11.

December 1, 2017

The contractor will be working on constructing the south abutment footing the week of December 4. Work will also begin on an adjacent retaining wall. The contractor continues to push a 48” pipe under I-494. Once the pipe is installed, the contractor will begin digging to expand the existing water treatment pond.

Pond excavation and relocation of the surcharge dirt pile will occur the week of November 13. Pile installation for the south abutment will begin as well.

November 3, 2017

Miscellaneous electrical work will occur the week of November 6, moving electrical poles in the work zone. Dewatering of the pond will begin towards the end of the week. This will allow pond excavation and south abutment pile installation during the week of November 13.

The traffic switch to allow the median I-494 pier construction timing continues to be adversely affected by the weather and end of the construction season scheduling. The contractor is still attempting to have this occur yet this fall, however the work may end up moving to the spring of 2018.

October 2017

October 27, 2017

The contractor will continue excavating and hauling materials for the south abutment and the adjacent retaining walls the week of October 30. A traffic switch to allow the median I-494 pier construction is tentatively scheduled for the night of October 31, weather dependent. Once this traffic switch occurs the contractor will begin driving sheeting and excavating for the median pier footing.

October 20, 2017

The westbound I-494 north (outside) shoulder will be closed starting October 23. The contractor will be clearing and grubbing trees and brush in the project area, including a section of American Blvd where the anti-icing building will be constructed. Once this is complete, the contractor will begin grading and hauling material for preloading the south abutment. This is necessary due to some compressive soils in the area.

October 13, 2017

The schedule has been updated slightly and advanced notice signing for upcoming construction will be placed the week of October 16. Mobilization of equipment along with clearing and grubbing is scheduled for the week of October 23, with work in the median of I-494 to begin the week of October 30. This will require lane shifts on I-494.
