SR 120 - James E. Roberts Memorial Bridge Project
DESCRIPTIONThe James E. Roberts Memorial Bridge was built in 1970 and is on State Route 120 in Tuolumne County. It spans Don Pedro Reservoir and is a popular route for the 4 million visitors who annually enter Yosemite National Park, where iconic Half Dome rises 4,800 feet above the Yosemite Valley floor. The project will provide a new bridge deck and railimgs, strengthen the existing girders, improve the bridge's seismic strength and reduce the need for frequent repairs.
- Eliminate inconsistent roadway surface conditions;
- Provide a modern and safe bridge for vehicles and bicycles;
- Put an end to frequent minor deck repair projects;
- Stop exposing maintenance personnel to safety risks;
- Extend service life of the bridge an additional 40 years.
Yosemite National Park plays a critical role in the economy of Tuolumne County, as it is the northwest gateway into the expansive national park. The purpose of this project is to extend the service life of the bridge; enhance safety; increase capacity and improve traffic operations; and provide a transportation facility consistent with local, regional and statewide plans, and Caltrans’ standards.
The total construction cost is estimated at $20.8 million and it is programmed in the State Highway Operation and Protection Program.
The State Route 120/James E. Roberts Memorial Bridge project in Tuolumne County got under way in early July 2016. Workers will replace the bridge deck and retrofit the structure to provide an additional 40 years of service.
One way-traffic control is in effect and will be throughout the $20.8 million project, which is scheduled to finish in November 2017. A portable signal is being used to manage traffic on the bridge and motorists are scheduled to wait no longer than 10 minutes.
The project will provide a new bridge deck and railings, strengthen existing girders, improve the bridge's seismic strength, and reduce the need for frequent minor repairs.
This work is subject to change due to traffic incidents, weather, availability of equipment and/or materials and construction related issues.
