February 22 - The Repair of the West Seattle Bridge

Abstract

More than 2 years ago, the West Seattle Bridge was closed to traffic over serious and potentially catastrophic safety concerns. In January 2022 a project began to complete repair and re-strengthening of the bridge so it could be re-opened it to the public. This presentation will focus on that unique, fast-paced project and the many challenges along the way to accomplish this major goal for the City of Seattle.

Presenter: Tim Barry, RS&H
