Carmel Country Rd. & Carmel Mountain Rd.

San Diego, CA

OVERVIEW

MTJ Roundabout Engineering was retained to evaluate the feasibility of a roundabout at this commercial, highly constrained intersection.

SUMMARY

Alternative concepts addressed these key issues:

  • Minimize/avoid undesirable ROW impacts to surrounding properties
  • Ensure compatibility with existing and/or proposed roadway cross sections, to include ped and bike design features – cycle track and on-street bike facilities
  • Accommodate necessary design vehicles:

 

    • Large trucks/freight
    • Transit and school buses
    • Emergency response/fire trucks

Three alternatives were developed to evaluate optimal size/shape and fit with acceptable impacts.

The resulting compact style design allows the central island to retain landscape features that will promote visual conspicuity for this application.

HIGHLIGHTS

  • Minimized undesirable ROW impacts to surrounding properties
  • Compatible with existing roadway cross sections, including cycle track
  • Accommodated large trucks, transit/school buses, emergency response vehicles
  • Non-circular compact style roundabout
