Project News

  • Travelers can expect one-way alternating traffic on the bridge from 8 p.m. Monday through Saturday to 11 a.m. each following day. Travelers crossing the bridge can expect 15-minute delays.
  • The speed limit is reduced to 35 mph. One sidewalk will remain open. There also are temporary commercial vehicle restrictions for oversize/overweight vehicles.
  • WSDOT encourages all users of the bridge to sign up for project updates. Get advance information about this project on the Kitsap and Mason County construction and travel updates web page.

Needs & Benefits

Steel truss bridges need to be regularly cleaned and painted to preserve their integrity and keep them in good working condition. The old paint is bubbled, corroded and peeling in places. Areas of rust are also visible. Once repainted, the bridge will be protected from weathering and deterioration, extending its useful lifespan. If the bridge was not repainted, the steel would eventually deteriorate from rust.

How will the work be done? 

WSDOT will work to keep people moving and minimize delays whenever possible. The bridge will be reduced to one-way alternating traffic at times during nighttime and early morning hours. One sidewalk will remain open. Crews have established a temporary sidewalk across SR 305 near the bridge on Bainbridge Island. 

Due to the bridge’s size, work will be performed in sections. 

  • Install a containment system to help protect the environment.
  • Construct a platform within the containment system to provide a work area for crews.
  • Sandblast away the paint until crews reach bare metal.
  • Apply new primer and paint.
  • Remove the work platform and containment system.


  • Work began summer 2019.
  • Crews returned March 2020 
  • Project is expected to be early fall 2020.
