FOR MOKELUMNE RIVER BRIDGE REPAIRS EASTBOUND & WESTBOUND STATE ROUTE 12 BETWEEN SR-160 AND INTERSTATE 5
Stockton – The California Department of Transportation (Caltrans) is planning a series of highway closures of eastbound and westbound State Route 12 (SR-12) between SR-160 and Interstate 5 (I-5) for repair work on the Mokelumne River Bridge located at the San Joaquin/ Sacramento County line.
Caltrans will perform one-way traffic control at the SR-12/Mokelumne River Bridge beginning Sunday, March 29 through Friday, April 3, 2020, from 9:00 p.m. until 5:00 a.m. These closures are required to prepare for the bridge work during the upcoming 55-hour closures. Boat traffic will not be impacted by these closures.
Caltrans will then perform a 55-hour full closure of SR-12 beginning on Friday, April 24 at 10:00 p.m. until 5:00 a.m. on Monday, April 27, 2020. Work scheduled during this closure includes removal of the bridge “end jacks,” which secure the movable bridge back into alignment with the roadway after having opened for boat traffic.
Three additional 55-hour full closures are also required through the month of May 2020 (dates yet to be finalized) to replace the “end jacks” and to remove and replace the center main bearing, which allows the movable bridge to swivel open for boat traffic and return back into alignment with the highway for motorist travel.
** No lane closures are scheduled during the Memorial Day weekend of May 22-25, 2020. **
