Guynn Bridge Replacement Project

The Guynn Bridge Replacement Project, identified by solicitation number BUT-59478-R2, involves the demolition and replacement of a structurally deficient single-lane bridge over the Lindo Channel in the City of Chico, Butte County, California. The project scope includes the construction of a new 90-foot precast prestressed concrete box beam single-span bridge featuring two 11-foot travel lanes, five-foot shoulders, and a six-foot sidewalk on the east side. Technical requirements include the installation of concrete abutments on deep foundations and the application of approximately 80 cubic yards of rock slope protection as scour countermeasures. The project is subject to several regulatory approvals and environmental mandates, including a Streambed Alteration Agreement from the California Department of Fish and Wildlife and approval from the Central Valley Regional Water Quality Control Board. Under the California Environmental Quality Act, the project was determined to have no significant environmental impact, provided that specific mitigation measures and monitoring plans are followed. Necessary site preparations include the removal of riparian trees and vegetation, such as elderberry shrubs, to facilitate construction. The project is located at latitude 39.74359 and longitude -121.87591.
