Westmoreland County, Pennsylvania
Westmoreland County stretches east of Pittsburgh from the Norwin and Penn-Trafford suburbs to the Laurel Highlands ridges, anchored by Greensburg, Latrobe, Murrysville and New Kensington. Logistics and advanced manufacturing cluster at the Pennsylvania Turnpike and I-70 interchanges around New Stanton and Irwin, while new subdivisions fill Hempfield, North Huntingdon and Murrysville; abandoned deep-mine workings underlie parts of the county and constrain what can be built.
