Document Description
The project is located in northern Los Angeles County, and extends from Interstate 5 (I-5) on the west to State 14 (SR-14) on the east. SR-138 Northwest Corridor Improvement project proposes to improve the highway as a freeway, expressway with access control and/or traffic system/multi-modal facility. Four alternatives are identified for the project corridor. Alternative 1 is an expressway facility throughout the entire corridor. Alternative 2 is a freeway/expressway facility throughout the entire corridor. Alternative 3 is a traffic system/multi-modal facility throughout the entire corridor. Alternative 4 is the No-Build Alternative. These alternatives may be refined, combined with various different alternatives, or be removed from further consideration, as more analysis is conducted on the project alternatives.
