The Maricopa Association of Governments (MAG) launched the I-10 Deck Park Tunnel to I-10/I-17 Split Freeway Study to tackle persistent safety and congestion challenges on one of Arizona’s busiest corridors—serving over 300,000 vehicles daily. Public input highlighted safety as the top concern, so the study focused on reducing the corridor’s high crash rate—currently averaging five crashes per day.

Using a proactive, data-driven approach, the analysis quantified how design alternatives could reduce speed differentials, a key indicator of turbulent traffic flow strongly correlated to crashes. The recommended solutions target crash hot spots and mitigate vehicle conflicts through implementing braided ramps, ramp relocations and collector distributor roads. The team worked around several unique design constraints within the dense urban core. The proposed alternatives are projected to boost traffic throughput by 23% and cut average trip delays by 44%.
