U.S. Route 13 Business (US 13 Bus.) is an 8.19-mile (13.18 km) business route of US 13 that runs through the heart of Wilmington in New Castle County, Delaware, where US 13 bypasses downtown Wilmington to the east, running near Interstate 495 (I-495) and the Delaware River. US 13 Bus. begins at US 13 at the southern border of Wilmington and heads north toward the downtown area, where it splits into a one-way pair. Past downtown, the business route heads through the northeastern part of the city on North Market Street before continuing through suburban Brandywine Hundred on Philadelphia Pike. US 13 Bus. reaches its northern terminus at US 13 in Claymont. US 13 Bus. is a four-lane road for much of its length.

The Philadelphia Pike was built in the 1820s and improved to a state highway by 1920. US 13 was designated to run through downtown Wilmington and along Philadelphia Pike in 1926. During the 1930s, US 13 was shifted from Market Street to a one-way pair on Market and French streets before both directions were moved onto French Street through downtown Wilmington. In the 1950s, the route was shifted to Walnut and French streets in the downtown area. The Walnut Street extension south of downtown, which included a new bridge over the Christina River, opened in 1957. US 13 Bus. was designated in 1970 when US 13 was routed to bypass Wilmington along the former US 13 Alternate (US 13 Alt.) The business route was moved to its current one-way pairing on Walnut and King street in the 1970s.

Route description

US 13 Bus. branches off of US 13 at the southern edge of Wilmington, just north of I-495. From here, the business route heads north on four-lane divided South Walnut Street. Immediately after beginning, the route has a southbound ramp to southbound I-495 and intersects Rogers Road. US 13 Bus. heads through commercial areas, becoming undivided as it comes to a bridge over Norfolk Southern's Shellpot Branch railroad line. The route splits into a one-way pair, with the northbound direction following South Walnut Street and the southbound direction following South Market Street, with three northbound lanes and four southbound lanes. The road passes businesses and a few homes and a high-rise apartment complex before the business route crosses the Christina River on the Walnut Street Bridge northbound and the South Market Street Bridge southbound, both of which are drawbridges.

US 13 Bus. heads into downtown Wilmington and crosses under Amtrak's Northeast Corridor railroad line at the Wilmington Station that serves Amtrak and SEPTA's Wilmington/Newark Line. Immediately after, the business route intersects the eastern terminus of DE 48, which follows Front Street eastbound and 2nd Street westbound. At this point, US 13 Bus. continues north to follow North Walnut Street northbound and North King Street southbound, with four northbound lanes and three southbound lanes. The road passes downtown businesses and intersects DE 9 (4th Street) near the New Castle County Court House. Continuing through the downtown, the business route carries three lanes in each direction and continues near high-rise buildings as it comes to a junction with the southern terminus of DE 52, which follows 11th Street eastbound and 12th Street westbound, near Rodney Square. At the north end of downtown, northbound US 13 Bus. turns west on 16th Street to rejoin the southbound direction.

From here, US 13 Bus. heads north of four-lane undivided North Market Street and crosses the Brandywine Creek. After the bridge, the road curves northeast and becomes a three-lane road with one northbound lane and two southbound lanes, passing urban residential and commercial development as it comes to an intersection with the southern terminus of DE 202 (Concord Avenue). The route becomes a two-lane road and passes more urban areas along with a couple cemeteries.

US 13 Bus. widens to four lanes again as it heads out of Wilmington and heads into suburban Brandywine Hundred, with the name of the road changing to Philadelphia Pike. Here, the business route intersects DE 3 near Bellefonte and forms a concurrency with that route. The two routes pass suburban homes and businesses, crossing Marsh Road before DE 3 splits from US 13 Bus. by heading to the northwest. US 13 Bus. continues northeast through residential neighborhoods with scattered businesses, heading through Holly Oak before it reaches Claymont. At Harvey Road, the road narrows to two travel lanes and a center turn lane until the business route intersects US 13 and reaches its northern terminus, with Philadelphia Pike continuing northeast as part of US 13.

The portion of the route between A Street and DE 9 (4th Street) in Wilmington is part of the Harriet Tubman Underground Railroad Byway, a Delaware Byway. US 13 Bus. has an annual average daily traffic count ranging from a high of 30,948 vehicles at A Street in Wilmington to a low of 8,384 vehicles at the DE 3 intersection near Bellefonte. US 13 Bus. is a part of the National Highway System between the southern terminus and DE 202 in Wilmington.

History

In 1813, the Wilmington and Philadelphia Turnpike Company was chartered to build a turnpike running from the Brandywine Bridge in Wilmington northeast to the Pennsylvania border, where the roadway would continue to Philadelphia. A 3.75-mile (6.04 km) long portion of the road near Wilmington was finished in 1816 with the remainder completed in 1823. With the Federal Aid Road Act of 1916, the Philadelphia Pike was to be improved by the state. The Philadelphia Pike was upgraded to a state highway by 1920.

In 1925, recommendations were made to improve the South Market Street Causeway over the Christina River in Wilmington, which included a new bridge over the river. Construction on the drawbridge began in May 1926. In 1927, the new drawbridge, the four-lane South Market Street Bridge, opened over the Christina River on South Market Street in Wilmington, replacing a previous drawbridge that was only two lanes wide.

With the creation of the U.S. Highway System in 1926, US 13 was routed to head through Wilmington along Market Street and to the northeast of Wilmington along Philadelphia Pike. In 1926, the Delaware State Highway Department suggested the Philadelphia Pike be widened. US 13 was widened along the Philadelphia Pike between Shellpot Park and Bellevue Quarry in 1927. In 1928, the widening of Philadelphia Pike was completed.

By 1932, US 13 was split into the one-way pair of French Street northbound and Market Street southbound in the downtown area. Both directions of the route was shifted to use French Street by 1936. On July 18, 1938, the grade crossing with the Reading Railroad and the Pennsylvania Railroad on South Market Street in Wilmington was eliminated with the opening of a bridge over the railroad tracks.

In 1952, a new bridge over the Christina River, the Walnut Street Bridge, was proposed to link Walnut Street in the downtown area with the Dupont Parkway section of US 13 south of the city. Under this plan, the Walnut Street Bridge would be used for northbound traffic while the South Market Street Bridge would be used for southbound traffic. By this time, US 13 was routed on a one-way pair in the downtown area, using Walnut Street northbound and French Street southbound. A year later, the Walnut Street Bridge project was under contract. Construction on the project began in 1955. Construction of the Walnut Street Extension, which included the drawbridge, approach roads, and a new bridge under the Pennsylvania Railroad, was completed in 1957. As a result, US 13 was split into the one-way pair of South Walnut Street northbound and South Market Street southbound between the south end of the city and downtown.

Plans were made to widen the Philadelphia Pike to a four-lane road between Bellevue Road and Claymont in 1954. The widening project was completed in 1956. US 13 Bus. was established in 1970, replacing the former alignment of US 13 through Wilmington that was shifted to bypass the city along the former US 13 Alt. By 1976, southbound US 13 Bus. was shifted to use King Street instead of French Street through downtown Wilmington.
