U.S. Route 13 Alternate (Dover, Delaware)

U.S. Route 13 (US 13) runs along the Atlantic coastline for over , passing through five states. Along its route, it possessed numerous special routes, which are all loops off the mainline US 13. At present, there are at least fifteen special routes in existence: two in North Carolina, five in Virginia, two in Maryland, four in Delaware, and two in Pennsylvania. Seven others have existed in the past, but have been deleted.

U.S. Route 13 Business is a business route of U.S. Route 13, passing through Bethel in the state of North Carolina. It is entirely overlapped with North Carolina Highway 11 Business. The route branches from US 13 just south of the town and follows South Main Street through the town, intersecting US 64 Alternate within. It rejoins US 13 just south of its interchange with US 64.

Windsor, NC business loop

U.S. Route 13 Business is a business route of U.S. Route 13 serving Windsor, North Carolina. It begins by following US 17 off the concurrency with US 13 south of the town, but leaves US 17 at the very next intersection, following South Granville Street. It then turns onto West Granville Street, where it follows NC 308, and then north on North King Street, leaving behind NC 308. US 13 Business continues north along King Street until it rejoins US 13 north of the town.

Suffolk, VA business loop

U.S. Route 13 Business is a business route of U.S. Route 13 serving the City of Suffolk in the state of Virginia. It consists of the original routing of the highway before mainline US 13 was rerouted onto a freeway bypass to the west and north of the city. It begins near Suffolk Municipal Airport, where US 13 leaves the roadway at a trumpet interchange, travelling west, while US 13 Business continues north on Carolina Road concurrent with Virginia State Route 32. As it travels deeper into the city, it intersects Washington Street, which carries Virginia State Route 337, and becomes concurrent with Virginia State Route 10. The three routes follow Main Street north until it meets the business routes of U.S. Route 58 and U.S. Route 460. Here, US 13 Business joins the two business routes and heads east on Constance Road. The name changes to Portsmouth Boulevard and US 13 Bus./US 58 Bus./US 460 Bus. cross VA 337. The three-route overlap of business routes rejoin their mainline route, US 13/ 58/460, at a directional interchange (with no access to the southbound/westbound carriageway from the northbound business route) and resumes toward Norfolk.

Major intersections

Cheriton, VA business loop

Major intersections

Onley–Accomac, VA business loop

U.S. Route 13 Business is a business route of U.S. Route 13 serving Onley, Tasley, and Accomac in the state of Virginia, weaving across the parent US 13 several times. It begins in Onley in the south with an intersection with US 13, leaving the mainline route to the east and following Coastal Avenue. It closely parallels a railroad alignment as both of them pass under the mainline US 13 with no interchange, now following the route to its west. SR 650 intersects that route just before it curves to the northeast, meeting SR 316 (Greenbush Avenue) and SR 126 (Fairgrounds Road) at a roundabout. US 13 Business heads east here and takes on the name Tasley Road as it passes through Tasley. Tasley Road carries US 13 Business back towards its parent, intersecting it, and continuing across as it enters Accomac on Front Street. Front Street eventually expands into a four-lane boulevard just before it rejoins mainline US 13, the southbound lanes intersecting with the north bound merging into it as a ramp.

Major intersections

Pocomoke City, MD business loop

U.S. Route 13 Business is a 3.99-kilometre (2.48-mi) business route of U.S. Route 13 that passes through Pocomoke City in Worcester and Somerset Counties in Maryland.

The route begins south of Pocomoke City; US 13's four-lane divided mainline curves away to the right around the town, while US 13 Business continues straight ahead as a two-lane town street.

After intersecting MD 366 the route connects with the original southern terminus of US 113, the latter having been rolled back to terminate at mainline US 13. For a time, the marooned segment was part of MD 250, but is now designated MD 250A. Continuing north the route heads towards the city waterfront and business district, passing through a pair of intersections with traffic lights permanently set to "flash" mode due to lack of traffic.

The route soon reaches the Pocomoke River, crossing it on a drawbridge that was first constructed in the 1920s, reconstructed in the 1990s, and continues in active service today. After crossing the river the route heads out of town into rural surroundings before terminating on US 13 at the southern terminus of MD 364.

The route was originally created as a segment of Maryland Route 675 by 1975, when the four-lane divided Ocean Highway opened around the eastern and northern edges of the town for US 13, allowing through traffic to avoid congested inner-city streets. The road was eventually designated US 13 Business.

