Nicollet Avenue intersection closure continues through Tuesday, May 29

Crews are making progress constructing the new roundabout at the intersection of Nicollet Avenue (County Road 52) and 66th Street.

  • The new roundabout construction at the intersection of Nicollet Avenue (County Road 52) and 66th Street is nearing completion.
  • Paving of the concrete curb and roundabout pavement were completed last week. The concrete curb needs to continue to cure over the weekend before the roundabout can be opened traffic. We currently expect the roundabout to open by midafternoon on Tuesday, May 29, weather permitting.
  • The roundabout will open initially to a single lane of traffic as crews continue sidewalk work in the immediate area. You should anticipate congestion at the intersection and continue to use posted alternate routes when possible.

For the next several weeks, crews will be working on final sidewalk and driveway work, private utility adjustments and initial landscaping work in various areas. No full closures are expected, but you may see some lane closures or lane shifts.

Properties with temporary driveway access impacts for final driveway or sidewalk work will be notified in advance.

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).
