N. Pima Rd. & E. Stagecoach Pass

Scottsdale, AZ


As part of our on-call contract with the City of Scottsdale, MTJ Roundabout Engineering was tasked with development of a concept roundabout design at this high-speed rural intersection. The concept design is in support of feasibility determination and programming purposes.


The resulting concept horizontal geometric design was predicated on application of traffic/highway engineering and modern roundabout design principles and criteria working together to optimize safety for this high-speed rural application.

Key Project Outcomes:

  • Address driver expectancy for high speed context
  • Minimize adverse impacts
  • Accommodate large trucks/freight
  • Transit and school buses


  • 135′ single-lane design
  • Provisions for residential access near intersection
  • ROW constraints
  • Minimized adverse impacts
  • Large trucks/freight accommodations
  • Addressed driver expectancy for high-speed context
