I wrote a road report in Dec about how bad Mex15 was and no one wanted to believe me. 15 between Mazatlan and Arizona is the worst I have ever seen it. The most dangerous sections are the areas where traffic is routed into the same side of the highway (both directions of traffic in either northbound or southbound lanes) with oncoming traffic so there is not another lane to move to as suggested. Repairs & replacements are being made but not at a rate fast enough to keep up with damage. It will be just as bad if not worst next year. I will not be taking the Pacific Coastal route anytime in the future but will instead go inland and come down the highlands of Mexico. Better roads and cheaper tolls!
