Sonora's Highway 15 stretches from the U.S.-Mexico border in Nogales to the border with the Mexican state of Sinaloa at Estación Don.

A Mexican transportation official said a long-awaited — and frequently delayed — four-lane interstate should be finished this spring.

Mexico’s current President Andrés Manuel López Obrador and his predecessor Enrique Peña Nieto both have promised to finish that highway, but the expected completion dates have repeatedly come and gone. Once done, the major roadway will provide four high-speed lanes from the Arizona-Sonora border in Nogales all the way to the Sonora-Sinaloa border. And according to federal transportation delegate Eduardo Pacheco, that’s just two to two-and-a-half months out.

“We are just about to finish,” he told Hermosillo broadcaster Uniradio Noticias, adding that the project is 99 percent complete, and most of the remaining work is between Ímuris and Nogales. That includes laying concrete, adding drainage and building walls, he said.
