TUCSON — Preparations to begin installing 30-foot steel bollards through pristine mountain wilderness along the Arizona-Mexico border south of Sierra Vista will begin as early as Monday, according to conservationists critical of border wall construction in protected federal lands.
U.S. Customs and Border Protection announced Thursday they would close access starting on July 13 to a popular hiking trail located in the Coronado National Memorial in southern Arizona in order to begin pre-construction activities, Matthew Nelson said.
