Plans to increase commercial vehicle inspection capacity at the land port of entry along the Mexico border in Douglas, Ariz., are moving along as the U.S. General Services Administration awarded a $274.7-million design-build contract to Hensel Phelps Construction Co. for a commercial port near an existing U.S. Customs and Border Protection facility.

The planned 80-acre facility would increase the number of commercial vehicle inspection lanes from one to four, and the number of commercial inspection docks from 12 to 36, compared to the current Raul Hector Castro Land Port of Entry in Douglas, according to GSA. It would also be large enough to accommodate oversized mining equipment, which is too big for the existing port to accommodate.
