66th Street (County Road 53) reconstruction

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.

Public involvement

Public meetings start in spring 2017

Hennepin County will be scheduling public meetings in spring 2017, before the first season of major street reconstruction begins. Sign up for project updates to receive advance notification by email or text about any scheduled public meetings.


Hennepin County will coordinate with local businesses to address access during major reconstruction. Project staff will begin reaching out to businesses in the project area in fall 2016 to collect contact information and learn about each business.

Previous events

The City of Richfield hosted an informational open house to provide a preview of project staging to the business community along the 66th Street corridor in January 2016. Below are handouts that were made available to attendees.

Closures and traffic access

Fall 2016

During preparation activities in fall 2016, some short-term lane closures and sidewalk closures will occur as needed. No full road closures will occur.

Travel during construction (starting in 2017)

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 lease 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).
