Just drove down from British Columbia last week thru Nogales, AZ. I make the trip from Nogales to Chapala in 2 days with an overnight stop in Los Mochis. The Carretera and Autopista (15D) was completely ripped up throughout all of Sonora and most of Sinaloa. 15D was one lane in each direction on one side of the highway, with the other side (2 lanes) closed for maintenance/rebuilding, and switching from one pair to the other pair of lanes every few kilometers. Strongly recommend that you choose a different route. Construction appears like it will continue for months or even years!! NOT safe, and if one accident along the way, highway will likely get closed until wreckage is cleared because not even a shoulder, paved or otherwise, to drive on!! Will be going back the long way thru Laredo.
