About the Project

Caltrans is constructing an HOV lane in each direction on I-5 between the Hollywood Freeway (SR-170) and SR-118, a distance of 6.8 miles (3.4 miles in each direction). The project is also widening four undercrossings, replacing sections of pavement, and building a direct HOV connector at the I-5/SR-170 interchange. A direct HOV connector allows for freeway-to-freeway transfers without exiting the carpool lane.

This project will alleviate congestion, encourage carpooling, improve air quality, and provide a smoother ride for motorists. The work is part of Caltrans’ effort to provide motorists with a seamless carpool lane network in California.

Work began in August 2010 and is on track for completion in late 2013. Caltrans thanks motorists for their patience and understanding during construction.
