WHAT HAVE BEEN ACCOMPLISHED:
JMEC has been prime design consultant for a pedestrian safety improvements & BPMP project, including repaving deck and applying slurry seal to the roadway at the intersection, replacing bridge barriers and approach railings for a bridge over Contra Costa County Flood Control District (CCCFD) Channel at Detroit Avenue. The project included widening the sidewalk on the bridge as much as practical and reduce the lane widths to a minimum of 11-ft in each traffic direction. This new sidewalk connects the existing sidewalk at north end and a new crosswalk at south end to create a continuous passage across the bridge. The Project Challenges and Solutions included materials testing as required to reconstruct as-built. Stage construction was used to allow through traffic during construction. The existing traffic signal was modified for the new crosswalk. The traffic striping along Detroit Avenue was re-stripped to accommodate lane shift due to the new bridge sidewalk
