The Guide to U.S. Highway 13 in Delaware

Known as the Dupont Highway or Parkway from Wilmington to the Maryland state line, U.S. 13 composes the longest signed highway within the state of Delaware. U.S. 13 enters the state north of Salisbury, Maryland at the town of Delmar. From there the US highway continues northward to Seaford, Laurel, Greenwood, Harrington, Camden, Dover, Smyrna, Odessa, Wilmington, and Claymont. The US highway crosses the Pennsylvania state line via Philadelphia Pike into Marcus Hook, Pennsylvania. U.S. 13 varies between four to six lanes throughout the entire state.

The Dupont Highway

The origins of the Dupont Highway predate the U.S. Highway system. T. Coleman du Pont, an engineer of the Delaware famous du Pont family, envisioned a paved route traveling statewide from south to north. Coleman du Pont proposed the project to the citizens of Delaware in 1908. His concept entailed the creation of separate north and southbound lanes, trolley lines, and pathways for horse-drawn vehicles. By 1924 a two-lane version of the highway opened to traffic between the southern agricultural areas and the urbanized center of Wilmington. The road was a huge success and by 1933 the State Highway Department expanded the highway, making it the world's first divided highway.1

U.S. 13 From north to south

U.S. 13 enters the state of Delaware from the industrial city of Marcus Hook, Pennsylvania as Philadelphia Pike. The four lane undivided highway intersects the east end of Delaware 92 (Naamans Road) near the CitiSteel plant in Claymont. South of there is a partial cloverleaf interchange with Interstate 495. The community of Claymont features a hodgepodge of shopping centers, residential subdivisions, and industrial facilities. Philadelphia Pike is the main arterial through the area.

U.S. 13 Northbound at Alcott Avenue in Claymont

U.S. 13 southbound departs the Philadelphia Pike (former Wilmington Post Road) for Governor Printz Boulevard one half mile south of the Interstate 495 junction in Claymont. Governor Printz Boulevard straddles the southbound side of Interstate 495 between Claymont and the Bellefonte Area with four lanes and a grassy or concrete median. Philadelphia Pike continues southward into Wilmington as U.S. 13 Business. Originally Governor Printz Boulevard carried U.S. 13 Alternate shields as U.S. 13 remained on the Philadelphia Pike through the city. The switch was made in the 1970s.

At Edgemoor U.S. 13 (Governor Printz Boulevard) intersects Delaware 3 (Edgemoor) adjacent to the 1989-constructed Exit 4 interchange of Interstate 495. The junction allows motorists from the Bellefonte and East Lawn neighborhood of Wilmington access to the six-lane Wilmington Bypass. A large industrial complex owned by Dupont resides nearby in the Edgemoor Industrial Park. U.S. 13 continues south of Delaware 3 by the old Merchants Square Shopping Center. What was bustling in the 1950s is almost complete abandoned in the 2000s. The new interchange did not help rejuvenate the shopping center or the local economy otherwise.

Southwest of Edgemoor is the Wilmington city line and U.S. 13 transition from Governor Printz Boulevard into Northeast Boulevard. Northeast Boulevard carries five lanes between the city line and the Brandywine Creek crossing at Twelfth Street. The East Lawn section of the city is generally regarded as ghetto and is in a state of economic decline. Upon crossing the Brandywine Creek, U.S. 13 enters the East Side section of the city. The recently reconstructed Kirkwood Park features ornamental lighting and greenery for motorists entering the heart of the city. There U.S. 13 splits between a the one-way street couplet of Spruce Street (southbound) and Church Street (northbound). The ten block alignment of these streets pass through impoverished neighborhoods.

