New carpool lane construction brings new slate of closures.

The California Department of Transportation (Caltrans) will close the following lanes, ramps and connectors of the I-5 and state route 14, as part of a new $161-million improvement project to construct High Occupancy Vehicle (HOV) or carpool lanes and a direct HOV lane connector at the I-5/SR-14 interchange.

In order to facilitate construction work as part of this improvement project, the entrance to the southbound I-5 carpool lane has been temporarily relocated south of SR-14 to just near the I-210 interchange.

This project involves the construction of an elevated two-lane direct HOV connector at the I-5 and State Route 14 interchange and construction of HOV lanes in both the north and south direction of I-5 at the Interchange.

A direct HOV connector will allow motorists a freeway-to-freeway transfer without exiting the carpool lane.

Preliminary work on this interchange improvement project began in July, 2008.
