We will replace the single-lane Pilchuck Creek Bridge in north Snohomish County on SR 9 and realign the road to improve sight distance.

Why is WSDOT replacing the Pilchuck Creek Bridge?
Of the 3,600 state-owned bridges in Washington, the Pilchuck Creek bridge is one of the oldest - built in 1916. At just 17 feet wide, the single-lane bridge is too narrow for modern safety and traffic standards. Yield signs on either end of the bridge let drivers take turns crossing it.

The SR 9 corridor in Snohomish County is the focus of major improvements. The corridor is the only alternative to I-5 and serves a number of rapidly growing communities.

The End Result
The new bridge will have two lanes (one in each direction) and shoulders, and it will improve safety and better meet the growing traffic demands of the area. We will realign the roadway to reduce the sharp curves and improve sight distance

Project Benefits
Safety: Replacing the single lane bridge with a wider, two-lane bridge that has shoulders will help improve safety and relieve congestion along the SR 9 corridor.

The roadway will be realigned to improve sight distance. Building the bridge on a new alignment will also allow us to keep the old bridge open during construction.

What is the project timeline?

  • The project was awarded to Granite Construction.
