We are building a new overcrossing from Bickford Avenue to westbound US 2 in Snohomish to reduce the risk of serious collisions. We are also replacing five failing drainage culverts located beneath both eastbound and westbound US 2 between the Ebey Slough Bridge and Bickford Avenue near Snohomish.

Why is WSDOT improving the US 2/Bickford Ave. intersection and replacing culverts beneath the highway?

The US 2/Bickford Avenue intersection was the site of more than 2 dozen collisions between 2006 and September 2013. More than 20 involved drivers turning left from Bickford Avenue onto US 2. The new overpass will help reduce the risk of serious collisions at the intersection by taking traffic over US 2 rather than across US 2.

The culverts beneath US 2 that carry water runoff from the roadway and surrounding areas are deteriorating. The corrugated metal pipes are corroded, allowing water to seep in under the roadway and causing the material beneath the highway and median to settle. WSDOT repairs and maintains the culverts, but they have reached their maximum lifespan and need to be replaced to preserve the roadway.

We replaced the culverts with new pipes made of thick, heavy, rubberized plastic. To accomplish this, crews opened up the roadway, removed the old culverts and installed new pipe. This required closing one direction of US 2 on six separate weekends in the summer of 2012. We alternated directions each weekend and closed the roadway from Friday night through Monday morning. Detours were in place during the closures.

The End Result
The new overpass at Bickford Avenue will help reduce the risk of collisions by allowing drivers to safely cross and merge onto westbound US 2. The new culverts will provide proper drainage for water runoff and prevent further damage to the roadway.

Project Benefits

New Bickford overpass:

  • The new bridge and ramp will reduce congestion by eliminating the current intersection.
  • The overpass will reduce the number of collisions because drivers will cross over US 2 instead of crossing through traffic.
  • New and upgraded lighting will increase visibility for drivers.

New culverts:

  • Replacing the culverts will prevent settlement underneath the highway.
  • New culverts will provide proper drainage for roadway water runoff.
  • The new culverts will reduce annual maintenance costs.
