West Cashmere Bridge Replacement (CRP 693)

West Cashmere Bridge Replacement (CRP 693)

CONSTRUCTION UPDATE

POSTED OCT. 9, 2020: The south truss of the bridge was removed earlier this week. The contractor will now demo the truss and remove it off site. The in-water work window has been extended through October. The contracter on Oct. 12 is expected to begin installing a cofferdam near the current bridge’s center pier. The cofferdam will create a dry working area where the new bridge’s center pier will be built. The center pier will be worked on over the winter. It will go in about 50 feet below the river and be about 10 feet in diameter.

The West Cashmere Bridge and Goodwin Road are closed. Goodwin Road is open to local traffic, which includes customers and vendors visiting the businesses on Goodwin Road.

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 will be built in approximately the same location as the existing bridge. The new bridge will 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 County coordinated with stakeholders to complete a planning-level study analyzing the access points into Cashmere, identifying their related freight routes and evaluating the old bridge to develop a scope of the type, size and location for its replacement.

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.
