Construction on State Route 94 + Millar Ranch Road

Construction has begun on the San Diego National Wildlife Refuge to construct approximately a 1-acre gravel-surfaced parking lot just east of the steel bridge and Sweetwater River, west of Millar Ranch Road, and south of State Route (SR) 94.


It is designed to accommodate approximately 43 vehicles, including five large-vehicle pull-through spaces and two Architectural Barriers Act (ABA)-compliant spaces. The new parking area will improve visitor access to the Sweetwater Interpretive Loop, which connects to the Sweetwater River Regional Trail, and supports the Refuge’s current and future interpretive, environmental education, and habitat restoration programs.

To ensure safe access from SR 94 into and out of the parking lot, several improvements will be implemented: 
  • a new westbound, left-turn lane from SR 94 onto Millar Ranch Road;
  • lengthening and improving the existing eastbound, deceleration right-turn lane from SR 94 onto Millar Ranch Road; and 
  • providing a new eastbound right-turn acceleration lane from Millar Ranch Road onto SR 94.

The refuge has been working with the Federal Highway Administration and the California Department of Transportation (Caltrans) to secure funding for this project through the Federal Lands Access Program (FLAP). The intent of FLAP is to improve transportation facilities that provide access to, are adjacent to, or are located within federal lands.
