Pennsylvania Route 663 (PA 663) is a 22.13-mile-long (35.61 km) state highway in Montgomery and Bucks counties in southeast Pennsylvania. Its southern terminus is at PA 100 in Pottstown and its northern terminus is at PA 309 and PA 313 in Quakertown, where it continues eastward as PA 313. Along the way, PA 663 also passes through the town of Pennsburg. It is called John Fries Highway between Pennsburg and Quakertown. It has an interchange with Interstate 476 (I-476, the Northeast Extension of the Pennsylvania Turnpike) at exit 44 west of Quakertown. The route was assigned in 1930, and it has had several realignments since its commissioning, including two major ones.
PA 663 begins at an intersection with PA 100 in the borough of Pottstown in Montgomery County, heading east on four-lane undivided West King Street. The road passes through commercial areas and crosses the Colebrookdale Railroad at-grade and Manatawny Creek. The route becomes two-lane undivided King Street and is lined with residences. PA 663 turns north onto North Charlotte Street and continues past homes, curving to the northeast. The road crosses Mervine Street and becomes the border between Upper Pottsgrove Township to the northwest and Lower Pottsgrove Township to the southeast, running through a mix of residential and commercial areas. The route turns east to fully enter Lower Pottsgrove Township before it curves back to the northeast, again following the border between Upper Pottsgrove Township and Lower Pottsgrove Township past the Keim Street intersection. PA 663 continues through wooded areas with a few homes and enters New Hanover Township. The road runs through more rural areas with some development and comes to the Swamp Pike intersection.
Farther northeast, PA 663 intersects PA 73 and turns east to form a concurrency with that route on Big Road. The road crosses Swamp Creek before PA 663 splits from PA 73 by heading northeast on Layfield Road. The route runs through farmland and woodland with some development. Farther northeast, the road heads into Upper Hanover Township and crosses the Green Lane Reservoir along the Perkiomen Creek. PA 663 heads into the borough of Pennsburg, where it becomes Pottstown Avenue and runs past homes and a few businesses, passing east of the terminus of an East Penn Railroad line. In the center of town, the route intersects PA 29. Past this intersection, the road becomes Quakertown Avenue and passes more development before leaving Pennsburg for Upper Hanover Township again. At this point, the route becomes John Fries Highway and heads through farm fields and woods.
Past the Geryville Pike intersection, PA 663 enters Milford Township in Bucks County and continues through more rural areas. The road passes to the southeast of Spinnerstown and widens into a four-lane divided highway at the Spinnerstown Road/Krammes Road intersection, where it curves to the east. The route becomes undivided and comes to an interchange with I-476 (Pennsylvania Turnpike Northeast Extension). A park and ride lot is located south of the road at this interchange. PA 663 becomes a divided highway again and passes businesses. The route becomes a two-lane undivided road again and continues back into rural areas, where it crosses Allentown Road and Unami Creek. The road passes to the north of Milford Square and runs near some development, heading south of St. Luke's Hospital-Upper Bucks Campus. The route enters Richland Township at the Portzer Road intersection and passes homes, becoming the border between Richland Township to the north and the borough of Quakertown to the south at the Milford Square Pike intersection, with the name becoming West Broad Street. PA 663 heads into commercial areas and fully enters Quakertown, where it widens back into a four-lane divided highway and comes to its northern terminus at an intersection with PA 309. Past this intersection, the road continues east as PA 313.
PA 663 was once part of the Steinsburg and Milford Square Turnpike. The turnpike was chartered in March 1858. When Pennsylvania legislated routes in 1911, what is now PA 663 was not given a number. PA 663 was designated in 1930 to run from in US 422 (High Street) in Pottstown north to PA 73 in New Hanover Township. At this time, the entire length of the route was paved, along with the unnumbered road between PA 73 and Quakertown. In 1936, PA 663 was extended north to an intersection with US 309 (now PA 309) and PA 212 (now PA 313) in Quakertown. The route followed its current alignment between PA 73 and Pennsburg before it followed Quakertown Road and Sleepy Hollow Road to Spinnerstown, where it turned east and followed Spinnerstown Road and Milford Square Pike to Quakertown. By 1967, the southern terminus of PA 663 was rerouted to PA 100 in Pottstown, heading west on King Street. In the 1960s, PA 663 was shifted from Milford Square Pike to a new alignment to the north between the Northeast Extension and Quakertown. After construction began in 1973, a new alignment of PA 663 to the south from Pennsburg to the Northeast Extension opened a year later, with the route moved off Quakertown Road, Sleepy Hollow Road, and Spinnerstown Road.
