Caltrans and Metro are working together on the 710 North Study to evaluate mobility and find traffic congestion solutions between the western San Gabriel Valley and the east/northeast area of Los Angeles. The transportation network in this area was started more than half a century ago but was never completed.

Population growth will make traffic congestion worse and result in more traffic accidents, air pollution and related illnesses, and hurt the Southern California economy if nothing is done.

The Study is funded by Measure R, which was passed by two-thirds of Los Angeles County voters in 2008, mandating transportation upgrades throughout the County. The measure specifically allocates $750 million for the 710 North traffic congestion relief efforts.

What’s the status of the 710 North Study?

The release of the Draft environmental document is the next step in the process. Caltrans is the lead agency responsible for meeting CEQA and NEPA requirements and their environmental review process is still underway. As soon as the Draft environmental document is completed, we will post it online for public review.

Caltrans has extended the standard 45-day public review and comment period to 90-days, and will hold two public hearings. The public is encouraged to provide comments during this period, and will have several options to submit comments:

  • In person at the public hearings
  • By U.S. Mail
  • Online through the Caltrans public comment website

Study Timeline:

  • The Study’s Alternative Analysis was completed and the Alternative Analysis Report with five Alternatives was posted online on January 18, 2013.
  • The draft environmental document evaluating the five alternatives will be released in Feb 2015.
  • Public will have 90 days to review and provide fact-based comments
  • A preferred alternative will be identified in the final environmental document in 2016
