The agency, in conjunction with the Army Corps of Engineers, gave the multimillion-dollar job in the Border Patrol's Rio Grande Valley Sector to SLSCO, CBP said in a news release.
Work on the project, also known by CBP as RGV-03, is expected to kick off in February, the agency said.
Among the anticipated work is the building and set up "of tactical infrastructure," which includes "a reinforced concrete levee wall to the height of the existing levee, 18 feet tall steel bollards installed on top of the concrete wall, and vegetation removal along a 150 foot enforcement zone throughout the approximately six miles of levee wall system," the news release said.
The area will also be equipped with detection technology and video surveillance, the agency said.
The Rio Grande Valley Sector has "high illegal cross border activity," according to CBP.
"Once constructed, this levee wall system will serve as a persistent impediment to transnational criminal organizations, while still allowing river access for property owners, other federal/state/local officials, local emergency responders, and USBP," the agency said.
