At North Wales Road, PA 63 again becomes Welsh Road and passes several businesses as a four-lane divided road. The route becomes a two-lane undivided road again as it passes between business parks to the northeast and farms and woods to the southwest ahead of a junction with US 202 Bus. (Dekalb Pike). Upon intersecting the US 202 parkway and the southern terminus of the US 202 Parkway Trail, PA 63 forms the border between Montgomery Township to the northeast and Lower Gwynedd Township to the southwest. The road passes through a mix of residential and commercial development, widening into a three-lane road with two westbound lanes and one eastbound lane. PA 63 leaves the North Penn Valley region as it becomes the border between Horsham Township and Lower Gwynedd Township and crosses PA 309 (Bethlehem Pike), with jughandles controlling the movements from PA 309 to PA 63.
