THE OTHER BRIDGE: Updated schedule for 1st Avenue South Bridge’s panel-replacement work

We checked in today with WSDOT on the status of the ongoing nighttime work to replace deck panels on the northbound 1st Avenue South Bridge. Here’s what spokesperson Tom Pearce tells us:

Our contractor has used five nights of full closures on the NB SR 99 Duwamish River Bridge. Per our agreement, the contractor is allowed to have nine more full closures. They are scheduling three more for Sept. 8-9-10.

During the next two weeks, the northbound bridge will reduce to one lane nightly Sundays through Thursdays, 10 p.m. to 5 a.m. No work on Friday or Saturday nights. These do not count against the nighttime full directional closures.

They have replaced six panels on the bridge; they still have eight to do.

As a reminder, if you have to cross the Duwamish late at night/early in the morning, the West Seattle low bridge is open to all 9 pm-5 am.

The northbound lanes on the 1st south bridge are not getting enough attention. There are still many sections that need to be replaced. At the rate the work has progressed, the contractor will need another two weeks to finish the work at least.
