MARIPOSA COUNTY – The California Department of Transportation (Caltrans) is conducting a pavement rehabilitation project on State Route 140 from the Mariposa/Merced County Line to approximately one mile east of Trower Road in Mariposa County.
To complete this project as expeditiously as possible, crews will work daytime and nighttime hours and employ one-way traffic control between 10 a.m. and 10 p.m. Monday through Friday until winter 2022.
Motorists should expect delays at times lasting ten minutes or longer and are advised to take alternate routes whenever possible.
Approximately 24 lanes miles of roadway will be ground then overlayed with rubberized hot mix asphalt (RHMA) to improve ride quality and prevent costly repairs in the future on a key route for residents, businesses, and visitors of Mariposa, surrounding communities, and Yosemite National Park.
The timing of the road work is due to industry-wide truck shortages, rising ambient temperatures for RHMA paving, and because this project and another are being supplied by the same plant.
The estimated $5.1 million project is being conducted by Cal Valley Construction of Fresno, CA.
This work is scheduled to continue as listed, but is subject to change due to traffic incidents, weather, availability of equipment, and/or materials and construction-related issues.
For the safety of workers and other motorists, please Be Work Zone Alert.
