## Route description

PA 921 begins at an intersection with PA 74 in the borough of Dover, heading northeast on two-lane undivided Canal Road. The road passes a mix of homes and businesses before turning east and becoming the border between Dover to the north and Dover Township to the south, passing residential subdivisions. The route fully enters Dover Township as it turns northeast into wooded areas of homes before passing a mix of farmland and residences. Upon crossing Bull Road, PA 921 heads into Conewago Township and passes more agricultural areas with some patches of woods and housing. The road intersects PA 297 in the community of Zions View, where it makes a turn to the east and crosses the Little Conewago Creek, becoming the border between East Manchester Township to the north and Manchester Township to the south as it passes under Interstate 83. Immediately after, PA 921 turns northeast into East Manchester Township and passes farm fields.
The road turns southeast onto Zions View Road and passes more areas of agriculture before entering the borough of Manchester and becoming Musser Street. Here, PA 921 passes homes before it turns north to form a concurrency with PA 181 on Main Street. The two routes pass residences and businesses in the center of town before PA 921 splits from PA 181 by heading east on Maple Street. The road passes more residences and continues into the borough of Mount Wolf. Here, PA 921 crosses Norfolk Southern's York Secondary railroad line and turns southeast to reach its eastern terminus at the northern terminus of PA 24.

## History

When Pennsylvania legislated routes in 1911, what is now PA 921 was not given a number. PA 921 was designated in 1928 to run from PA 24 (now PA 181) in Manchester east to Mount Wolf. The western and eastern portions of the route were paved while the middle section was unpaved. By 1930, the entire length of PA 921 between Manchester and Mount Wolf was paved. The unnumbered road between Dover and Manchester was paved in the 1930s. In the 1940s, PA 921 was extended west from Manchester to PA 74 in Dover. PA 24 was extended from east of York to reach its northern terminus at PA 921's eastern terminus in Mount Wolf in the 1970s.
