Widening and Realignment of 4 Miles of Roadway

The widening and realignment of Twin Peaks Road in the Town of Marana connects the growing communities of Continental Ranch and Dove Mountain in Arizona. The project consisted of the widening and realignment of four miles of rural two-lane Twin Peaks Road to a four-lane divided section.

Psomas provided preliminary design, Design Concept Report (DCR), and final design. The drainage element was extremely challenging due to the large number of crossings as well as the poorly defined wash boundaries and sedimentation issues. Acquisition of numerous parcels from private owners and state land was necessary in addition to extensive wildlife fencing and crossings.
