The Interstate 605 (I-605, the San Gabriel River Freeway) corridor is located at the center of Southern California’s freeway network and is one of the busiest and most congested transportation arterials in Los Angeles County, specifically between Interstate 105 (I-105) and Interstate 10 (I-10). Continued growth in the region’s population and employment, as well as substantial projected growth in goods movement, are expected to add further pressure to the existing traffic capacity and operations within this corridor. In order to ease congestion and support future growth, additional capacity along with operational and safety improvements are needed for the benefit of the residents, businesses, travelers, and interstate commerce.
The Los Angeles County Metropolitan Transportation Authority (Metro) and the California Department of Transportation (Caltrans) District 7, in collaboration with the Gateway Cities Council of Governments (GCCOG) and the San Gabriel Valley Council of Governments (SGVCOG), are proposing improvements along I-605 between I-105 and I-10 as part of the I-605 Corridor Improvement project (project). In addition to improving I-605 within the corridor, the proposed project includes improvements along State Route 60 (SR-60) from west of Peck Rd to east of Turnbull Canyon Rd and along Interstate 5 (I-5) from Florence Av to the Rio Hondo Channel. The cities adjacent to the project limits include: Baldwin Park, El Monte, South El Monte, City of Industry, Whittier, Pico Rivera, Santa Fe Springs, Downey, Norwalk and unincorporated parts of Los Angeles County.
Improvements will revitalize the heart of Southern California’s freeway network, allowing people and goods to move freely, which will stimulate and support a robust economy capable of growing with the region and demands of the future.
The project goals are to:
- Ease congestion and add freeway capacity where needed.
- Improve freeway operations, mobility, and travel times.
- Enhance regional connectivity and freeway interchange efficiency.
- Improve safety.
Project studies are being funded through local Measure R funds, the 2008 local sales tax. Metro will pursue additional Federal, State, and other sources for future phases of the project, including construction.
