66th Street reconstruction

County Road 53 in Richfield 

The county, in coordination with the City of Richfield, will be building a county road designed to be safer, more livable and welcoming to all uses, while balancing potential impacts to residents and businesses along the corridor.

The project extends from Xerxes Avenue on the west end to 16th Avenue South on the east end.

Progress updates

Late October to early November update

Season wrap up work continues for the next several weeks

Crews will be working hard during the next few weeks to finish the final construction activities for this year along the 66th Street corridor, including:

  • Concrete sidewalk installation on the south side of 66th Street between Humboldt Avenue and Lake Shore Drive 
  • Retaining wall construction between I-35W and Lyndale Avenue
  • Permanent signal installation at I-35W and Lake Shore Drive
  • Temporary asphalt sidewalk and driveway installation on the north side of 66th Street

With fewer major activities, we anticipate sending fewer updates about the project in the coming weeks. We encourage you to check www.hennepin.us/66street for updates, and you can contact the project at 612-444-3186 or 66street@hennepin.us with any questions.

Detour remains for through traffic

Even though construction is nearing completion for the year, we would like to remind you that the corridor remains closed to through traffic for the short term as crews continue to work in the area. The most efficient route for all through traffic is the marked detour using Xerxes Avenue (County Road 31), Highway 62 and Cedar Avenue (Highway 77).

For local traffic, please anticipate lane shifts on 66th Street as side street paving, driveway and sidewalk work remains ongoing in the area. 

Additional activities you should know

Metro Transit bus stops

The eastbound and westbound bus stops on 66th Street under I-35W will reopen next week after sidewalk installation is complete. Until then, riders can still use the nearby bus stops at Humboldt Avenue or Lynwood Boulevard. 

Metro Transit bus shelters

During the next few weeks, crews will be installing bus shelters at Lyndale and Nicollet avenues and near I-35W. 

Changing pedestrian detours in the area

Crews will continue pouring the concrete sidewalks between Humboldt and Emerson avenues.

Be aware the pedestrian detour route will change at times during this phase of work. Pay attention and follow the signed route at all times, or call 612-444-3186 if you have questions or need help navigating around the area. 

Detours, closures and traffic access

Closure for through traffic

66th Street (County Road 53) is closed to through traffic between Cedar Avenue (Highway 77) and Xerxes Avenue South (County Road 31). The purpose of this closure is to allow crews to reconstruct the roadway and complete utility improvements along the corridor as part of 66th Street reconstruction project.

There will be local access to all residences and businesses.

Local traffic access

Getting to local businesses and residences

The project team will be working to maintain access for residents and businesses as much as possible during construction, and will provide signed detours for any closures that are needed. In general, the following is expected:

  • At least one pedestrian access route will be maintained at all times.
  • One lane in each direction will be provided for vehicle traffic during the majority of the work (please note this may be a gravel surface).

During major reconstruction activities, please allow some extra time to reach business destinations.

Environmental coordination

Hennepin County has been working in close coordination with the Environmental Protection Agency (EPA), Minnesota Pollution Control Agency (MCPA) and the Minnesota Department of Health (MDH) regarding the vapor intrusion site at 66th Street/Vincent Avenue South.

Environmental assessment

As part of the preparation to begin construction on this project, the count prepared an environmental assessment. Because the file size is large, the related document has been broken down into multiple files.

The county hosted an environmental assessment open house on February 18, 2016 at the Richfield Community Center. Comments were also accepted by email or US mail to the project engineer.

In May 2016, the Federal Highway Administration published its Finding of No Significant Impact (FONSI) (PDF).
