SR-710 North Study

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

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

No Build 

The No Build Alternative includes transportation improvement projects that are in the Southern California Association of Governments (SCAG) Regional Transportation Plan (RTP) programmed to be completed by year 2035. The No Build Alternative is required and serves as the baseline against which all other alternatives are compared. 

Transportation System Management/Transportation Demand Management

This alternative is designed to improve the efficiency of the existing transportation systems and reduce the demand in peak traffic periods within the Study area.  Strategies include traffic signal upgrades and synchronization, and local street and intersection improvements.

Bus Rapid Transit

Bus service on a Rapid line is designed for improving transit time for longer distance commuters with higher speed, high-frequency bus service, minimal stops, and potentially dedicated bus lanes.

Light Rail Transit

Rail service is proposed to directly serve communities from East Los Angeles to Pasadena. This alternative also includes bus feeder service variations to facilitate connectivity with adjacent communities.

Freeway Tunnel

The freeway tunnel alternative would extend State Route 710 as a high-speed, limited access roadway. All construction would be within existing right-of-way. Refinement options being considered for this alternative include: dual and single bore design, adding an Express Bus Service in the freeway tunnel, with and without tolls, and with and without trucks.

Next Steps:

  • Conduct environmental studies for each alternative
  • Continue public participation

Preliminary Study Schedule:

  • Circulate Draft Environmental document and conduct Public Hearing –

February 2015

  • Respond to Comments – 2015
  • Select Preferred Alternative – 2016
  • Final Environmental Document and Record of Decision – 2016

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