The south end was cut back to a realigned US 6 north of Dickson City in the 1950s. In 1961, the north end was cut back to PA 632, with PA 524 replacing the east-west section running to PA 407. PA 347 was extended south to US 11/PA 307 at Blakely and Green Ridge streets in Dunmore in the 1960s. The south end was moved to SR 2020 at Drinker and Blakely streets and the north end was extended to PA 524 by 1990.

Route description
PA 347 begins at an intersection with SR 6011 in the borough of Dunmore, heading northeast on two-lane undivided North Blakely Street. The road heads past a few businesses before running through residential areas, widening into a four-lane divided highway as it comes to an interchange with I-81/US 6. Past this, the route becomes Oneill Highway, a five-lane road with a center left-turn lane, and runs through commercial areas, passing to the east of the Penn State Worthington Scranton campus. PA 347 crosses into the borough of Throop and splits into a one-way pair following two-lane Cypress Street northbound and two-lane Dunmore Street southbound, with the left lane serving as a left-turn lane. In this area, the road passes homes. The two directions of the route rejoin on two-lane South Valley Avenue and the route continues through residential neighborhoods. PA 347 heads into the borough of Olyphant and it passes more residences before crossing a Delaware–Lackawanna Railroad line and turning northwest onto West Lackawanna Avenue. The road heads through the commercial downtown of Olyphant before crossing the Lackawanna River, at which point it becomes the border between the borough of Blakely to the northeast and the borough of Dickson City to the southwest. The route heads through residential areas, turning west to fully enter Dickson City. Here, PA 347 turns north onto Dundaff Street and crosses into Blakely, becoming Scott Road. The road heads into wooded areas, coming to an interchange with US 6 Bus. The route continues northwest through more woodland with some residences, entering Scott Township. PA 347 becomes Justus Boulevard and heads through rural residential areas, passing through Justus. The road heads north through a mix of farmland and woodland with some homes, running through the community of Millars School. The route intersects PA 632 and continues north through more rural areas a short distance to the east of I-81. PA 347 comes to its northern terminus at an intersection with PA 524, where the road continues north as part of that route.
History
When Pennsylvania first legislated routes in 1911, what is now PA 347 between Dunmore and Blakely was designated as part of Legislative Route 6. With the creation of the U.S. Highway System in 1926, this stretch of road became a part of US 106, which was also designated concurrent with PA 7 and PA 19. At this time, the road was unpaved between Dunmore and Throop and paved between Throop and Blakely. In 1928, US 6 replaced the US 106/PA 7/PA 19 designation along the road between Dunmore and Blakely. PA 347 was designated in 1928 from US 6 in Blakely north to PA 147/PA 247 in Montdale along an unpaved road, following its current alignment before turning northeast along Green Grove Road to Montdale. By 1930, US 6 was shifted off the road between Dunmore and Blakely. In addition, the southern terminus of PA 347 was relocated along Dundaff Street to US 6 in Dickson City while the northern terminus was realigned to PA 407 in Wallsville, following its present alignment before continuing west to PA 407. The entire length of PA 347 was paved in the 1930s. In the 1940s, US 6 was realigned to the Scranton-Carbondale Highway ; however, the southern terminus of PA 347 remained at Main Street in Dickson City. The south end of PA 347 was cut back to US 6 by 1960. In April 1961, the northern terminus of PA 347 was truncated to PA 632, with PA 524 replacing the route between PA 407 and the current northern terminus and the section between PA 632 and PA 524 becoming unnumbered. This change was made as part of the construction of I-81. In the 1960s, PA 347 was realigned and extended south along its present alignment to US 11/PA 307 at the intersection of Blakely and Green Ridge streets in Dunmore. US 11/PA 307 was removed from the southern terminus of PA 347 in the 1980s, leaving the route terminating at an unnumbered road. The southern terminus of PA 347 was cut back to SR 2020 at the intersection of Drinker and Blakely streets by 1990. In addition, the route was extended north along its former alignment from PA 632 to PA 524. Between 2015 and 2017, a slight extension was made at PA 347's southern terminus in Dunmore shifting its end from an intersection with Drinker Street to Green Ridge Street.
