I-10/SR 303L System Traffic Interchange (Phase I)

This five-level interchange connecting the I-10 Freeway and the SR 303L Freeway is a critical component of the 40-mile SR 303L, as it provides system continuity to I-17 to the north. The project constructed four flyover bridges and an embedded frontage road system, a unique design in Arizona that increased the overall footprint to yield the largest system traffic interchange in Arizona. Ultimately, as part of the five-level system traffic interchange, 14 bridges; including multi-span freeway ramps 75-feet above existing grade, were constructed.

The System TI generated over two million cubic yards of export which was used to provide two adjacent ADOT SR 303L corridor projects (concurrently under construction) with borrow material and other private development such as Dick’s Sporting Goods distribution warehouse.

A complex project in both size and scope, both ADOT and the design and construction team went above and beyond typical project management to truly partner with all stakeholders.