Bridgeville, DE business loop

U.S. Route 13 Business (US 13 Bus.) is a business route of US 13 that passes through the town of Bridgeville in Sussex County, Delaware. The business route begins at an intersection with US 13 and DE 404 south of Bridgeville, where it heads west concurrent with DE 404 Bus. as four-lane divided South Main Street. The road immediately curves to the north as it passes to the west of businesses, narrowing into a two-lane undivided road. The route heads north-northwest through farmland before heading into Bridgeville, where it passes homes. In the center of town, DE 404 Bus. splits from US 13 Bus. by heading to the west. US 13 Bus. becomes North Main Street and curves to the north-northeast, leaving Bridgeville and heading through farmland with some development. The business route has a junction with Redden Road before it reaches its northern terminus at an intersection with US 13/DE 404 only accessible to and from the southbound lanes of US 13. US 13 Bus. has an annual average daily traffic count ranging from a high of 6,171 vehicles at the north end of the DE 404 Bus. concurrency to a low of 3,429 vehicles at the northern border of Bridgeville. None of US 13 Bus. is part of the National Highway System.

The route was originally built as a state highway south of Bridgeville by 1920 and north of Bridgeville by 1924, and received the US 13 designation in 1926. In 1952, US 13 was rerouted to bypass Bridgeville to the east on a new divided highway. The former alignment through Bridgeville became US 13 Alt. by 1957. US 13 Bus. was established in 1970, replacing the previous US 13 Alt. designation. In June 2007, a $15 million project began that realigned the intersection at the southern terminus with US 13 and DE 404 from a skewed intersection to a perpendicular intersection and built service roads on both sides of US 13. The project was intended to improve safety at the intersection, which saw a high accident rate due to its design. Work on the project was completed on May 21, 2009, with DelDOT secretary Carolann Wicks and President of Commissioners for the Town of Bridgeville William Jefferson in attendance at a ceremony.

Delmar, DE alternate route

U.S. Route 13 Alternate (US 13 Alt.) was a alternate route extending from US 13 in Delmar, Maryland to Hearne's Mill near Seaford, Delaware. US 13 Alt. began at US 13 south of Delmar in Wicomico County, Maryland, heading northwest into the town on two-lane undivided Bi State Boulevard. The road turned north and came to an intersection with MD 455, at which point it crossed the state line and entered Delmar in Sussex County, Delaware. The route continued north before it left Delmar and headed through rural areas, with a Pennsylvania Railroad line a short distance to the west and US 13 to the east. Farther north, US 13 Alt. entered Laurel, where it became Central Avenue. In Laurel, the route intersected DE 24 and crossed Broad Creek on a drawbridge. The road curved to the northwest and left the town and continued through rural land along Seaford Road, with the railroad tracks to the west and US 13 to the east. The route entered the town of Blades, where it headed north on and reached a junction with DE 20 at High Street. At this point, DE 20 turned north for a concurrency with US 13 Alt., and the two routes continued north, crossing the Nanticoke River on a drawbridge. Here, the road entered the city of Seaford and became Front Street, running north. On the northern edge of Seaford, DE 20 split from US 13 Alt. by turning west onto Stein Highway. From this point, US 13 Alt. left Seaford and became Bridgeville Highway, heading northeast through rural areas to its northern terminus at an intersection with US 13 at Hearne's Mill.

US 13 Alt. was designated in 1954 following the completion of a new divided highway alignment of US 13 between south of Delmar, Maryland and north of Seaford, Delaware. The route was decommissioned in 1957. By 1983, the portion of the former route in Maryland was designated as a section of MD 675. The former route in Delaware is state-maintained and is designated as Road 13. Despite the fact that the road has been decommissioned, locals in Wicomico and Sussex counties still refer to the route as "Alternate 13" or "U.S. Route 13A".

