I-605/I-60 Project

The Challenge

Interstate 605 (I-605, the San Gabriel River Freeway) and State Route 60 (SR-60, the Pomona Freeway) are essential components of the greater Southern California metropolitan area freeway network, with I-605 traveling north-south and SR-60 traveling east-west. The junction of these two freeways, at the borders of the City of Industry and the Avocado Heights unincorporated area, is one of the most important for freight movement between the Ports to the south and the Inland Empire to the east. Future growth in goods movement, as well as commuting populations, is expected to further impact an already overcrowded interchange system. For the benefit of residents, businesses, travelers, and truckers, it is important to support regional mobility by making improvements at the interchange and its approaches.

The Los Angeles County Metropolitan Transportation Authority (Metro) and the California Department of Transportation (Caltrans), in collaboration with the Gateway Cities Council of Governments (GCCOG) and the San Gabriel Valley Council of Governments (SGVCOG), are proposing to modify and improve the interchange.  On the I-605, improvements are proposed between Slauson Avenue and Interstate 10; on SR-60, improvements are proposed between Santa Anita Avenue and east of Turnbull Canyon Road. As part of the planning, Metro and its partners are committed to coordinating with other current and future area projects to minimize disruptions to local communities as much as possible.  They will also consider early action projects that can be implemented quickly and easily to ease congestion as soon as possible.

The Project is currently in the Project Approval & Environmental Document phase, which will study and evaluate environmental issues related to the proposed alternatives. [link to alternatives fact sheet]

The Project Area

The proposed project is located in the Los Angeles metropolitan area adjacent to the cities of Baldwin Park, El Monte, Industry, Pico Rivera, Santa Fe Springs, South El Monte, and Whittier, and the unincorporated areas of Avocado Heights, Hacienda Heights, Rose Hills, and West Whittier-Los Nietos.

Project studies are being funded through local Measure R funds.  Metro will also pursue additional federal, state, and other sources for future phases of the project.
