Cost-benefit Analysis will Inform City’s Decision to Repair or Replace the West Seattle High-Rise Bridge

Now we must decide whether the repair or a replacement option is the best path to restoring travel across the Duwamish.

Just last week, the TAP released an official statement sharing that the information they have reviewed indicates repairs appear feasible and recommend we continue to explore the repair option fully, along with various replacement options.

This statement is in agreement with our bridge engineers’ and our bridge consultant WSP’s current analysis, and it marks the end of review about whether repair is possible. Now the critical question is whether repair of the High-Rise Bridge is advisable, relative to other replacement options available.

We are currently undergoing a cost-benefit analysis to better understand and assess the full range of repair or replace concepts.
