Route description
PA 463 begins an intersection with PA 63 on the border of Hatfield Township and Towamencin Township in the North Penn Valley region, heading northeast on four-lane undivided Forty Foot Road into Hatfield Township. The road passes through commercial areas and farmland and narrows to two lanes. The route continues into residential areas with a few businesses and enters the borough of Hatfield, where it becomes West Broad Street. In Hatfield, the road continues northeast to the center of town. Here, PA 463 turns to the southeast on South Main Street and passes more residential and commercial development, crossing the Bethlehem Line railroad line that is owned by SEPTA and operated by the Pennsylvania Northeastern Railroad at-grade. The road continues back into Hatfield Township and becomes Cowpath Road. The route crosses SEPTA's Lansdale/Doylestown Line at-grade near the Fortuna station and intersects Broad Street in a commercial area.

Heading past more homes, PA 463 enters Montgomery Township at the Line Street intersection. It reaches the community of Montgomeryville, where PA 463 widens into a four-lane divided highway and intersects PA 309 (Bethlehem Pike) and US 202 Bus. (Doylestown Road) at the Five Points intersection.

Past this intersection, the route takes on the name Horsham Road and passes near more businesses as it narrows into a three-lane road with a center left-turn lane and one travel lane in each direction. After crossing North Wales Road, the route carries five lanes total, with two travel lanes in each direction and a center left-turn lane, as it heads into residential areas. The road passes through commercial areas past the Upper State Road intersection and crosses US 202 and the US 202 Parkway Trail. The route heads across Little Neshaminy Creek before reaching an intersection with Stump Road. Past Stump Road, PA 463 narrows to two lanes total and runs past residential areas and business parks. Farther southeast, the route becomes the border between Horsham Township to the southwest and Montgomery Township to the northeast.

Upon crossing Lower State Road, PA 463 leaves the North Penn Valley region and fully enters Horsham Township, becoming a three-lane road with a center left-turn lane as it heads past housing subdivisions. The route loses the turning lane and continues southeast to PA 152 in the village of Prospectville. At this intersection, PA 463 gains a center left-turn lane again and passes a few businesses before continuing past Deep Meadow Park and Kohler Park and crossing Park Creek. The road intersects Keith Valley Road and passes near Samuel Carpenter Park. At the Babylon Road junction, the route becomes a five-lane road and runs to the northeast of Hatboro-Horsham Senior High School and past business parks before coming to Privet Road. At this point, PA 463 runs past the Horsham Air Guard Station to the northeast and homes and businesses to the southwest. The route reaches the edge of the air station property at the Maple Avenue intersection. PA 463 intersects Dresher Road, where the center left-turn lane ends and the road becomes four lanes, reaching its eastern terminus at PA 611 in the community of Horsham. At the eastern terminus, access from PA 463 to northbound PA 611 is provided by Dresher Road.

History
When Pennsylvania first legislated routes in 1911, present-day PA 463 was not given a number. In 1928, PA 463 was designated onto its current alignment from PA 63 in Hatfield Township to US 611/PA 2 in Horsham. At this time, the route was paved between PA 63 and Hatfield. When first created, PA 463 intersected US 122/US 309/PA 12/PA 52 in Montgomery Township and PA 152 in Horsham Township. By 1930, PA 463 was paved in Horsham Township. At this time, it no longer intersected PA 12 and PA 52 and it now intersected PA 752 in Horsham Township. The remainder of PA 463 was paved by 1940. Also by this time, US 122 became US 202 and PA 463 no longer intersected PA 752, the first of several changes to the routes that intersected PA 463.

In 1968, the US 309 designation that the route intersected in Montgomeryville became PA 309. The route at the eastern terminus of PA 463 changed from US 611 to PA 611 in 1972. Construction began to widen the section of PA 463 between North Wales Road and General Hancock Boulevard into a five-lane road as part of the US 202 parkway project in 2009.  The widening project was completed a year later.
