Route description
York County
PA 74 begins at the Maryland border in Peach Bottom Township in York County, where the road continues south into that state as MD 165. From the state line, the route heads north as two-lane undivided Delta Road, passing through fields and woods with commercial development as it bypasses the borough of Delta to the west. The road curves northeast and then north and intersects the eastern terminus of PA 851 and Broad Street at a roundabout. PA 74 continues north through a mix of farmland and woodland with some homes, curving to the northwest and crossing the Muddy Creek into Lower Chanceford Township. The route turns west to remain along Delta Road and curves northwest through more agricultural areas with occasional residences. The road intersects the western terminus of PA 372 before it passes through the communities of Sunnyburn and Kyleville. Farther northwest, PA 74 reaches the community of Airville, where it intersects PA 425 and forms a concurrency with that route. The two routes curve west and pass residences and businesses before PA 425 splits to the southwest. PA 74 continues northwest through farmland with some wooded areas and homes. The route enters Chanceford Township and passes through the community of Collinsville, where it heads near homes before running past farms and a few businesses. The road curves to the west and heads through the community of Brogue as it runs through agricultural areas with some development. PA 74 runs west-northwest through more rural land and passes through the community of Keys before it crosses into Windsor Township. Here, residential development along the route increases as it continues near more farms with some woods, passing through the community of Petersburg and curving to the west.
PA 74 becomes the border between Windsor Township to the north and the borough of Red Lion to the south before it fully enters Red Lion and becomes East Broadway, passing through residential areas. The road heads past more homes and a few businesses before it reaches the downtown area of Red Lion and comes to an intersection with PA 24. At this intersection, the route turns southwest and becomes West Broadway, heading past residences and curving to the west. PA 74 leaves Red Lion for York Township and gains a center left-turn lane as it passes businesses, turning northwest and becoming East Main Street. The road narrows to two lanes and passes through residential areas as it enters the borough of Dallastown. The route curves west and runs past homes and some businesses, reaching an intersection with the eastern terminus of PA 214. PA 74 passes through the downtown area of Dallastown, with the name changing to West Main Street after crossing Walnut Street. The road passes more homes and turns to the northwest before it leaves Dallastown for York Township and turns to the west, becoming South Queen Street. The route passes fields to the north and residential areas to the south before it runs past businesses. PA 74 makes a turn to the north-northwest and gains a center left-turn lane, heading through more commercial areas and coming to an intersection with the eastern terminus of PA 182. Following this intersection, the road becomes two lanes again and passes through the community of Spry, running north through residential areas with some businesses. Farther north, the route becomes a three-lane road with a center left-turn lane as it passes more suburban development. PA 74 heads past businesses and becomes a four-lane divided highway as it passes west of the York County School of Technology, turning northwest and coming to a partial cloverleaf interchange with I-83.
