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).
