The Arizona Department of Transportation and the Federal Highway Administration have selected the route for a 280-mile stretch of freeway, called Interstate 11, which will run from Nogales to Wickenburg.

The route has long been discussed as a streamlined travel method from Phoenix to Las Vegas, and to enhance the transportation of goods from Mexico into the United States.

The two agencies published a selected corridor, which is 2,000 feet — less than half a mile— wide, where the proposed freeway could run. In later steps, the corridor will be narrowed to a maximum 400-foot-wide alignment, but at this time there is no plan or funding for the next phase of studies, the agencies said in a press release.

The announcement follows the passage of the $1 trillion Infrastructure Investment and Jobs Act, which includes $110 billion of new funds for roads, bridges and other major projects, but Interstate 11 is not specifically mentioned.
