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 interchange is expected to be complete and operational by December 2018.
