Принц-Эдуард аралындағы 158-ші бағдарламалық жол: Харпер және Леовиль аймақтары

Route 158, officially named Harper Road, and sometimes referred to sectionally as Leoville Road (see below), is a 2 lane collector highway in western Prince County, Prince Edward Island, Canada. It is located 0–4 miles SW of the community of Tignish. Its maximum speed limit is
The highway runs from Route 156 (Palmer Road) to Route 2 (Tignish), the Veteran's Memorial Highway, passing through the communities of Tignish, Harper, Leoville, and Palmer Road. The highway is grossly considered as part of the Tignish district, though some may consider southern portions of the highway to be part of the St. Louis–Miminegash region.

Though the entire highway runs straight from Route 156 (Palmer Road) to Route 2 (Western Road) without any interruptions, the highway is sometimes considered by local residents to be two "separate roads" because of traditional naming and zoning. Since the highway contains the two separate communities of Harper and Leoville, but is entirely officially known as Harper Road, some locals avoid naming the Leoville portion of the highway as being on "Harper Road" because Leoville is seen as distinct from Harper (or Harper Road). Some will thus sometimes (inaccurately) label the Leoville portion of Route 158 as Leoville Road.

Harper Road is a secondary highway in Prince Edward Island, and is one of the busiest secondary highways in the Tignish area. In terms of emergency services, Tignish Fire Department services civic house numbers 1 through 1100 on Harper Road, which is from the Western Road intersection south to the Provost Road intersection. Civic addresses south of there (house numbers 1101–1550) are part of Miminegash Fire Department.
