The two movable work platforms attached to the West Seattle Bridge could be brought down before Christmas. That’s part of today’s weekly SDOT update on ongoing bridge-related work. Lowering the platforms back down onto a barge will mark the end of what SDOT refers to as “Phase 1 Stabilization” – primarily involving carbon-fiber wrapping and strengthening with steel cables (“post-tensioning”). Contractor Kraemer North America is also wrapping up work on replacing the damaged bearings at Pier 18 (in this case, “pier” refers to a bridge support). The stabilization work had to be done first regardless of whether a repair or replace pathway was pursued; next comes repair design and contractor selection.
On the low bridge, installment of the new enforcement cameras is complete; SDOT tells us, “We are planning on testing the new system through December, and expect to begin issuing notices for unauthorized bridge usage in early 2021.”
