About three miles of Northbound Interstate 5 will be closed to traffic south of Redding tonight, Caltrans says. The closure will detour drivers off I-5 at state route 273, and return to the interstate at South Bonneview Road. The closure will be in place from midnight tonight until five a.m. Wednesday.
Construction workers will be pouring concrete. The work is part of an effort to widen I-5 to six continuous lanes through Redding and Anderson. Southbound lanes will not be affected.
