The California Department of Transportation is set to begin a year-long project to upgrade its Transportation Management System, highlighting 46 different locations along Stanislaus County highways.

Work is scheduled to begin May 19 and expected to be completed in the spring of 2026. All told, between Stanislaus and San Joaquin counties, 49 different zones along seven different routes — highways 33, 99, 108, 120, 132, 219, and Interstate 5 — will be impacted at various times.

According to Caltrans, the upgrades will require daytime and nighttime work, depending on the location.

Daytime work will be performed Monday through Friday, from 7 a.m. to 5 p.m., and nighttime work will be performed Sunday through Friday from 7 p.m. until 6 a.m.

Upgrades include:

• Cameras for live traffic monitoring and incident reporting through Caltrans’ Transportation Management Center.

• Roadside Weather Information systems that collect and report local pavement and atmospheric data, which is used to alert the public to weather conditions, chain controls, and road closures.

• Changeable Message Signs that display traffic information, emergency alerts, and public service announcements.

• Vehicle Detection Systems that collect and analyze real-time traffic data to detect traffic incidents, traffic congestion, and control ramp metering. 

Locally, the intersection of Yosemite Boulevard (Highway 132) and Geer Road, and the area around the Enoch Christoffersen rest stop on northbound Highway 99 will be impacted. Additionally, the northbound Highway 99 onramp at Keyes Road, the Faith Home Road crossing of Highway 99, and the area south of Faith Home Road and northbound Highway 99 also are slated for upgrades.
