US 101 - Matriotti Creek - Remove Fish Barrier


October 2017

  • US 101 near the Carlsborg Road and Hooker Road is temporarily reduced to one lane in each direction from milepost 260.6 to 261.2.
  • The speed limit will be temporarily reduced to 40 mph during the project.

Why is WSDOT replacing culverts under US 101 near Sequim?
The existing 5-foot diameter steel culvert that carries Matriotti Creek under US 101 is a barrier to fish passage.

Replacing the culvert with a much larger box culvert, measuring 10 feet high by 19 feet wide, will remove the existing barrier and open potential fish habitat.

Fish will be able to pass through this portion of the creek easier as the water will be slower and the structure will span a more natural creek environment.

What can drivers expect? 
The speed limit will be temporarily reduced to 40 mph.

Eastbound and westbound traffic will be reduced to one lane in each direction.

WSDOT will keep traffic moving by shifting traffic around the work zone. Drivers can expect two separate traffic shifts throughout project duration.  

The End Result
This new structure will open up approximately 5 miles of habitat.

In addition, the work will help preserve the integrity of the highway and reduce maintenance costs by reducing or eliminating the possibility of the blockages.
