State Route 1002 (SR 1002), locally known as Tilghman Street and Union Boulevard, is a major long east–west road in the Allentown-Bethlehem-Easton metropolitan area of the U.S. state of Pennsylvania. The majority of the roadway is the former alignment of U.S. Route 22, maintained by the Pennsylvania Department of Transportation as a Quadrant Route, and is not signed except on small white segment markers.〔 Tilghman Street begins at Pennsylvania Route 100 in Fogelsville, though SR 1002 continues west on Main Street (also old US 22) to the intersection of Church Street (SR 3014). It becomes Union Boulevard just east of the bridge over the Lehigh River in Allentown; SR 1002 ends at the interchange with Pennsylvania Route 378 in Bethlehem. Union Boulevard continues over Monocacy Creek, which forms the border between Lehigh and Northampton Counties, and ends in downtown Bethlehem.〔〔(【引用サイトリンク】title=Lehigh County Roads Map )〕 The highway attracts more than the average traffic for roads in the Lehigh Valley. An average of 21,018 vehicles use it in South Whitehall Township and 21,706 in Allentown each day.〔(【引用サイトリンク】title=Interactive Traffic Volume Map )〕 ==History== When the state began taking over state highways through the Sproul Road Bill, signed May 31, 1911,〔(【引用サイトリンク】title=Department of Highways )〕 this system did not include the direct Allentown-Harrisburg route that Interstate 78 and the parallel Tilghman Street now form part of. The main route to Harrisburg, which would soon become the William Penn Highway, left Allentown further south, on Hamilton Boulevard (now Pennsylvania Route 222 and U.S. Route 222); the portion near Allentown was Legislative Route 157 (LR 157). Another route west from Allentown (LR 163, later U.S. Route 309) ran northwest from Allentown via Walbert Avenue to Schnecksville. Travelers could continue via New Tripoli to Lenhartsville, and then along a route approximating the present I-78 to Harrisburg. From Allentown east to downtown Bethlehem, LR 159 used Hanover Avenue and Broad Street. No state highways existed within the city limits of Allentown. The William Penn Highway was organized as an alternative to the Lincoln Highway being parallel to the Pennsylvania Railroad west of Harrisburg. The route's New York Extension, adopted in 1916, passed through Allentown. The state assigned the Pennsylvania Route 3 designation to this road in 1924, and in 1926 it became part of U.S. Route 22.〔(【引用サイトリンク】title=William Penn Highway: US 22 in Pennsylvania )〕 The road west from Allentown, now College Heights Boulevard, Broadway, Tilghman Street, and Main Street, was designated LR 443 in 1925,〔Public Law 191, passed April 8, 1925〕 and soon the entire shortcut between Allentown and Harrisburg was designated Pennsylvania Route 43. ''The New York Times'' was recommending use of this cutoff by early 1931〔 and the American Association of State Highway Officials officially moved US 22 to PA 43 on June 8, 1931. The Pennsylvania Department of Highways moved the William Penn Highway name to match.〔 Tilghman Street and Union Boulevard (then Union Street) were once local streets in Allentown and Bethlehem, with no bridge over the Lehigh River connecting them; Allentown built that bridge in 1929.〔(【引用サイトリンク】publisher=United States Department of Transportation Federal Highway Administration )〕 Prior to 1931, there were no state highways in Allentown or a number of other major cities in the state. However, the state did define paths through these cities for the public; in Allentown, US 22 used Hamilton Street, and PA 43 entered on Liberty Street and turned south on 17th Street to reach Hamilton Street. The Pennsylvania General Assembly passed, on June 22, 1931, a law defining state highways through these cities and changing routes in other cities. LR 443 was defined to use College Heights Boulevard and Tilghman Street to 15th Street, where LR 157 continued along Tilghman Street and Union Boulevard to the Allentown-Bethlehem line. LR 159 was redefined to begin at the same point, continuing on Union Boulevard to Main Street in downtown Bethlehem (and beyond to Easton).〔Public Law 720, No. 262, passed June 22, 1931〕 The newest part of Tilghman Street includes the bridge over Little Cedar Creek in Trexler Park west of Cedar Crest Boulevard, which dates to 1936,〔 and bypasses the older route via Broadway and College Heights Boulevard. Tilghman Street and Union Boulevard became a major long-distance traffic route, and had eight diners as a reminder of this past importance. In addition to US 22, Tilghman Street also carried U.S. Route 309 and Pennsylvania Route 29 between 19th Street and Seventh Street. They were moved from Hamilton Street with US 22 in 1931,〔〔〔 and to a freeway bypass of Allentown in the late 1950s.〔 The Lehigh Valley Thruway, a freeway taking US 22 around Allentown and Bethlehem to the north, was opened on September 21, 1954.〔Matt Assad, The Morning Call, Route 22: Fifty years, one billion cars, September 19, 2004〕 With the opening of these two highways, and the western extension of the Thruway in the late 1950s,〔 no signed Traffic Routes remained on Tilghman Street and Union Boulevard, yet the road was still state maintained. It still carried LR 443, LR 157, and LR 159 through the cities, since the Thruway was assigned a new number — LR 772 — but west of the crossing at Kuhnsville, LR 443 was moved to the freeway, and the old route became LR Old 443, later LR 443 Parallel. The road west of Church Street in Fogelsville, which was also a state highway (LR 39084), was removed from the state highway system in the late 1970s.〔Public Law 1242, No.428, passed September 27, 1978〕 A gap in LR 159 through downtown Bethlehem was created in 1971, at the same time as Washington Avenue and Stefko Boulevard were added to the system as a bypass, with Union Boulevard east of Pennsylvania Route 378 becoming a city street.〔Public Law 640, No. 164, passed December 15, 1974〕 Thus in 1987, when the new Location Referencing System was adopted, only the portion of Tilghman Street and Union Boulevard between Church Street and PA 378 was assigned a new number: State Route 1002. In late October 2012, the Tilghman Street Bridge over the Lehigh River was repaved in order to accommodate construction vehicles for the long-awaited beginning of the American Parkway Bridge project. 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「State Route 1002 (Lehigh County, Pennsylvania)」の詳細全文を読む スポンサード リンク
