Metro Report Concludes 710 Freeway Tunnel Is the Best Option

May 13, 2017 – On Wednesday, the Los Angeles Metropolitan Transportation Authority (Metro) Ad-Hoc Congestion, Highway and Roads Committee will discuss an informational report and status update regarding the 710 freeway.  The State Route 710 (SR 710) North Project environmental report concludes that “…the technical studies completed over the past few years clearly capture the mobility benefits included in the Single Bore Freeway Tunnel (SBFT), with tolls and truck restrictions…"

“The latest report validates the Coalition’s long-standing position that the tunnel is the best solution for completing the 710 freeway,” said Ron Miller, Executive Secretary of the LA/OC Building and Construction Trades Council.  “The issue of the 6.2-mile gap between the 10 and the 210 freeways dates back to 1959. It is time to stop studying and start building a tunnel that completes the freeway and improves traffic for the region as a whole,” added Miller.  

Metro and Caltrans have made significant strides toward completion of the 710 freeway.  In 2011, Metro, in partnership with Caltrans, initiated the environmental review process and related preparation of the SR 710 North environmental document.  In 2012, LA Metro released a list of five alternatives to be studied as part of the SR710 North Project Draft Environmental Impact Report (DEIR.)  A freeway tunnel was among the proposals.  More than 300 informational and community-related meetings have been held to inform the public about the project and related environmental process.  Over 1300 support letters were submitted for the tunnel.   

“We’re talking about a severe environmental injustice here,” said Alhambra Mayor Dave Mejia. “The San Gabriel Valley has suffered for too long.  Let’s stop debating and start building.”


The 710 Coalition formed in 1982 continues to support the tunnel as the best alternative for completing the freeway.  A freeway tunnel will reduce congestion and air pollution in local neighborhoods, provide a missing link to the gap in a regional freeway system, reduce emissions and decrease cut-through traffic in surrounding communities.  The tunnel reduces emissions and local street vehicle miles traveled: by 9% in Pasadena, by 12% in South Pasadena, by 7% in San Gabriel and by 14% in Alhambra. The member cities include Alhambra, Monterey Park, Rosemead, San Gabriel, and San Marino.  For a complete list of supporters and more information about the 710 Coalition, please visit us at our website: To read the Metro overview of the 710 North Study, click here.   To review the Metro Fact vs. Fiction document, click here
