Pennsylvania Route 412 (PA 412) is a north–south state route located in Northampton and Bucks counties in southeastern Pennsylvania. Its southern terminus is at PA 611 in the Nockamixon Township community of Harrow. Its northern terminus is at PA 378 in Bethlehem. The route passes through rural areas in northern Bucks County, forming a concurrency with PA 212 in the Springtown area. From there, PA 412 continues into Northampton County and passes through Hellertown before interchanging with Interstate 78 (I-78) and heading into Bethlehem. In Bethlehem, PA 412 passes the former Bethlehem Steel site and runs through the South Side neighborhood. PA 412 was originally part of the 18th-century Durham Road that ran through Bucks County and north into the Lehigh Valley. The route was first designated by 1927 between PA 212 in Springtown and PA 12 in Bethlehem. PA 412 was extended south to U.S. Route 611 (US 611) in Harrow by 1930. The route was realigned through the South Side of Bethlehem in the 1980s. ==Route description== PA 412 begins at an intersection with PA 611 in the community of Harrow in Nockamixon Township, Bucks County, heading northwest on two-lane undivided Durham Road. The road passes through farmland with some homes and businesses, coming to an intersection with the northern terminus of PA 563. The route continues through a mix of farmland and woodland with some development, passing through Bucksville. PA 412 enters Springfield Township and becomes an unnamed road, passing through Gallows Hill. The road winds northwest through more rural areas and comes to an intersection with PA 212. At this point, PA 412 turns west to join PA 212 in a concurrency, heading through forests and fields before passing through the residential community of Springtown as Main Street. The road curves southwest and heads back into rural areas as an unnamed road. PA 412 splits from PA 212 by turning west, passing through farmland and woodland. The route enters Lower Saucon Township in Northampton County, becoming Leithsville Road and running through more rural areas. The road turns north at the community of Leithsville and passes through woodland with homes and commercial establishments. PA 412 enters Hellertown and becomes Main Street, a three-lane road with a center left-turn lane that runs past businesses. The route becomes two lanes again and becomes lined with homes with a few businesses as it continues north through Hellertown. The road becomes the border between Hellertown to the west and Bethlehem to the east as it comes to an interchange with I-78.〔〔 Past this interchange, PA 412 fully enters Bethlehem and becomes Hellertown Road, passing through commercial areas. The route gains a second northbound lane and passes over the Saucon Creek and under a Norfolk Southern railroad spur before turning northwest onto East 4th Street. The road passes between the former Bethlehem Steel plant to the north and a railroad yard to the south, curving west and becoming a three-lane road with one northbound lane and two southbound lanes. PA 412 passes over the railroad spur before turning northwest onto four-lane divided Daly Avenue. The route passes between Sands Casino Resort Bethlehem to the north and residential neighborhoods to the south, curving west. PA 412 passes to the south of more of the former Bethlehem Steel site, turning west onto undivided East 3rd Street, with two northbound lanes and one southbound lane. The route passes through commercial areas, narrowing to two lanes and heading through the downtown area of the South Side neighborhood of Bethlehem. PA 412 intersects an access road to the Hill to Hill Bridge, which carries PA 378 over the Lehigh River to the north, at which point PA 412 turns south onto Brodhead Avenue. A short distance later, the route turns southwest onto Broadway and passes through urban areas of homes and businesses. PA 412 reaches its northern terminus at an intersection with PA 378 known as Five Points.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pennsylvania Route 412」の詳細全文を読む スポンサード リンク