Major intersections

Wilmington, DE alternate route

U.S. Route 13 Alternate (US 13 Alt.) was an alternate route of US 13 located in the city of Wilmington in the state of Delaware. The route served as an eastern bypass of the city. US 13 Alt. began at an intersection with US 13/US 202 at the southern edge of the city of Wilmington, heading northeast on Heald Street. The route crossed a Reading Railroad line at-grade before it curved to the north-northeast and came to a bridge over a Penn Central Railroad line. US 13 Alt. came to an intersection with the northern terminus of DE 9 before it reached Christiana Avenue, where it turned northwest and crossed over the Christina River on a drawbridge. At this point, the alternate route became 4th Street and passed under a Penn Central Railroad line before it turned northeast onto the one-way pair of Church Street northbound and Spruce Street southbound. US 13 Alt. ran through the eastern portion of the city before both directions rejoined at 11th Street. The route headed northeast and passed over the Brandywine Creek, becoming a divided highway called Northeast Boulevard that ran through more of Wilmington. The road curved east and left Wilmington, becoming Governor Printz Boulevard and passing through the community of Edgemoor. Here, US 13 Alt. turned northeast and ran parallel to a Penn Central Railroad line and the Delaware River, both to the east of the route. The road continued past Holly Oak before it reached Claymont. Here, US 13 Alt. turned northwest and came to its northern terminus at an intersection with US 13.

Plans were made in 1918 for a bypass to the east of downtown Wilmington for through traffic, avoiding Market Street. The bypass would utilize Heald Street, Church and Spruce streets, and would construct Northeast Boulevard heading northeast from the Eleventh Street Bridge. The bypass was needed as Philadelphia Pike had steep grades that were difficult for trucks at the time. In 1934, the state highway department began work on this bypass. Among them was the improvement of Church and Spruce streets by widening and paving them. In addition, the Northeast Boulevard was built, running from the Eleventh Street Bridge over the Brandywine Creek northeast to Edgemoor Road in Edgemoor. Construction began this year on an extension of the road northeast to Holly Oak. The following year, the Northeast Boulevard was completed between Edgemoor and Holly Oak. The construction of the Northeast Boulevard led to increased residential and industrial development along the route. In the later part of 1936, construction began on the portion of the Wilmington bypass along Heald Street along with Northeast Boulevard (renamed Governor Printz Boulevard) between Holly Oak and Claymont. Both of these projects were finished in fall 1937 and completed a bypass of the portion of US 13 through Wilmington. This bypass route was designated as US 13 Alt. in 1939. In 1939, construction was authorized to widen Governor Printz Boulevard into a divided highway. The widening of the road to a divided highway was completed in 1940. In 1942, a bridge was completed on Heald Street that eliminated the grade crossing with a Pennsylvania Railroad line. US 13 Alt. was widened to four lanes between 11th Street and 30th Street in Wilmington in 1956. In 1970, US 13 was rerouted to bypass downtown Wilmington on the US 13 Alt. alignment while US 13 Bus. was designated onto the former US 13 alignment from the southern border of Wilmington to Claymont.

Philadelphia, PA bypass

U.S. Route 13 Bypass (US 13 Byp.) was a bypass of a portion of US 13 in Philadelphia, Pennsylvania. It split from US 13 in Darby, Delaware County. The route headed north on Main Street before becoming Lansdowne Avenue and running through Yeadon, Lansdowne, and Upper Darby Township. In Llanerch, US 13 Byp. turned northeast to form a concurrency with US 1 on Township Line Road and crossing PA 3. The two routes continued northeast and became City Avenue, forming the border between Montgomery County to the northwest and Philadelphia to the southeast. Along City Avenue, the bypass route intersected US 30 Byp. (Haverford Road/Avenue), US 30, and PA 23 (Conshohocken State Road/Conshohocken Avenue). At an interchange with I-80S, US 1 split from US 13 Byp. and US 13 Byp. crossed the Schuylkill River and fully entered Philadelphia. Here, the route came to an interchange with US 422 ( Ridge Avenue) and Lincoln Drive and ran east along East River Drive to reach its northern terminus at an intersection with US 1/US 13 (Hunting Park Avenue) in the Hunting Park section of the city. US 13 Byp. was first designated by 1940, where it followed Main Street and Lansdowne Avenue to Llanerch, where it picked up a concurrency with US 1 Byp. and continued northeast along Township Line Road, City Avenue, East River Drive, Hunting Park Avenue, and Roosevelt Boulevard to Levick Street, where US 13 Byp. ended and US 13 continued along Levick Street. By 1950, the northern terminus of US 13 Byp. was cut back to Broad Street along Roosevelt Boulevard, being replaced by mainline US 13 north of there. The northern terminus was further scaled back to Hunting Park Avenue and East River Drive by 1960, with more of mainline US 13 replacing the bypass designation. Also by this time, the US 1 Byp. concurrency was removed, with mainline US 1 running concurrent with US 13 Byp. on Township Line Road, City Avenue, and East River Drive. US 13 Byp. was decommissioned in the 1960s.
