PA 8 effectively join to become Parade Street, which continues north to Front Street, just south of the Bayfront Parkway. History PA 8 was first signed in 1926 from West Virginia to Erie. South of Pittsburgh, PA 8 followed the current U.S. Route 19 alignment from the West Virginia state line to Canonsburg, as well as the present Pennsylvania Route 50 alignment from Bridgeville to Crafton. The West Virginia – Pittsburgh segment was decommissioned in 1930. In 1934, construction began on PA 8 between the Allegheny–Butler county line and Three Degree Road. This segment opened in 1935. Later, in 1958, construction commenced on the segment from Grant Avenue to Pennsylvania Route 28 in Etna. In that same year, the route was widened and a median was installed from Franklin to Reno. The Grant Avenue – PA 28 segment was completed the following year. In 1961, PA 8 from the end of the Richard C. Frame Memorial Highway at Interstate 80 to Franklin was upgraded with a median, and, in 1968, the section from Reno to Oil City had a median installed as well. In 1973, construction began on the section of expressway from Pennsylvania Route 308 in Pearl to the northern end of the present expressway south of Franklin in Venango County. That same year, the southern terminus of PA 8 was moved from West Carson Street in Pittsburgh to Pennsylvania Route 28 in Etna. In 1974, construction began on the remainder of the expressway from the present southern end at Wesley to PA 308. The highway was completed in 1976. In 1977, the southern terminus was moved to its current location from PA 28 in Etna. In 1979, the route was realigned onto what was then PA 8 Bypass (Main Street) to bypass downtown Oil City. PA 8 Bypass, initially signed in 1941, was decommissioned while the former routing in PA 8 in Oil City became Pennsylvania Route 8 Business.
