Past Projects » Jalama Road Bridge Replacement

Construction of the Jalama Road Bridge Replacement has been completed months ahead of schedule. The contract for the bridge replacement was awarded to Souza Construction by the Board of Supervisors on March 24, 2015 and work began on April 16, 2015. The contract allowed 240 working days to complete the work which was accomplished in only 190 working days.


After initially falling behind schedule, the contractor worked tirelessly to finish the project before the onset of highly advertised El Nino storms.


The bridge now meets current safety standards and includes two 12’ travel lanes and 5’ shoulders. The project cost $4.2 million with 88.53 percent of the money coming from the Federal Highway Bridge Program. The 11.47 percent matching funds were provided by state and local sources.


Design and construction oversight for the bridge was performed by a team of County staff and consultants.


The Public Works Department would like to thank local residents, cyclists, pedestrians and the traveling public for their patience and cooperation during this much needed bridge replacement.


Update 12/30/2015

Jalama Road is currently open and the traffic signal is off but still in place as well as the signs for lane closures as needed. We are currently finishing the fences, bike rail, concrete surfaces (grinding), and staining barrier.

Update 12/08/2015

Stage 2 of the bridge deck was complete on November 30, 2015 and the road was paved December 1, 2015 ahead of schedule! All work is now scheduled to be complete by December 31, 2015 weather permitting.

Update 11/13/2015

Active construction continues on Stage 2 of the bridge deck; it is scheduled to be complete November 16.  The Stage 2 bridge work including barrier rails and a concrete closure pour between Stage 1 and Stage 2 is scheduled to be complete by November 30, weather permitting.


The bridge on Jalama Road at milepost 8.8 did not meet current design standards. The Federal Highway Bridge Program and State Proposition 1B Seismic Program supplied a grant to replace the bridge, with local match funding provided by Measure A.

 

The new bridge is a 160 foot single span structure consisting of 6 precast-prestressed concrete spliced bulb tee girders with a reinforced concrete deck and barrier rails founded upon 4 cast-in-drilled hole concrete piles at each end.

 

The new bridge is being built in 2 Stages due to the high cost of realigning the roadway and the infeasibility of a temporary bridge for traffic to bypass the work site.  A temporary signal system is in place to control one lane traffic through the work site.

 

Stage 1 of this bridge is scheduled to be complete (the Eastbound lane of the new bridge) by October 2015. Environmental Permits restrict some portions of the work during the rainy season, from December 1, 2015 to May 1, 2016.  The contractor is currently working hard to condense the remaining operations in order to finish work over the creek by December 1 and open the new bridge to the public ahead of schedule.
