BUTTE & GLENN COUNTIES, CA (MPG) - Caltrans will fully close the Butte City Bridge on State Route 162 (SR-162) overnights from Thursday, March 13 through Wednesday, March 19 to allow crews to install joint assemblies across the new bridge deck. The closures will take place nightly from 9 p.m. to 5 a.m., during which time no traffic will be permitted on the bridge.

A detour will be in place directing motorists to use State Route 45 (SR-45) to Ord Ferry Road to 7 Mile Lane, which leads to Road Z and back to SR-162. Drivers should be aware that the detour includes single-lane, signal-controlled traffic on the Ord Ferry Road Bridge across Little Chico Creek, with a speed limit of 15 mph. Oversized vehicles must comply with an 18-foot width restriction on Ord Ferry Road between SR-45 and 7 Mile Lane.

The bridge closure is part of a $114 million replacement project that began in 2022 and is expected to be completed in 2026. The project aims to improve safety and extend the lifespan of the bridge while enhancing roadway conditions along the corridor. In addition to replacing the aging structure, the project includes upgrades to drainage systems, improved signage and striping, and accessibility enhancements to meet Americans with Disabilities Act (ADA) standards. Caltrans advises motorists to plan ahead, allow for extra travel time and follow posted detour signs.

Caltrans District 3 is responsible for maintaining and operating 4,385 lane miles in 11 Sacramento Valley and Northern Sierra counties. Caltrans reminds motorists to “Be Work Zone Alert” and slow in construction zones for the safety of travelers and crews performing these improvements.

The department will issue updates on X @CaltransDist3 and on Facebook at CaltransDistrict3.
