In which Pennsylvania county is the unincorporated community of Gap located?

The unincorporated community of Gap is located in Lancaster County, Pennsylvania.

Gap is a census-designated place and unincorporated community in eastern Lancaster County. Most of it lies in Salisbury Township, although a small portion extends south into neighboring Sadsbury Township. The community sits at a low pass between Mine Ridge and Gap Hill, which explains its simple geographic name.

The settlement developed along the historic Philadelphia–Lancaster Pike, now largely followed by U.S. Route 30. A railroad line was later built through the pass, and the same general right-of-way remains part of Amtrak’s Keystone service. Gap is roughly 16 miles east of Lancaster and about 49 miles west of Philadelphia.

The place is not in York, Berks, or Chester County, though all three are nearby Pennsylvania counties. Gap’s county identity is also distinct from the surrounding township names: Salisbury and Sadsbury are local municipalities, while Lancaster is the county-level answer.
