With the SR-710 North Study underway, we’re closer than ever to shaping the future of transportation and mobility in your community. After years of gridlock and discussion, two-thirds of Los Angeles County voters approved the passage of Measure R in 2008. As a result, Metro is in a position to address traffic relief and make transportation upgrades throughout Los Angeles County. For decades, the road and highway system that has served as the heart of our County’s transportation lifeline has seen significant impacts stemming from growth and congestion. The San Gabriel Valley, with over 20% of the county's population, is no exception.

At their June 2010 meeting, Metro in coordination with the California Department of Transportation (Caltrans), adopted motions to move forward with the environmental review phase and broaden the search for multi-modal solutions for the State Route 710 (SR-710) study area. You, the community, participated in a series of meetings held in March and April 2011, during scoping, the first step in the project’s environmental review.

What’s next for the SR-710?

The SR-710 North Study team will be working with stakeholders in person and online as the environmental review process unfolds. This process involves an education and public involvement program to seek both regional and community-based solutions that are suggested by you, your friends, family, neighbors, and everyone else in your community. A range of ideas could be considered – from maintaining the status quo to considering new infrastructure, to multi-modal approaches. We encourage you to regularly visit this website and our social media channels, which will evolve to offer more information on how you can make your voice heard. Help us spread the word!

The study team completed the Alternative Analysis phase of the study and posted the Alternatives Analysis Report online on January 18 2013. 

The five alternatives that performed best against the screening criteria and that will be studied in depth in the Draft Environmental Impact Report/ Environmental Impact Statement (Draft EIR/EIS) are:  

  • No-Build
  • Transportation System Management/Transportation Demand Management (county-wide strategies to improve and enhance traffic operations)
  • Bus Rapid Transit (provides fast and frequent service between East Los Angeles and Pasadena)
  • Light Rail Transit (provides aerial and tunnel rail service between East Los Angeles and Pasadena, with connection to Metro Gold line)
  • Freeway Tunnel (connects the north and south termini of the existing SR 710)

Next Steps:

  • Refine build alternatives to improve performance and avoid/minimize potential impacts
  • Conduct environmental studies, preliminary engineering and technical analyses for each alternative
  • Continue public participation

Preliminary Study Schedule:

  • Conduct geotechnical investigations within the study area by Spring 2013 involving soil/rock borings, groundwater level measurement, and vibration testing
  • Circulate Draft Environmental document and conduct Public Hearing by Spring  2014
  • Final, Environmental Document and secure Record of Decision by Spring 2015

There are no SR-710 meetings scheduled at this time. Please check back frequently for more information.
