Caltrans says delays of 20 to 30 minutes are anticipated from south of O'Brien Road to south of Turntable Bay Road between 6 and 10 a.m. from July 21 to July 31.
The California Department of Transportation, Caltrans District 2, is scheduled to begin preliminary work Monday, July 21, on the Sidehill and Dog Creek Seismic Retrofit project. Preliminary work will consist of core drilling for design of a new structure on Interstate 5, according to a press release.
The California Highway Patrol will be conducting intermittent traffic breaks in all southbound lanes, 0.2 miles south of O’Brien Road to 0.4 miles south of Turntable Bay Road, between 6 and 10 a.m., according to Caltrans. The traffic breaks are expected to last between 20 and 30 minutes.
Caltrans says a helicopter will be transporting equipment and materials and unloading them at the project site. Caltrans crews are expected to begin drilling operations with an anticipated completion date of July 31.
The project is designed to address the seismic safety of the Sidehill Viaduct, built in 1941, and the Dog Creek Bridge, built in 1956. Both are in need of upgrades and repair, according to Caltrans.
The traveling public is reminded that, by law, you are required to move over if safe or slow down when you see Caltrans vehicles flashing warning lights along the side of the highways.
