The California Department of Transportation (Caltrans) proposes improving the crosswalk markings, delineation, and signs at each crosswalk location within four (4) different project limits. The work will occur in Merced County on State Route (SR) 152, from post mile 18.88 to 22.25; in San Joaquin County on SR-4, from post mile 15.80 to 15.87; in San Joaquin County on SR-12, from post mile 15.36 to 17.70; and in Stanislaus County on SR-108, from post mile 23.44 to 32.45. The scope of work will include selective grinding to remove the existing crosswalk markings and replacing them with ladder-type delineation. New warning signs will be installed for pedestrian crossings on new signposts. All work will occur in existing Caltrans Right of Way. The purpose of this project is to warn motorists of crossing pedestrians and vehicles stopped at these intersections. The project is needed to reduce the number and severity of traffic collisions near these intersections.