At Fourth Street (Delaware 9), U.S. 13 turns eastward to cross the Christina River via a drawbridge. The two highways overlap across the bridge and into the South Bridge section of the city. Three blocks south of the Christina Avenue intersection (Delaware 9A), U.S. 13 & Delaware 9 split between Heald Street southbound and New Castle Avenue northbound. The environs of South Bridge are dilapidated and ghetto like and U.S. 13 & Delaware 9 is not a recommended through route. The one-way couplet of U.S. 13 & Delaware 9 ends in six blocks for southbound motorists and five blocks for northbound motorists. A connector ramp carries Delaware 9 southbound motorists underneath the Heald Street bridge over the Norfolk Southern Railroad line to New Castle Avenue. U.S. 13 northbound utilizes D Street for one block between the same bridge and New Castle Avenue (Delaware 9).

U.S. 13 & Delaware 9 - South Bridge Wilmington

U.S. 13 & Delaware 9 southbound on Heald Street in the South Bridge neighborhood of Wilmington. The overlapped route splits between the one-way couplet of Heald Street (southbound) and New Castle Avenue (northbound) between Lobdell Street (pictured here) and the Norfolk Southern Railroad bridge four blocks to the south. Photo taken April 10, 2004.

One half mile south of the split with Delaware 9, U.S. 13 (Heald Street) merges with U.S. 13 Business (Market Street) at the confluence of Rogers Road and Interstate 495 Exit 1. The intersection forms the north end of the Dupont Parkway alignment that carries U.S. 13 southward to the Maryland state line. Rogers Road stems southeast from the intersection connecting U.S. 13 with Delaware 9 (New Castle Avenue). The junction with Interstate 495 features ramps to both Interstate 495 north and southbound from U.S. 13 southbound and to Interstate 495 northbound from U.S. 13 northbound. A new ramp was built in 2000 to give southbound motorists the option to access Interstate 495 northbound.

U.S. 13 widens to six lanes through the Minquadale community south of Interstate 495. Several traffic lights dot the stretch of U.S. 13 between Interstate 495 and the SR 1 Turnpike at Tybout's Corner. U.S. 40 merges onto the Dupont Parkway from Interstate 295 just south of Minquadale. The junction between Interstate 295 and Dupont Parkway saw reconstruction between 2001 and 2003. The southbound ramp to Interstate 295 was eliminated and replaced with a left-hand turn that utilizes the U.S. 13 northbound ramp to the freeway. Ramps from Interstate 295 south & U.S. 40 west to U.S. 13 were also redesigned in the process. The interchange represents the north end of the four-mile U.S. 13 & 40 overlap. The junction also represents the historic northern end of U.S. 301 and southern end of U.S. 202.

The U.S. 13 & 40 overlap of the Dupont Highway between Interstate 295 (Farnhurst) and State Road features eight lanes of travel and heavy traffic. The corridor is home to New Castle County Airport and the Delaware Farmer's Market and outdoor Flea Market among other commercial establishments. The runway lights of the airport itself extend over the busy Hare's Corner intersection of U.S. 13 & 40 with Delaware 273 (Christiana and Frenchtown Roads). Set just north of the airport is a three-quarter cloverleaf interchange with U.S. 202 & Delaware 141 (Basin Road). The junction features the southern terminus of U.S. 202. Generally Delawareans do not acknowledge U.S. 40 on the stretch between State Road and Farnhurst. Additionally reassurance shields almost always omit U.S. 40 from the alignment.

U.S. 13 & 40 southbound split at State Road

The U.S. 13 southbound split from U.S. 40 westbound at State Road. U.S. 13 continues with two lanes on the Dupont Highway to Tybout's Corner. U.S. 40 travels the four-lane Pulaski Highway to the community of Bear. U.S. 301 no longer exists here but DelDOT has yet to alter the signs to reflect that. Photo taken May 1, 2004.

At State Road, the name of the community where U.S. 13 & 40 split, is the beginning of the Delaware to Baltimore Pulaski Highway. The Pulaski Highway carries U.S. 40 westward from the Dupont Highway to Bear and Glasgow. Bear and Glasgow represent some of the fastest growing areas in the state as suburban sprawl continues the spread of population southward. Southward U.S. 13 also sees a significant amount of development on the ride between U.S. 40 and Tybout's Corner.

