History
The road from Upper Strasburg to Fannettsburg and on to Burnt Cabins was built circa 1790 and for many years formed part of the main road from Philadelphia to Pittsburgh. The road is now part of SR 4004 and was known as Three Mountain Road or Horse Valley Road but is generally known as Upper Strasburg Road now.

The town was laid out in 1789 by Dewalt Keefer and serviced Conestoga wagons and travelers crossing the mountains. The early post office, established by 1797, was originally known simply as Strasburg, but the name was changed to Upper Strasburg by 1830 to distinguish it from towns in eastern Pennsylvania.

In 1873, the town had three churches, "one hotel, one steam tannery, one sawmill, two stores, two blacksmith, two shoe-maker, two cabinet-maker, one tailor and one saddler shops, and two hundred ninety-three inhabitants."
