Dauphin County, Pennsylvania
Dauphin County holds Pennsylvania's capital, with Harrisburg on the east bank of the Susquehanna, Hershey just east in Derry Township, and suburban townships like Lower Paxton between. State government, Penn State Health's Hershey Medical Center, and warehouse demand where I-81, I-83, and the Turnpike meet drive the market, with the Rutherford intermodal yard making industrial siting a rail-and-highway access question.
