Find out about TriLink – a potential new transportation link between Brentwood and Tracy

Residents of Contra Costa, San Joaquin, and Alameda County are invited to attend a series of three Open Houses to learn about a potential new transportation link between Brentwood and Tracy.

Twelve local communities, including Antioch, together with environmental and business advocates, are collaborating to explore the feasibility of creating a high quality transportation facility that would connect State Route 4 near Brentwood to the Interstate 580/205 corridor near Tracy.

Known as TriLink or State Route 239, this facility could potentially improve access for those who live and work in the region, and support inter-regional goods movement operations that create jobs locally.

First identified in 1959, SR-239 is a legislatively approved, but unconstructed route in the California state highway system. SR-239 is a potential multimodal link between SR-4 near Brentwood and I-205 west of Tracy in San Joaquin County. The route has not been adopted by the California Transportation Commission (CTC); however, Contra Costa County was awarded $14 million for initial study and planning under SAFETEA-LU in 2005. Administration of the study, now called TriLink, was transferred to the Contra Costa Transportation Authority (CCTA) in January 2012.

Learn about how TriLink could affect the region and what route options are under consideration. Come to any of the following open house meetings:
