During a routine inspection, our bridge operators discovered a hydraulic fluid leak on the Spokane St Swing Bridge (aka West Seattle Low-Level Bridge). To protect the safety of travelers and mitigate potentially costly cumulative damages, we will be conducting emergency repairs starting at 8 PM tonight, 6/20/18. The bridge will swing out of commission for a week or more and will be closed to vehicle traffic but open to marine vessels.
The leak is in one of the cylinder seals, shown above. To determine the extent of the damage, the bridge must be swung out in its open position and remain there during repairs.
What you can expect:
Our team is currently placing portable message signs on S Spokane St, east of E Marginal, facing WB traffic; the message to vehicle drivers:
“SPOKANE | BRIDGE | CLOSED
WEST OF | HARBOR | ISLAND”
Vehicle Detour Routes will begin at 8 PM and be clearly marked at the following locations:
- Chelan Ave SW
- 1st Ave S
- E Marginal
- Travel South on S Spokane St.
- North on E Marginal Wy S.
- East on S Horton St.
- South on 1st Ave.
- Take ramp to W. Seattle Bridge.
- Get off at SW Spokane Street exit.
- Turn right onto Chelan drive to the location.
- Travel West on SW Spokane St.
- Turn onto SW Avalon.
- Get back onto W. Seattle Bridge.
- Exit onto 1st Ave and travel back in reverse.
For tonight only, we’re providing van service for bike riders. Van service will stage at the approaches to and from Spokane St Bridge.
Our Bridges & Roadway Structures crews staff the City’s moving bridges 24/7. Director Paul Jackson said a leak gone unnoticed could cause increasing and eventually severe structural damage.
“Our bridge tenders don’t just sit in a tower—they inspect everything closely—over, and over again. I’m proud of them, though we all realize the repair work will cause significant traffic delays, we’re happy to have found the problem while it may still be small.” – Director Paul Jackson
It’s hoped the repair will be complete by the middle of next week, but that cannot be confirmed until the cylinder is opened and more thoroughly investigated for damage.
