Judd Creek Bridge is now OPEN! Two days early!


Judd Creek Bridge was built in 1951 to carry Vashon Highway SW traffic over the creek that leads to Quartermaster Harbor, just south of SW Quartermaster Drive. Growing traffic volumes and heavier vehicles have severely strained a portion of this 70-year-old bridge.

During the 21-day closure, contractor crews replaced:

  • deteriorating concrete that supported the bridge
  • worn-out bearings under the bridge
  • an expansion joint that allows the bridge to bend and flex with weather changes and heavy truck traffic.

Contractor crews secure the new beam into place.

Frequently asked questions

The north end of the bridge includes an expansion joint, a full-width concrete beam under the bridge, and four sets of bearings which allow the bridge to move with temperature changes.

King County inspectors routinely inspect all roadway bridges, including this one, per federal requirements. While the bridge on the whole is in very good condition, this north section of the bridge does require repair due to the deterioration of the concrete beam, bearings and expansion joint. The deterioration is partially due to the age of the bridge, combined with the growing traffic volumes and heavy truck traffic.
This bridge is located just west of Quartermaster Harbor on Vashon Island. Vashon Highway SW and SW Quartermaster Drive is the intersection to the north. Vashon Highway SW and SW 228th Street is the intersection to the south.

This section of Vashon Highway carries 4,800 (2-3% trucks) vehicles per day and connects Burton to the ferry terminal on the north end of the island. It also carries Metro Route 118 and several school buses. 
The estimated construction budget for this project is $200,000.
The project began on Monday, April 5, 2021 and was complete Monday, April 26, two days ahead of schedule.
