Hiawatha-Lake intersection improvements

Highway 55 and County Road 3 in Minneapolis

Hennepin County and the City of Minneapolis are leading a partnership to make improvements to the intersection of Hiawatha Avenue (Highway 55) and Lake Street (County Road 3) in Minneapolis. In its current configuration the Hiawatha/Lake interchange area (Hi-Lake) is a difficult and uncomfortable place for people travelling regardless of mode of transportation.

Background: A partnership and collaboration with the community

In 2016, Hennepin County and the City of Minneapolis completed the phase 1 study in response to concerns about transportation issues at Hi-Lake. This technical study resulted in short-term and longer-term improvement options for all users.

In 2017, the partners engaged in phase 2. This phase included engaging with stakeholders and partnering agencies, as well as gathering community input through a public engagement process. This work led to a draft action plan that prioritized the improvements.

Short-term improvements: Work expected to begin in 2019

The city and county, with its partners at the Minnesota Department of Transportation and Metro Transit, have developed a plan to make short-term improvements to improve safety for all users while efforts are underway to make longer-term improvements. Both the city and the county will contribute to the estimated budgeted of $400,000 to modify the intersection in late 2019.

Hennepin County will lead construction efforts to make the short-term improvements. Current plans propose curb bump-outs and median refuge areas to shorten crossings, adding high visibility crosswalk markings and increasing walkway space.

Future improvements: Building a tight diamond intersection

Future improvements focus on a significant reconfiguration of the interchange to what is called a “tight diamond” design. The changes include simplifying movements for all users and improve traffic operations at Hi-Lake. This would include removing “free-right turn lanes” and realigning the connecting ramps to create more typical 90-degree type intersections.

 

The more extensive longer-term interchange reconfiguration is estimated to cost approximately $4 million. It will take time to plan and coordinate, as all partners who own or manage land or resources will have to collaborate. Funding and implementation year have yet to be identified.
