The Mariposa Land Port of Entry is one of the busiest U.S. land ports for vehicle and commercial truck traffic, accommodating more than 1.5 million vehicles per year. This new, $187 million, port-of-entry replaces a 35-year-old facility that had outgrown the needs of the area in both volume of traffic and environmental, inspection and security requirements.

The port maintained operational capacity through about five years of phased construction, during which crews clocked a total of 940,000 worker hours. This was done with no lost time accidents and eight recordables. Project tasks included reworking the bones of the existing structures and facilities while adding 216,000 sq. ft of new construction. The facility received LEED Gold certification and integrated unique elements and poetry to welcome goods and people to the U.S.
