Middletown is in the heart of Lower Bucks, the most heavily urbanized portion of the County. The Township is situated approximately midway between Philadelphia to the west and Trenton to the east. Middletown is adjacent to the Pennsylvania Turnpike, about 1.5 miles from Exit 351 (old Exit 28) and 2 miles from Exit 358 (old Exit 29). The Township is crossed by major traffic routes, including 1-95, U.S. 1, and PA Route 413, among others. These roads are convenient links to locations across the Delaware Valley and lead directly to the interstate highway system. Eleven municipalities border Middletown. These include the townships of Newtown, Lower Makefield, Falls, Bristol, Bensalem, Lower Southampton and Northampton, and the four boroughs of Langhorne, Langhorne Manor, Penndel and Hulmeville.
