In an age when algorithms feed consumer demands, the Lehigh Valley has become the East Coast’s supply-chain empire for transporting one-click goods on interstate highways. Covering 726 square miles of suburbs and rural townships in Lehigh and Northampton Counties—centered on the cities of Allentown, Bethlehem, and Easton—the Valley adjoins metro New York and Philadelphia and stands within one truck shift of 100 million people. As e-commerce expanded over the past decade—and then accelerated dramatically amid the pandemic—the Valley transformed into prime territory for retailers like Amazon and Walmart but also for third-party logistics: the outsourced assembly and storage of companies’ products in warehouses, often called “fulfillment” centers, and their distribution through freight services.
