The route is a two-lane undivided road that runs through a mix of rural and developed areas to the north of the cities of Allentown and Bethlehem, serving the communities of Balliettsville, Egypt, Cementon, and Northampton.

From this intersection, the route heads southeast on two-lane undivided Bellview Road past housing developments, soon passing under Interstate 476 (Pennsylvania Turnpike Northeast Extension) and crossing Coplay Creek.

The route makes a curve to the east again as it continues through more farmland with scattered residential subdivisions, passing through Balliettsville.

Upon entering Whitehall Township, the road becomes Main Street and passes through Egypt and continues past more homes and reaching the PA 145 junction.

At this point, the name of the road becomes Nor-Bath Boulevard and it passes between a quarry and a lake to the north and industrial areas to the south before entering farmland.

The route continues through agricultural areas with some housing before reaching the PA 987 junction in Franks Corner.

[11] The Seventh Street Pike was built starting in the later part of the 1920s to provide a straight north-south road in Whitehall Township.

Another alignment designated PA 329 branched from the route in Balliettsville and headed southeast along Mauch Chunk Road and 18th Street to US 309/PA 29 and US 309 Byp.
