SR 4 BYPASS TO BRING TRAFFIC
RELIEF, INCREASED MOBILITY
TO ANTIOCH, OAKLEY AND BRENTWOOD
Sacramento—California Department of Transportation (Caltrans) Director Will Kempton joined today with State Senator Tom Torlakson, officials from the State Route 4 Bypass Authority and other local representatives to break ground for the next phase of the SR4 Bypass.
Caltrans is overseeing the project and is a member of a state-local, public-private partnership to build the $103 million bypass, which is funded entirely through developer fees. The fees are collected on new development within the cities, as well as unincorporated areas, in eastern Contra Costa County. The State Route 4 Bypass Authority consists of Contra Costa County and the cities of Antioch, Oakley and Brentwood.
Segment 1 of the 12.4-mile bypass will provide six lanes of freeway between SR 4 and Laurel Avenue in Antioch, and four lanes of freeway between Laurel Avenue and Lone Tree Way. Segment 2 (already constructed) and Segment 3 will provide two lanes of expressway from Lone Tree Way south to Marsh Creek Road. The upgraded road will continue to Marsh Creek Road to reconnect to existing State Route 4.
“The project will help alleviate traffic congestion for motorists and increase mobility in the developing cities of Antioch, Oakley and Brentwood and provide smoother access to southeastern Antioch and western Brentwood,” said Kempton.
The project, which is scheduled for completion in the autumn of 2007, is expected to become the new SR4, subject to approval by the California Transportation Commission. It has been in planning for years. Work started formally in 1990 with formation of the State Route 4 Bypass Authority.
