During the inspection one side of the bridge will be closed while traffic flows on the other side with one way traffic control assistance. March 20 and 21 Northbound CA-160 will be closed.

Antioch Bridge Lane Closures (Mar. 2015)

Caltrans is reminding motorists that one-way traffic controls will be in effect on the Highway 160 Antioch Bridge as crews perform routine inspections of the span this week and next week. Crews will alternate lane closures in both northbound and southbound directions, with flaggers and a pilot car helping direct traffic. The work is slated from 9 a.m. to 2 p.m. on four consecutive weekdays – Monday through Thursday of this week and March 16 to 19 next week. This will allow one traffic lane on the bridge to remain open during the inspections. Motorists should expect delays and allow for extra travel time. Work is dependent on the weather. Vessels will pass normally beneath the bridge on the San Joaquin River.

Planned Closure of Elmira Lane to Begin January 27 (2014)

As part of the Buskirk Avenue Widening Phase 2 Improvement Project in Pleasant Hill, California, Elmira Lane will be closed to public traffic for three months starting on Monday January 27, 2014. 
This road closure duration may change depending on weather, field conditions and work conflicts. Buskirk Avenue traffic will be routed through single lane of two-way traffic through the newly constructed Buskirk Avenue (old S-curve) around the perimeter of the shopping center. One new traffic signal will be operational at Buskirk Avenue/Clarie Drive and two stop intersections will complete the detour along Buskirk Avenue; one at the south shopping center entrance and a second at Hookston Avenue (both of these are currently in place). Detour signs will be in place to route traffic around the Elmira Lane road closure.
The City of Pleasant Hill’s project contractor, Ghilotti Bros., Inc. is switching traffic to move on to the next stage of work. The next stage will involve all project improvements along the east side of Buskirk Avenue and Elmira Lane, including Clarie Drive.  For more project information, please see visit the City’s Buskirk Avenue web page at or contact the City’s Construction Manager, Jeff Ocampo at (925) 671-5208 or by email at
