Arizona Department of Transportation State Route 101 Loop (SR 101L), I-17 to Pima Road
The SR 101L project includes 14 bridge widenings, several thousands of feet of sound and retaining walls, and 14 miles of new general purpose lanes in both directions. The project utilized the design-build (D/B) method of delivery to help reduce the overall project timeline. The D/B method involves pairing civil engineering firms with construction contractors to create “design builders” who work synergistically from beginning to end. This method created more opportunities for innovation and reduced costs.
