HOUSTON — The Department of Homeland Security has issued another waiver of environmental laws to build new border barriers in South Texas, this time for roughly 17 miles (27 kilometers) cutting through the National Butterfly Center and other sensitive areas.

DHS posted a waiver Wednesday that lists six sections where it plans to build “physical barriers and roads” in the Rio Grande Valley at the southernmost point of Texas. It follows another waiver posted Tuesday to build new gates to seal gaps in existing fencing, as the government moves forward with plans to fulfill President Donald Trump’s signature campaign pledge to build a border wall.
