Arizona and Mexico are joining efforts to further develop a key trade corridor at the border.
The Arizona Department of Transportation says the agency and Mexican transportation officials signed a memorandum of understanding in Mexico City this week, establishing a committee to study how to improve a corridor linked to a port of entry.
The study will focus on identifying priority projects and easing congestion in a corridor along Interstate 19 in Arizona and Highway 15 in Mexico.
Gov. Doug Ducey says the agreement will make the trade corridor one of the most competitive in the global market.
Mexico's Ministry of Communications and Transport has pledged $100,000 toward the first phase of what is expected to be a multiyear study.
Arizona's transportation department is contributing $200,000.
