Project overview
This project upgraded and replaced key elements of the SR 104 Hood Canal Bridge. The project bolstered the system that guide the two halves of the bridge together and keep them connected.
What to expect
This project is complete.

The SR 104 Hood Canal Bridge is truly unique. Massive hydraulic systems lift, retract and extend the driving surface of the bridge. The movement creates an opening large enough for marine traffic.
A key element of this bridge helps keep both halves of the bridge together. The area, called a center lock, is similar to a door’s deadbolt. During this project, crews bolstered the center lock to better withstand tremendous forces, especially during powerful winter storms and fast-moving tides.
Crews have also made permanent repairs to another system. Twin metallic objects shaped like pyramids on one half of the bridge help guide the bridge into dual receivers located on the second half of the bridge. Workers temporarily removed both systems - called pyramids - and a large metal plate that secures the pyramids in place. Crews then reinstalled the metal plate and the pyramids using industrial-sized bolts.
The repairs will extend the ability for the bridge to open for marine traffic and close the draw span for all travelers crossing the SR 104 Hood Canal Bridge. With no convenient alternate routes between Kitsap and Jefferson, repairing the bridge preserves an important lifeline for residents and businesses.
