Project Benefits

The five-legged intersection of the southbound ramp, Avila Beach Drive, and Shell Beach Road experiences significant congestion during peak hours, especially during weekend peak period. The general increase in traffic, coupled with the anticipated future traffic from planned projects in the area, is forecast to degrade this intersection to a Level Of Service 'F' by 2032. To reduce this congestion and maximize efficiency, the project will:

  • replace the stop-controls at the southbound ramp and Shell Beach Road intersection with a single-lane roundabout
  • install traffic calming features approaching the roundabout, including along the northbound off-ramp
  • provide a park-and-ride lot with bus stop

Estimated Construction Cost: $9 million to $13 million
