The California Department of Transportation (Caltrans) District 8 is performing ongoing pavement delineation work and installing conduit as part of the fiber optic communications project on State Route 71 (SR-71) through the fall of 2022. The fiber optic project involves installing Transportation Management System (TMS) field elements and a fiber optic communication system on SR-71.
Work will require alternating lane and on- and off-ramp closures of northbound (NB) and southbound (SB) State Route 71 (SR-71) between the Los Angeles / San Bernardino County line and State Route 91.
