Project Overview

Part of planning for future growth of the 303 Freeway roadway project included a plan to construct interim improvements to the Cactus, Waddell and Bell crossroads. These improvements would minimize disruptions to traffic, retail, commercial, and residential developments adjacent to State Route 303.

The expected challenges on this project were right-of-way acquisition and relocation of irrigation facilities. To tackle potential right-of-way issues, the team developed a phasing plan to work around areas where right-of-way was not yet acquired, maintaining the project’s completion date. The team addressed the irrigation coordination by creating an action plan and coordinating closely with the Maricopa Water District (MWD). The use of BIM helped identify a clash of an irrigation line over the top of a box culvert, which would have been exposed and ended up in a sidewalk. The team worked with MWD and their designers to design the irrigation line to be placed under the box culvert.

The majority of the work on the project was performed by Sundt crews, which gave the team additional control over the challenging schedule. The project required:

  • 41,000 square yards of Portland cement concrete paving
  • 210,000 cubic yards of roadway excavation
  • 26,000 tons of asphalt paving
  • 8,000 linear feet of storm drain and irrigation pipe
  • 54,000 tons of aggregate base course
