U.S. Customs and Border Protection officers have started construction to replace fencing at the U.S.-Mexico border in downtown Calexico, Calif., with a 30-foot-high, bollard-style wall, according to a press release issued Wednesday.

The 2.25-mile project will stretch from the Calexico West Port of Entry to beyond the Gran Plaza Outlets and includes approximately 2.25 miles of all-weather roads.
