I always thought the province took control because it lies under the regulation of the Canamex Corridor, established by NAFTA, and therefore the overpasses became a international requirement, so the province decided to fund and build them. However,that might have nothing to do with it.

The CANAMEX corridor is a corridor linking Canada to Mexico through the United States. The corridor was established under the North American Free Trade Agreement.[1] Currently the corridor is defined by a series of highways. However the corridor is also proposed for use by railroads, pipelines and fiber optic telecommunications infrastructure.
The United States portion of the highway was established as a High Priority Corridor. The treaty establishes that the CANAMEX highway will be upgraded to at least 4 lanes along its entire length. In 2008, 84% of the highway in the United States was compliant, 86% of the highway in Mexico was compliant.[3] The Canada portion was completed in 2007.
Two bottlenecks were identified with the Arizona portion of the corridor. The first was the route of U.S. Route 93 across northwestern Arizona, which at the time included a slow windy route over the Hoover Dam. The Hoover Dam Bypass opened in December 2010 resolving this issue.[
