Pennsylvania Route 321 (PA 321) is an state highway located in Elk and McKean counties in the U.S. state of Pennsylvania, maintained by the Pennsylvania Department of Transportation (PennDOT). The southern terminus is at US 219 in the Jones Township community of Wilcox. The northern terminus is at PA 346 in Corydon Township within the Allegheny National Forest. PA 321 heads northwest from Wilcox through rural areas to the borough of Kane, where it forms a brief concurrency with US 6. North of here, the route heads through the national forest and runs along the shore of the Allegheny Reservoir, serving the Red Bridge Recreation Area. PA 321 runs east briefly with PA 59 before winding north through more forest to its northern terminus. A portion of the route along the Allegheny Reservoir is designated as the Longhouse National Scenic Byway, a Pennsylvania Scenic Byway and National Forest Scenic Byway. The road between Wilcox and Kane was designated as part of Legislative Route 97 (LR 97) in 1911 and as a portion of PA 6 in 1924. US 119 became concurrent with PA 6 in 1926 before US 219 replaced both designations on this stretch of road two years later. The road between Kane and Kinzua was built in the late 1920s and became a northern extension of PA 68 in 1935. In 1952, US 219 was relocated off the road between Wilcox and Kane to use a shorter alignment north of Wilcox. Plans were made to construct the Kinzua Dam in 1960, and several new roads would need to be built to accommodate the reservoir including a relocation of PA 68. In 1961, the PA 321 designated was approved for the unnumbered road between Wilcox and Kane and PA 68 between Kane and Kinzua in order to provide an access road to the planned recreation area; signs were posted the following year. Improvements were planned for the road between Wilcox and Kane, through the borough, and to the north of Kane, with a new alignment to be built between Red Bridge and PA 59. The road between Kane and Kinzua was closed to through traffic to allow for construction to occur; the PA 321 designation north of Kane was removed in 1966. Construction began between north of Kane and Red Bridge, including a bridge over an arm of the reservoir, in 1965, while work on the relocation between Red Bridge and PA 59 began in 1967. The road in the Red Bridge area was finished in 1966 while the few miles to the south of there was completed a year later. In 1968, the relocated alignment between Red Bridge and PA 59 was opened along with the road between PA 59 and the New York border near Willow Bay. Construction on the segment north of Kane began in 1970 and was completed he following year. In Kane, PA 321 was relocated from following US 6 through the downtown area to use Hacker Street through the eastern part of the borough. The reconstruction of Hacker Street began in 1972 and was finished a year later. The section of road between East Kane and Kane was rebuilt in 1972. Construction on the section of PA 321 between Wilcox and East Kane, including a bypass of Wilcox, began in 1972. In 1974, PA 321 was extended from US 6 in Kane north to its present terminus at PA 346. The section of road between Wilcox and East Kane was completed in 1975, with a ribbon cutting taking place on July 2. ==Route description== PA 321 begins at an intersection with US 219 in the community of Wilcox in Jones Township, Elk County, heading north on two-lane undivided Buena Vista Highway. The road bypasses the center of Wilcox to the west as it passes through an industrial area. The highway crosses the West Branch Clarion River and curves northwest into forests. The route runs through Dahoga and continues along the eastern border of Allegheny National Forest, with a Buffalo and Pittsburgh Railroad line a short distance to the west of the road. PA 321 enters Wetmore Township in McKean County and becomes Brickyard Road, departing the Allegheny National Forest. The road continues through rural land, passing through Sergeant and East Kane. The route heads into the borough of Kane and becomes Westerberg Way, running through industrial areas as it crosses an abandoned railroad line and comes to an intersection with US 6. Here, PA 321 turns west briefly for a concurrency with US 6 on Biddle Street, immediately turning north-northwest onto Hacker Street, where it is lined with homes. After passing Glenwood Park, the road curves northeast as Kinzua Avenue and leaves Kane for Wetmore Township, becoming Kane-Marshburg Road and heading north-northwest into wooded areas. The route re-enters the Allegheny National Forest and continues northwest, crossing into Hamilton Township and intersecting Longhouse Drive.〔〔 PA 321 comes to a bridge over the Kinzua Creek arm of the Allegheny Reservoir near the Red Bridge Recreation Area, which contains a picnic area, a campground, and a bank fishing area.〔〔(【引用サイトリンク】publisher=Allegheny National Forest )〕 From here, the highway follows the northeastern shore of the reservoir, passing through Dunkle Corners. The road turns to the east and runs along the south shore of Chappel Bay, soon heading away from the reservoir and turning northeast. The route continues into Corydon Township and reaches an intersection with PA 59 near the Bradford Ranger Station.〔〔 At this point, PA 321 turns east for a concurrency with PA 59 and the name remains Kane-Marshburg Road. The road leaves the national forest and heads through the community of Klondike before PA 321 splits to the northwest onto Sugar Run Road in Lafayette Township. The road crosses back into Corydon Township and runs through more of the Allegheny National Forest. The route passes to the north of a section of the Allegheny Reservoir again and turns to the northeast.〔〔 PA 321 winds north and serves the Tracy Ridge Trailhead, which consists of a campground and hiking trails leading to the reservoir.〔〔(【引用サイトリンク】publisher=Allegheny National Forest )〕 The route comes to its northern terminus at PA 346 a short distance south of the New York border.〔 The portion of PA 321 between Longhouse Drive and PA 59 is part of the Longhouse National Scenic Byway, a Pennsylvania Scenic Byway and National Forest Scenic Byway that encircles the Kinzua Creek arm of the Allegheny Reservoir and serves multiple recreational areas.〔(【引用サイトリンク】title=Longhouse National )〕〔(【引用サイトリンク】publisher=Allegheny National Forest )〕 In 2013, PA 321 had an annual average daily traffic count ranging from a high of 6,600 vehicles along the US 6 concurrency in Kane to a low of 100 vehicles between PA 59 and PA 346. The portion of PA 321 that is concurrent with US 6 is part of the National Highway System. 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 321」の詳細全文を読む スポンサード リンク
