Mount Baker Highway Closure

Mount Baker Highway Closure

We’re just under a week away from a summer-long closure of State Route 542/Mount Baker Highway between Britton Road and Noon Road. Crews working for the Washington State Department of Transportation (WSDOT) will build a new bridge for the Squalicum Creek to Bellingham Bay Fish Passage Project. The contractor is set to close the highway on Monday, June 5, for up to 105 days. (The closure was previously scheduled to start May 30.)
 
What are the travel impacts?

Building the new bridge requires closing all lanes of SR 542/Mount Baker Highway between Britton Road (milepost 3.3) and Noon Road (milepost 3.5). Signed detour routes include:

  • Eastbound on SR 542 via north on Hannegan Road to East Smith Road to SR 542.
  • Westbound on SR 542 via East Smith Road, south on Hannegan Road, and back to SR 542/Sunset Drive.

To help deter travelers from bypassing the detour, there are additional closures at the following intersections: 

  • Kelly Road and Hannegan Road
  • Van Wyck Road and Hanegan Road
  • Van Wyck Road and Noon Road

Travelers will also see the speed limit reduced to 35 mph on Hannegan Road and a temporary traffic signal at the intersection of East Smith and Everson Goshen roads.
