 PA 179 begins at an intersection with US 202 in Solebury Township, Bucks County, Pennsylvania, heading east on two-lane undivided Lower York Road through commercial areas. The road crosses into New Hope and becomes Bridge Street as it passes near a shopping center and more businesses. Farther east, the route gains a center left-turn lane and enters more residential surroundings as it passes New Hope-Solebury High School. From this point, PA 179 loses the center left-turn lane and passes more homes. Upon crossing the New Hope and Ivyland Railroad, the route heads into the downtown of New Hope and intersects PA 32. PA 179 continues east to the New Hope-Lambertville Bridge over the Delaware River.
