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

Week of September 17 update

The second year of 66th Street (County Road 53) reconstruction is underway. Major work this year will occur between Humboldt and Portland avenues.

Below is what you can expect along 66th Street these next few weeks:

Road restoration work around I-35W interchange begins late next week

Crews will soon be wrapping up utility work between Humboldt and Emerson avenues. As a result, we will be doing several activities in this area near the I-35W interchange to restore the roadway.

We anticipate pouring curbs in the area on Friday, September 21, and Saturday, September 22. The following week, crews will be back in the area to pave. The area will remain open to local traffic, but please remember to allow extra time as crews will be on site and will need to move equipment through the area.

Reminder: 66th Street remains closed to through traffic

While crews are making progress and getting closer to starting road restoration around the I-35W interchange, the road remains an active construction zone. Work gets done quicker and we can maintain the temporary road better if we can keep traffic to a minimum. Rain and other weather challenges make it more challenging. Please use the area only if you live/work/are visiting the immediate area. Through traffic should continue to follow posted detours to Highway 62.  

Additional activities you should know about  

  • Utility replacement between Emerson Avenue and Lake Shore Drive
  • Concrete sidewalk installation between Lake Shore Drive and Nicollet Avenue
  • Pond construction at the southeast corner of 66th Street and Stevens Avenue  
  • Seeding between Pleasant and 5th avenues

Metro Transit bus stops under I-35W reopen mid-October

The eastbound and westbound bus stops on 66th Street under I-35W remain closed while major construction activities continue in the area (the bus stops on the I-35W ramps remain open). The bus stops are expected to reopen by mid-October; in the meantime, riders can still use the nearby bus stops at Humboldt Avenue or Lynwood Boulevard. 

Changing pedestrian detours in the area

Crews will continue pouring the concrete sidewalks between Lake Shore and Nicollet 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.

Metro Transit information

In order to maintain local service to residents during the 66th Street reconstruction, buses will be routed to local streets during major reconstruction (maps available for download below).

Metro Transit will have some bus stops temporarily closed during utility work and other activities as needed. The best way to stay updated on bus stop closures on your route is to visit Metro Transit's Rider Alerts website:www.metrotransit.org/rider-alerts.

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).
