I-5 North Overview

View the project map
Caltrans is investing $1.3 billion to improve northern segments along the Golden State Freeway (I-5) between the Ventura Freeway (SR-134) and the Kern County line. Improvements listed below will enhance safety, improve traffic flow, reduce congestion, encourage ridesharing, decrease surface street traffic and improve air quality:

High-Occupancy Vehicle (HOV or carpool) Lanes – Carpool lanes for vehicles with two or more passengers
Direct HOV Connectors – Carpool lane connections so motorists can travel from one freeway directly to another without leaving the HOV lane
Interchange Improvements – On- and off-ramp improvements, bridge widening and bridge reconstruction
Truck Lane – New lane designated for truck traffic
Pavement Replacement – Extends the life of the road, lessens the need for maintenance and related costs as well as provides a smoother roadway surface
Grade Separation – Bridge crossing used to separate levels at which roads, railroads, or pedestrians use to cross one another
