PA 318 begins at the Ohio border in Shenango Township, where the road continues west into that state as SR 304. From the state line, the route heads east on two-lane undivided Hubbard-Middlesex Road, passing through areas of farms and woods with some homes. PA 318 reaches an intersection with PA 718 and continues through more forested areas with residences. The route heads into West Middlesex and becomes Main Street, crossing the Shenango River into residential and commercial areas. In the center of town, the road crosses PA 18. PA 318 continues past more homes prior to heading back into Shenango Township, where it becomes Mercer West Middlesex Road. The route heads east-northeast through rural areas of residences, reaching a partial interchange with I-376 that has access to and from the northbound direction.^[1][2]
