27th Avenue Roadway Design

Hoskin Ryan re-designed the 27th Avenue roadway from Gary Way to Baseline Road. As part of the Silva Mountain Subdivision, complete re-design of the existing 27th Avenue roadway was required, including the design of a super elevated reverse curve, paving design, signing and striping re-design and storm drainage design.
In addition to the City of Phoenix, this re-design required coordination with the Maricopa County Department of Transportation, as portions of 27th Avenue were located within County Right-of-Way. Several private driveways were also affected by the re-design, requiring private property owner coordination. All topographic survey, boundary control and construction staking was also performed by Hoskin Ryan.
Project Requirements / Unique Characteristics:

  • Reverse/Super Elevated Curves
  • Multi-Jurisdictional Rights-of-Way
