SDOT announced today that it’s set the date for a surface-traffic closure starting October 7th and lasting “approximately one week” to reinstall the cylinder removed last January. From the announcement:
… The next step in the maintenance process is to reinstall the turn cylinder that was removed from the low bridge’s east pier housing last winter for refurbishment. When the east pier’s cylinder was removed last December, preparations to overhaul all four of the bridge’s hydraulic turning cylinders were actually already underway as part of our comprehensive repair and maintenance effort. When the unexpected damage to the cylinder occurred, the planning work we had already completed enabled us to quickly jump into developing a response plan and likely allowed us to complete repairs sooner than if we had been starting from scratch.
The turn cylinder overhaul work will replace or repair these parts so that they can continue to function as originally designed, and can be readily replaced if needed, as part of our ongoing preventative maintenance work on this bridge.
From Saturday, October 7 through Saturday, October 14, 2023, crews will reinstall the repaired turn cylinder inside the east pier housing that was removed in early 2023. The remaining three turn cylinders will also be rehabilitated in the future. This operation will require us to close the low bridge for people driving, biking, and walking for approximately one week. Our work will be vital to keep the bridge reliably in operation for today and the future.
The announcement also says that free Transit GO credits will be provided so you can take a daily bus or Water Taxi round trip at no charge. (Metro had previously announced that the Water Taxi will be out of service October 14-15 for winter preparation, so we’re checking to see if the low-bridge closure is expected to end by October 14, or whether some overlap is possible.)
