The Brief Caltrans' major repaving efforts resume along the 405 Freeway through the Sepulveda Pass starting tonight and extending continuously through Monday morning. Caltrans crews are resuming major repaving efforts along the 405 Freeway through the Sepulveda Pass. Along the southbound 405 Freeway, traffic will be squeezed down to just two open lanes between the southbound 405 connector to the 101 connector and the southbound 101 connector to the southbound 405. The northbound 101 connector to the southbound 405 will be fully closed, forcing drivers onto local detour routes, while the southbound 101 connector to the southbound 405 will be narrowed down to a single lane. These closures are part of Caltrans’ $143.7 million 405 Freeway Pavement Rehabilitation Project, designed to extend pavement life and improve safety between Van Nuys and Westwood.
