Press Release: County Awards $19.3 million Contract to build new Cashmere Bridge

Letter to Local River Rafting and Kayaking Companies (March 4, 2020)

 

Project Description

The West Cashmere Bridge is a 91-year-old, fracture-critical bridge, both functionally obsolete and structurally deficient, with a sufficiency rating of 25.18. It is currently posted for both weight and height restrictions. The new structure is proposed to be constructed in approximately the same location as the existing bridge. The proposed bridge is estimated to be 44 feet wide and 1,000 feet long. In February 2020, a $19.3 million contract was awarded to SB Structures of Seattle for the construction of the new West Cashmere Bridge.

In 2012, through these fracture-critical inspections, it was estimated that within 10 years there would be a substantial decrease in the bridge’s load-carrying capacity – due to the progressive deterioration of the structural elements – unless major rehabilitation of the bridge’s structural components are performed.

The Chelan-Douglas Transportation Council has considered the West Cashmere Bridge Replacement Project to be of regional significance and is one of the top three priority projects within Chelan and Douglas counties.
