The Arizona Department of Transportation, in cooperation with the town of Florence and Maricopa Association of Governments (MAG), will begin a project to reconstruct the intersection of State Route 287 and SR 79B with dual roundabouts. 

Key elements of the project include:

  • Constructing a multiple-lane roundabout at SR 287/SR 79B
  • Constructing a single-lane roundabout at SR 79B/Florence Heights Drive
  • Realigning the west end of Florence Heights Drive
  • Reconstructing local streets and driveways within the project limits
  • Constructing new sidewalks and multi-use pathways to improve accessibility 
  • Installing new curb and gutter and stormwater systems including retention basins within the project limits 
  • Replacing and improving roadway lighting
  • Adding aesthetics include decomposed granite, decorative median paving and town entry monument

Work is beginning December 2023, with the majority of the work completed by Summer 2024.
