Twenty to 30 minute traffic delays are expected in the southbound lanes of Interstate Five in Shasta County because of work that starts Monday, to make seismic safety improvements.
Cal Trans will begin preliminary work on the Sidehill and Dog Creek Seismic Retrofit project. It involves core drilling for design of a new structure.
The CHP will be conducting intermittent traffic breaks in all southbound lanes, from just south of O'Brien Road to within a mile of Turntable Bay Road.
This will occur between the hours of 6:00 a.m. to 10:00 a.m.
The traffic breaks are expected to last up to a half hour as a helicopter will be transporting equipment and materials and unloading them at the project site.
Caltrans crews will begin drilling operations and are expected to be finished by Thursday, July 31, 2014.
The Sidehill Viaduct was built in 1941, the Dog Creek Bridge was built in 1956 and both are in need of upgrades and repair.
