Mexican authorities are closing the U.S-Sonora border to nonessential travel this holiday weekend, when Arizonans would normally flock to Mexican beach towns like Rocky Point and San Carlos for the Fourth of July.

Starting Saturday, July 4, southbound travelers without essential business in Sonora will be turned away at border checkpoints in Nogales, Agua Prieta, Sonoyta and San Luis Rio Colorado, said Sonora Gov. Claudia Pavlovich’s office. The governor did not specify an end-date for the border closure…

“We are all going to be on alert at this time to prevent them from coming, whether they are Mexicans living in the U.S., Americans or those who want to come to spend the weekend and put a greater burden on us regarding COVID,” Pavlovich said in the release.
