U.S. Customs and Border Protection (USCBP) is pilot-testing the operation of a commercial primary inspection booth on Canadian soil. The pilot test is occurring at the Pacific Highway port-of-entry in Blaine, WA. In past years, the Border Policy Research Institute (BPRI) has partnered with the Whatcom Council of Governments (WCOG) to collect extensive datasets at Pacific Highway, including metrics such as the average dwell-time of a truck at a primary booth and the average wait-time in the queue.
