Delaware Route 7 (DE 7) is a two- to four-lane north–south highway in New Castle County, Delaware that connects U.S. Route 13 (US 13) and DE 72 near Delaware City to the Pennsylvania border near Hockessin, where it continues into Pennsylvania as State Route 3013 (SR 3013), intersecting Pennsylvania Route 41 (PA 41) at an interchange. Between Delaware City and Christiana, DE 7 runs to the west of the DE 1 freeway through suburban areas, passing through Bear. By the Christiana Mall, DE 7 joins the DE 1 freeway and comes to an interchange with Interstate 95 (I-95) before the DE 1 freeway ends at the DE 58 interchange. After the freeway segment, DE 7 continues north as a surface road concurrent with DE 4 through Stanton. From Stanton to the Pennsylvania border, DE 7 heads northwest through suburban areas, passing through Pike Creek. What is now DE 7 was built as a state highway during the 1920s and 1930s. By 1936, the route was designated to run along its present alignment between US 13 near Red Lion, Delaware and the Pennsylvania border. From the 1950s to the 1970s, DE 7 became a divided highway between Christiana and Milltown Road. With the construction of the DE 1 freeway in the 1990s, DE 7 was shifted to a portion of the freeway near the Christiana Mall. The route was also extended south to an intersection with US 13 and DE 72 as a result of the relocation of US 13 onto a portion of the freeway. The road also became a divided highway between Milltown Road and DE 72 in the 1990s. In 1999, an interchange was built at DE 58 as a result of a northward extension of DE 1 along DE 7. The interchange with I-95 was reconstructed to include flyover ramps in 2013. ==Route description== DE 7 begins at an intersection with US 13 and DE 72 to the west of Delaware City, where the road continues south as part of US 13. From the southern terminus, the route heads north on four-lane divided South Dupont Highway. The road runs through farmland and crosses Norfolk Southern's Reybold Running Track railroad line before passing under the US 13/DE 1 freeway. After this, DE 7 narrows into a two-lane undivided road called Bear-Corbitt Road, with the former alignment of Dupont Highway branching off to the northeast. The route continues north through woodland and homes, reaching an intersection with DE 71 in Red Lion. The road crosses Norfolk Southern's New Castle Secondary railroad line and heads into Bear. Here, DE 7 widens into a four-lane divided highway as it enters commercial areas and intersects US 40.〔〔 After this intersection, the route becomes Bear-Christiana Road and passes through suburban residential development with some farm fields. Farther north, DE 7 narrows into a two-lane undivided road. The highway comes to an intersection with DE 273, where it is briefly a four-lane divided highway. Following this, DE 7 becomes East Main Street and narrows into a two-lane undivided road, heading through woods and curving to the northwest as it crosses Christina River. The route enters Christiana and passes homes, intersecting Old Baltimore Pike. At this point, DE 7 turns north onto North Old Baltimore Pike, with the name changing to Stanton-Christiana Road. The route turns east onto a four-lane divided highway and comes to an interchange with the DE 1 freeway southwest of the Christiana Mall, a super-regional shopping mall that is the largest in Delaware. At this point, DE 7 heads north concurrent with DE 1 on a four-lane freeway. The freeway comes to a southbound exit and northbound entrance that serves the Christiana Mall to the east. DE 1/DE 7 continues to a modified cloverleaf interchange with I-95 (Delaware Turnpike). The road continues through more commercial areas and interchanges with DE 58, at which point the freeway segment and DE 1 ends. Past DE 58, DE 7 continues north at-grade as six-lane divided Stanton-Christiana Road, heading to the west of the Stanton Campus of Delaware Technical Community College before intersecting DE 4. At this point DE 4 turns north for a concurrency with DE 7, passing through wooded areas with nearby development and over Amtrak's Northeast Corridor railroad line and White Clay Creek. The road heads to the east of Delaware Park Racetrack, a thoroughbred horse racetrack and casino, and curves northeast to enter Stanton. At this point the two routes continue into a commercial area and split into the one-way pair of Mitch Road eastbound and Main Street westbound.〔〔 DE 7 splits from DE 4 by heading northwest on four-lane divided Limestone Road. The road runs through suburban residential neighborhoods, coming to a bridge over CSX's Philadelphia Subdivision railroad line. The route continues into business areas and comes to an intersection with DE 2. Past this intersection, DE 7 heads into residential and commercial areas and becomes a four-lane undivided road. The route becomes a divided highway again as it comes to the Milltown Road intersection and enters the Pike Creek area. The road curves west before turning northwest again and running to the southwest of Goldey Beacom College, a private non-profit college. DE 7 turns to the north and comes to an intersection with the northern terminus of DE 72.〔〔 Following this, the road continues through suburban development. At the intersection with Little Baltimore Road/Brackenville Road, the route curves to the northwest and narrows to a three-lane undivided road with one northbound lane and two southbound lanes, heading into the Hockessin area. DE 7 becomes a two-lane divided highway as it intersects Valley Road. Past this, the route becomes a two-lane undivided road that runs through fields and residential areas. DE 7 reaches its northern terminus at the Pennsylvania border, where Limestone Road continues north into that state as SR 3013, heading to an interchange with PA 41.〔〔 DE 7 has an annual average daily traffic count ranging from a high of 65,874 vehicles at the south end of the DE 4 concurrency to a low of 3,777 vehicles at the Old Baltimore Pike intersection.〔 The portion of DE 7 from the south end of the DE 1 concurrency to the Pennsylvania border 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 7」の詳細全文を読む スポンサード リンク
