Lumper services in San Antonio

San Antonio sits at the crossing of two national lanes: I-35, the Laredo to Dallas corridor that carries the country's heaviest truck volume with Mexico, and I-10 running east to Houston and west to El Paso. I-37 drops south to the Port of Corpus Christi, and Loop 1604 ties the outer warehouse ring together. Union Pacific operates its San Antonio intermodal facility on the east side, and East Kelly Railport at Port San Antonio, the redeveloped Kelly Air Force Base, provides rail served warehouse and transload space on the southwest side.

Distribution centers cluster northeast along I-35 through Selma, Schertz, Cibolo, New Braunfels and San Marcos, in parks such as Schertz's Enterprise Industrial Park and Tri-County Business and Industrial Park, where Amazon and Walmart operate fulfillment and distribution buildings. H-E-B is headquartered in San Antonio and runs grocery distribution in the market, which keeps refrigerated and frozen dock work steady year round. On the south side, Toyota Motor Manufacturing Texas builds full size pickups alongside an on site supplier park, and Navistar assembles trucks nearby, so parts unloading and sequenced inbound receiving sit next to retail freight.

Demand for dock labor follows those patterns. Trailers crossing at Laredo often arrive floor loaded and mixed, which is where third party unloading and transload crews earn their keep. Rio Grande Valley citrus, onions and melons move north on I-35 in the spring per USDA Agricultural Marketing Service shipping point reports, and retail import volume builds through late summer into the holiday season.
