Delaware Route 273 (DE 273) is a state highway in New Castle County, Delaware. The route runs from Maryland Route 273 (MD 273) at the Maryland border near Newark east to DE 9 and DE 141 in New Castle. The route runs through suburban areas between Newark and New Castle as a four-lane divided highway, passing through Ogletown and Christiana. DE 273 intersects DE 896 in downtown Newark, DE 2/DE 72 on the eastern edge of Newark, DE 4 in Ogletown, Interstate 95 (I-95), DE 7, and DE 1 in Christiana, DE 37 in Pleasantville, and DE 58 and U.S. Route 13 (US 13)/US 40 in Hares Corner. What is now DE 273 was originally built as a state highway in the 1920s and 1930s, with the portion east of Hares Corner becoming a part of US 40, which had crossed the Delaware River on a ferry between New Castle and Pennsville, New Jersey. DE 273 was designated by 1936 to connect the Maryland border near Newark to Hares Corner. In the 1950s, the route was extended to New Castle when US 40 was realigned to the Delaware Memorial Bridge. DE 273 was moved onto new alignments around Christiana in the 1980s and through Ogletown in the 1990s. ==Route description== DE 273 begins at the Maryland border west of Newark, where it continues west into that state as MD 273. From the state line, the route heads southeast on two-lane undivided Nottingham Road, passing through wooded suburban neighborhoods as it enters Newark. DE 273 becomes West Main Street as it approaches the downtown area, intersecting the southbound direction of DE 896, at which point DE 273 forms a concurrency with southbound DE 896. The road crosses CSX's Philadelphia Subdivision and comes to an intersection with New London Road, which runs northwest as northbound DE 896, and South Main Street, which heads southwest as DE 896.〔〔 At this point, DE 273 splits into the one-way pair of West Delaware Avenue eastbound and West Main Street westbound, with eastbound DE 273 briefly following one-way South Main Street southwest to get from West Main Street to West Delaware Avenue. The one-way pair, which carries two lanes in each direction, becomes concurrent with DE 896 in both directions until the South College Avenue intersection. DE 273 runs through the University of Delaware campus and continues through the downtown as East Delaware Avenue eastbound and East Main Street westbound. Farther east, East Delaware Avenue shifts farther to the south of East Main Street, with the one-way streets passing between a residential neighborhood and coming to an intersection with DE 2/DE 72. At this point, eastbound DE 273 turns north to join DE 72 on four-lane divided Library Avenue to rejoin westbound DE 273. Past DE 2/DE 72, DE 273 leaves Newark and heads east on Ogletown Road, a five-lane road with a center left-turn lane that passes through commercial areas, soon becoming a four-lane divided highway. The road continues east and comes to a bridge over Amtrak's Northeast Corridor. The route turns southeast and reaches an interchange with DE 4 in Ogletown. Past this interchange, DE 273 becomes Christiana Road and heads east through suburban residential neighborhoods with some businesses. The road bends southeast again as it comes to an interchange with I-95 (Delaware Turnpike). Following this, the route heads into more commercial areas and becomes the Christiana Bypass to the southwest of the community of Christiana. DE 273 runs south through wooded areas and crosses Old Baltimore Pike before curving east and coming to an intersection with DE 7. A short distance later, the road reaches an interchange with the DE 1 freeway.〔〔 Following this interchange, DE 273 becomes Christiana Road and heads through woods before entering areas of suburban homes and businesses, coming to an intersection with the southern terminus of DE 37 in Pleasantville. The route continues east and intersects the eastern terminus of DE 58 near the Wilmington Airport. A short distance later, the road comes to an intersection with US 13/US 40 in Hares Corner.〔〔 Past this intersection, DE 273 becomes concurrent with DE 9 Truck and turns into two-lane undivided Frenchtown Road, heading east between business parks to the south and farm fields to the north. DE 273 comes to an intersection with DE 9 and DE 141 to the west of New Castle, where the route, along with DE 9 Truck, officially ends. Despite this, DE 273 signage continues east along DE 9 toward New Castle on Delaware Street. Before reaching the New Castle Historic District after a crossing of Norfolk Southern's New Castle Secondary, DE 9/DE 273 makes a left turn onto Ferry Cut Off Street. DE 273's signed eastern terminus is at Sixth Street near the Delaware River, where DE 9 turns northeast on Sixth Street to head toward Wilmington.〔〔 DE 273 has an annual average daily traffic count ranging from a high of 49,566 vehicles at the I-95 interchange to a low of 8,760 vehicles at the western edge of Newark.〔 The portion of DE 273 east of DE 896 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「Delaware Route 273」の詳細全文を読む スポンサード リンク
