US 101 - SR 6 intersection improvements and drainage work

Project news

  • The roundabout project will be combined with drainage improvements in Raymond, along with paving and sidewalk work in South Bend.
  • Construction is scheduled for summer 2018.
  • Project was awarded to Rognlin's Inc. on April 12, 2018.

Why is WSDOT replacing the existing traffic signal with a roundabout?
The existing signal at the intersection of US 101 and State Route 6 is at the end of its useful life. Due to its age and corrosion from the salt air, the signal system needs frequent maintenance. Instead of replacing the signal, the Washington State Department of Transportation will build a roundabout that will keep traffic moving safely through the intersection and reduce long-term maintenance needs. 

In addition to intersection improvements, this project will also replace the failing drainage system with a new system between Heath and Duryea Streets, and add new sidewalks to the westside of US 101 in this same area. 

The End Result
Due to the it's age and the corrosion from the salt in the air, the current signal requires frequent maintenance, which takes extra time and money. Replacing the signal with a roundabout lowers the overall long-term operational and maintenance costs and improves the safety and traffic flow through the intersection.
