Pennsylvania Route 29 (PA 29) is a north–south state highway that runs through most of eastern Pennsylvania. The route currently exists in two segments, a southern segment and a northern segment. The southern segment runs from U.S. Route 30 (US 30) near Malvern north to Interstate 78 (I-78)/PA 309 near Allentown. The northern segment runs from I-81 in Ashley north to the New York state line near Brookdale, Pennsylvania, where the road becomes New York State Route 7 (NY 7). The southernmost of PA 29's northern segment is a freeway known as the South Cross Valley Expressway. The route was continuous until May 9, 1966 when PA 29 was split into the two segments that exist today. Route description Southern section Chester County The southern section of PA 29 begins at an intersection with US 30 near the borough of Malvern in East Whiteland Township, Chester County, heading north on six-lane divided South Morehall Road. The road passes businesses and office parks, curving northwest and crossing the Chester Valley Trail before coming to an interchange with the US 202 freeway. The route passes to the west of the Penn State Great Valley university campus at the Swedesford Road intersection and then becomes North Morehall Road, narrowing to four lanes and heading to the west of Great Valley Corporate Center. PA 29 runs through wooded areas, crossing Valley Creek before curving north and passing through more of the Great Valley Corporate Center. The road runs between a quarry to the west and a lake and residential development to the east before it comes to a ramp providing access to the Pennsylvania Turnpike (I-76). Past here, the route becomes undivided near more commercial development, crossing into Charlestown Township and then curving northwest and passing under the Pennsylvania Turnpike and an abandoned railroad line before entering Devault. At this point, PA 29 turns north onto two-lane undivided State Road and runs through wooded areas with the abandoned railroad parallel to the east. The road curves northwest and passes to the west of a quarry before continuing through forests. The route turns north and passes through the community of Aldham before it makes a curve to the northeast and crosses the Pickering Creek. PA 29 passes under the abandoned railroad line and enters Schuylkill Township, heading through a mix of woods and fields with some homes parallel to the creek. The road turns east
