PA/ED stands for Project Approval and Environmental Document , which is a formal phase in the project development process used by transportation agencies like Caltrans and Metro. In this phase, agencies: Define the project scope and alternatives Conduct environmental studies (per CEQA and/or NEPA requirements) Engage the public and gather input Prepare and share environmental documents (like an Environmental Impact Report or EIR) Select a preferred alternative Obtain environmental clearance This phase concludes with the selection of a preferred alternative and environmental clearance—allowing the project to advance to final design and construction.

State Route 14 Safety and Access Study

Improving safety and reducing traffic congestion in North LA County

Project Type

Mixed-Mode

Current Phase

Planning

Metro, in partnership with Caltrans, is evaluating safety and mobility improvements along a 36-mile stretch of SR-14 between Newhall Avenue in Santa Clarita and Avenue P in Palmdale. This major corridor connects Los Angeles to the Antelope Valley and is critical for commuters and freight movement.

Early concepts under study include ramp improvements, new auxiliary lanes, and strategies to reduce congestion and improve access.

The project is currently in the environmental review phase, which involves technical studies and public input. Funding is provided in part by Measure M.
