Caltrans has scheduled five overnight closures of Willow Road and U.S. 101, as part of the Willow Road/U.S. 101 Interchange project. The closures will allow crews to install 135-foot concrete girders for the new overpass. During the following closures, affected lanes of Willow Road will be closed 11 p.m. to 6 a.m. All closures are dependent on the weather. Rainy weather may cause work to be rescheduled. Changeable message signs along the freeway and adjacent routes will keep motorists apprised of the status of the closures.
