Clough Creek Bridge #909B Load Upgrade Project

The project was completed in August 2023.

Clough Creek Bridge

The short-span bridge over Clough Creek on 415th Way SE is old and had a 22-ton load weight limit. The load limit restriction was removed upon completion of this project.

Status update

August 21, 2023

Crews successfully completed the Clough Creek bridge load upgrade project on August 18. 
These upgrades make so heavy trucks weighing over 22 tons are able to use the bridge for years to come.

Overview

Clough Creek Bridge is a 16-foot-long span located on 415th Way SE at SE 141st Street south of North Bend, WA.

More than 1,300 vehicles use the 73-year-old bridge every day. The support girders under the old bridge deck were old and could no longer bear the weight of commercial trucks. This project removed the deteriorating concrete beams and replaced them with new prefabricated concrete girders. These upgrades restored the bridge to its original strength and makes it possible for trucks heavier than 22 tons to use the bridge.

Frequently asked questions

The entire bridge will be closed to all traffic, including all emergency response vehicles. This means all emergency responders must use the detour to drive around. We will continue to keep emergency responders (fire, police, sheriff) notified of our construction schedule so they can plan ahead.
We will update this website with more information leading up to the start of construction. In the meantime, please contact Broch Bender (Bbender@kingcounty.gov) with any questions or concerns.
The bridge is too narrow to open a lane of traffic and maintain enough room for construction equipment and crews to do the work.
Clough Creek Bridge is 16-feet long and 24-feet wide.
More than 1,300 vehicles use the bridge every day.
