TheBristol Street Widening Project is the first project in Southern California to achieve Greenroads Bronze Certification for its commitment to sustainable transportation construction and traffic solutions.

Bristol Street Phase 2 is a major north-south corridor traffic improvement project that carries more than 42,000 vehicles each day and runs through the heart of Santa Ana. The project was substantially complete in November.

The new 2,600 foot-long bioswale runs between the north and south lanes. The unusually flat area created a challenging condition for managing surface runoff.

The Bristol Street project implements traditional sustainable transportation features including:

  • bicycle lanes, bus turnouts and sidewalks
  • the use of old car tires and recycled asphalt for paving
  • the identification of local suppliers reduced the carbon impact and boosted the local economy
  • LED lighting 
  • cleaning surface runoff with a beautifully constructed half mile long, 15-foot-wide bioswale
