Caltrans District 8 has started work on a $122 million project on Interstate 15 near Hesperia this week to repave 59 miles of lanes and ramps. The project stretches from Oak Hills Road in Hesperia to Bear Valley Road in Victorville. Crews will be striping and placing K-rail along the highway today through Saturday on the Northbound lanes from 9 p.m. until 9 a.m. each day. Plan for delays, and take alternate routes if possible.
