PA 844 is a two-lane undivided road that passes through rural areas in western Washington County, serving West Middletown.

From the state line, the route heads east on two-lane undivided Washington Pike, passing through agricultural areas with some woods and homes.

The route continues east into more forested areas with some residences, heading into Hopewell Township and becoming Jefferson Avenue.

Upon crossing back into Hopewell Township, the route becomes Jefferson Avenue again and runs through a mix of farms and woods before heading southeast into open agricultural areas.

The route passes homes and a few businesses before heading into industrial areas and crossing the Chartiers Creek.

[10] In September 1964, the western terminus of PA 31 was cut back to West Newton in order to avoid intersecting I-70 at multiple locations; the state only wanted state routes to intersect an Interstate highway once to avoid motorist confusion.
