The James E. Roberts Memorial Bridge, which serves as the northwest gateway to Yosemite National Park along Highway 120, will get a series of repairs after the Fourth of July, Caltrans said.
“The bridge is critical to Tuolume County, and to the park,” Caltrans spokesman Rick Estrada said.
Caltrans hopes to improve traffic conditions and minimize the need for repairs in the future.
The project will begin Wednesday and will continue until November 2017. Workers will lay down a new deck and railings, as well as strengthen existing girders to improve the bridge’s seismic strength.
Never miss a local story.
The bridge will use one-way traffic control during repairs, with automatic signals allowing drivers across the bridge one lane at a time. Caltrans does not expect anyone to wait longer than 10 minutes to cross the bridge.
Starting in October, workers will close the bridge Sunday through Thursday nights from 5 p.m. to 7 a.m., when they will replace the old deck. The deck is expected to be repaired by February of next year.
The bridge will be closed completely for a week after the deck is finished for joint seal repairs.
La Grange, Bonds Flat and Jacksonville Roads are available for detours around the bridge. Other detours are noted online.
