State Route 71 - Caltrans Freeway Projects
State Route 71 Pavement Delineation and Fiber Optic Installation Projects
(Caltrans District 8)
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.
Work will take place at various times during the daytime and evening hours and is expected to be completed in the fall of 2022.

State Route 71 Freeway Conversion Project
(Caltrans District 7)
In spring 2021, Caltrans District 7 began a project along SR-71 to increase freeway capacity and relieve existing traffic congestion. The project will widen SR-71 between Interstate 10 and the Los Angeles/San Bernardino County line to convert the existing 4-lane expressway to a full 8-lane standard freeway and provide carpool lanes on SR-71 between Interstate 10 and State Route 91. The work will involve adding one mixed-flow lane and one High Occupancy Vehicle (HOV) lane in each direction and replacing two existing bridge structures over railroads and an existing pedestrian overcrossing as well as constructing retaining walls and sound walls.
