Construction is expected to begin June 27 on State Highway 21 northwest of Stanley. In the coming weeks, crews will replace an old culvert at Elk Creek (milepost 123.06) with a new bridge.

“The current culvert was placed in 1966 and has exceeded its life expectancy,” ITD Designer Andrew Young said. “The new structure will be both wider and longer and will serve motorists for decades to come.”

The new bridge also aims to improve fish habitat in the area.

“When we build the new structure, we will be providing a better natural channel that will be more favorable to fish,” stated Young. “We will also have temporary fish passage in place during construction.”

While construction is underway, traffic will be reduced to a single lane. Temporary traffic signals will be in place to direct motorists through the work zone. Drivers should anticipate delays up to 15 minutes when traveling through the area.

Braun Jensen is the primary contractor on this project that is expected to be complete this fall.
