 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 202 Parkway project in 2009. The widening project was completed a year later.
