The environmental impact report for California’s Northwest 138 Corridor Improvement Project has been completed. The report was produced jointly by the 2451 California Department of Transportation and the 3227 Los Angeles County Metropolitan Transportation Authority. When the project is complete it will boost safety and cut congestion on SR-138 between the I-5 and SR-14 in the north of Los Angeles County. The area suffers heavily from traffic jams and delays are common for road users. The studies into the options available showed that the best alternative was for the expressway/limited access conventional highway. However the sections of SR-138 that will not be incorporated into the route improvements will now become local access roads.

The plan calls for a six-lane divided Freeway and Expressway running between the I-5 interchange to Gorman Post Road and from Gorman Post Road to 300th Street West. The plan also includes four-lane divided Expressway and Limited Access Conventional Highway from 300th Street West to 240th Street West and from 240th Street West to SR-14. However financing for the work has yet to be established.
