Shasta County, California Bridges: Cypress Avenue Bridge across the Sacramento River

April 2015 (40.5721 Degrees, -122.3732 Degrees) Cypress Avenue Bridge
We continued downstream along the Sacramento River to the Cypress Avenue Bridge. It's a five span haunched girder bridge on pier walls built in 2011 (that replaced an older bridge). A placard on the west (far) abutment shows the City of Redding is the owner, T Y Lin was the designer, Parsons Brinkerhoff (PB) was the project manager, and Kiewit was the contractor. The project cost $72 million but there were 40 claims from Kiewit including an $18 million claim due to problems driving the temporary steel casings for the large diameter shafts that support the bridge. PB was in charge of resolving the claims.

The aesthetic features include haunched girders and oversize pier walls supporting decorative pylons above the deck. The bridge has attracted many homeless people who live in a tent city under the easternmost approach span (on the near bank in the photo).
