Project Information
The City of Chico has obtained funding to replace the structurally deficient and functionally obsolete Guynn Avenue Bridge over Lindo Channel. The bridge is located between East Avenue and West Lindo Avenue, near the western edge of the City limits. The existing one-lane bridge provides a vital link between the Cussick Area Neighborhood and The Avenues, as it is one of only two vehicular crossings of Lindo Channel between Esplanade and Nord Avenue. The existing bridge is an 86-foot long, single-span, steel Warren pony truss bridge.
The bridge suffers from the following deficiencies:
- The bridge has significantly reduced load carrying capacity and can no longer bear the weight as originally intended.
- There is paint loss/cracking and rust on multiple steel members, including the main trusses of the bridge.
- The northwest wingwall has cracked and is beginning to fail.
- The bridge width does not meet current safety standards for cars and first responder vehicles.

To address these concerns, the City is planning to demolish and replace the existing structure. The new bridge will accommodate two 11-foot travel lanes, 5-foot shoulders, and a 6-foot sidewalk on the east side. The project improvements will extend approximately 200 feet north along Guynn Avenue and 100 feet both east and west along West Lindo Avenue. This single-span structure will be approximately 90 feet long. To facilitate construction, the bridge and a portion of Guynn Avenue, near the structure, will be temporarily closed to traffic. Traffic controls will be in place to guide vehicles, pedestrians, and biyclists during construction. The City will be working closely with the area residents to maintain access to their properties during construction.

The project is 100 percent federally funded through the Highway Bridge Program and Toll Credits. The federal funds are being administered through the Caltrans Local Assistance Program.

Studies
Environmental
An Initial Study for environmental review has been prepared for the project. Based upon the information within the Initial Study, the Public Works – Engineering Department is recommending that a Mitigated Negative Declaration be adopted for the project pursuant to the California Environmental Quality Act (CEQA). A Mitigated Negative Declaration is a determination that a project will not have a significant impact on the environment after the incorporation of specific mitigation measures. A 30-day public review period is being conducted on the Draft Initial Study / Proposed Mitigated Negative Declaration (IS/MND) commencing on Monday, March 17, 2025, and ending at 5:00 p.m. on Wednesday, April 16, 2025.
Comments relating to environmental concerns and the proposed Mitigated Negative Declaration must be filed in writing to the City of Chico Public Works - Engineering Department, P.O. Box 3420, Chico, CA 95927 or sent via email to tracy.bettencourt@chicoca.gov during the designated time period.
