Project will Repair and Replace Deteriorating Pavement
July 6, 2023 - STOCKTON – The California Department of Transportation (Caltrans) is preparing to begin a maintenance project that will improve the roadway surface of State Route 140 (SR-140) between East Whitlock Road and the Yosemite National Park entrance in Mariposa County.
Work will include the repair of failed roadway surface locations using hot-mix asphalt, along with the installation of concrete barriers and transitions, guardrails, signage, and new electrical systems. Overnight, alternating lane closures on eastbound and westbound SR-140, will be required for the safety of motorists, roadway workers and equipment.
Beginning Monday, July 17, 2023, crews will work night shifts, for approximately 180 working days - Sundays through Thursdays - with completion expected in April 2024. Overhead and roadside message signs will be placed on SR-140 to alert motorists of scheduled highway lane closures. Detour signs will also be posted on surface streets.
This $25 million project was awarded to Teichert Construction (Fresno, CA), who will perform the work required.
This project will benefit residents and tourists traveling to and from the town of Mariposa to Yosemite National Park, as well as motorists and commercial vehicles traveling throughout Mariposa County and beyond.
By improving the roadway surface, this project will also improve mobility and greatly reduce current and future maintenance repair costs for this highly traveled corridor.
Caltrans will provide continuous updates on scheduled lane and ramp closures, and any other lane closure details in future traffic advisories and social media posts.
