The state of Arizona has received two federal grants for Corridors of the Future-related construction projects.

The first is $1.2 million to widen I-10 in Maricopa County, between Sarival Avenue and Loop 101.

The second is $1.8 million to construct a new bridge across the Colorado River, to provide an alternative to the Hoover Dam crossing. The current route, on US 93, has sections with sharp turns, narrow roads, poor sight distance and low speed limits. In addition, federal travel restrictions put in place after 9-11further slow traffic on US 93 near Hoover Dam.

US 93 connects I-40 to I-15 (a Corridor of the Future) in Las Vegas, saving truckers headed north a half-hour over an alternate route along US 95 (the only other route involves a 250-mile detour into Barstow, CA and back).
