New roundabout to be built at Nisqually State Park

OLYMPIA – Construction is anticipated to begin on a new roundabout at the intersection of State Route 7 and Mashel Prairie Road near Nisqually State Park on April 7.

This work is being completed as part of the development of Nisqually State Park. Crews will construct a modern, one-lane roundabout with a raised center island. The existing intersection of SR 7 and Mashel Prairie Road is on a corner with limited visibility, so the new roundabout will make it safer for people visiting the state park, SR 7 motorists and local residents. 

The center island will include art contributed by the Nisqually Tribe, landscaping and a welcome sign for the new state park. Work is anticipated for completion by the end of July, weather permitting.

What to expect

The intersection will not close at any point during construction, but drivers should expect delays. Flaggers will be at the site to help direct traffic. 

All traffic will still be able to pass through the area during construction. This includes passenger vehicles, semitrucks and trucks pulling trailers. 

Nisqually State Park will also be closed for the duration of this work while development continues in the park. 

The Washington State Parks and Recreation Commission appreciates the patience of the community and visitors while construction is completed.