Opened in 1991, the first section of the SR 1 Turnpike travels from U.S. 13 at Tybout's Corner northward to U.S. 40 at Bear. The four-lane freeway sees a wide trumpet interchange at U.S. 13 (Dupont Highway) adjacent to the northern terminus of Delaware 71 (Red Lion Road) and the local highway Bear Tybouts Road. From here southward U.S. 13 & Delaware 1 share three miles of pavement.

The construction of the SR 1 Turnpike between 1992 and 1995 overtook much of the Dupont Highway routing of U.S. 13 between Tybout's Corner and Wrangle Hill. In fact the original roadway was built upon between Delaware 71 and Red Lion Creek. Segments of the original Dupont Highway are visible south of the creek to the Delaware 7 (Bear Corbitt Road) undercrossing. The northbound carriageway of the former route sits abandoned. The southbound carriageway acts as a two-lane frontage road for a few homes and businesses.

At Delaware 7, U.S. 13 & Delaware 1 travel west of the original Dupont Highway. Delaware 7 saw extension southward from its previous terminus at U.S. 13 onto the Dupont Highway to Wrangle Hill and junction Delaware 72. U.S. 13 remains on the freeway southward to the Exit 152 diamond interchange with Delaware 72 (Wrangle Hill Road). There the US highway departs the SR 1 Turnpike for Delaware 72 east and the Dupont Highway. The formerly congested intersection of U.S. 13 & Delaware 72 at Wrangle Hill is vastly quiet now that the SR 1 Turnpike carries all through traffic.

U.S. 13 remains on the Dupont Highway indefinitely from Wrangle Hill southward to the Maryland state line. The four lane divided highway features a grassy median between Delaware 7 & 72 and the Saint Georges Bridge. Cut in half by the creation of the Chesapeake and Delaware Canal, the village of St. Georges resides on the U.S. 13 corridor both north and south of the bridge by the same name. The steel arch bridge that carries U.S. 13 over the canal opened in the 1950s. For many years in the 1980s and early 1990s, a weight restriction was levied on the span due to structure flaws with the concrete deck. An official detour and the creation of U.S. 301 Truck mandated that all heavy truck traffic use the Summit Bridge crossing to the west. When the SR 1 Turnpike bridge opened to traffic on December 23, 1995, it was thought that the St. Georges Bridge would be decommissioned and dismantled. However a bitter battle ensued between the state, the Army Corps of Engineers, and St. Georges area residents about the future of the bridge. After a temporary closure in 1997 and a bridge redecking in 2001, the St. Georges Bridge remains in operation to this day.

U.S. 13 southbound approaching the St. Georges Bridge

U.S. 13 (Dupont Highway) southbound approaching the St. Georges Bridge over the Chesapeake and Delaware Canal. Not only did the steel arch bridge receive a new deck in 2001 and 2002, but the superstructure of the span received a new paint job. Otherwise the four-lane bridge carries light traffic between the two St. Georges. Photo taken April 17, 2004.

The SR 1 Turnpike crosses over U.S. 13 midway between South St. Georges and the community of Boyd's Corner. At Boyd's Corner is the southern terminus of Delaware 896 (Boyds Corner Road) and the Exit 142 diamond interchange of the SR 1 Turnpike. At one time U.S. 301 departed U.S. 13 for Boyds Corner Road from the Dupont Highway. Signs still remain reflecting U.S. 301 on U.S. 13 southbound at the signalized intersection.

U.S. 13, free from beach through traffic for the most part, travels southward from Boyd's Corner into the quaint town of Odessa. What once was a traffic nightmare due to long red light cycles at the Delaware 299 (Main Street) intersection and slower speed limits through town is now bypassed by the SR 1 Turnpike to the west. The Odessa section of the freeway opened to traffic November of 1999. For a brief while U.S. 13 utilized the new highway as portions of the old highway were reconstructed to accommodate the new tollway. Now U.S. 13 remains east of the turnpike from Odessa southward to Smyrna.

The Dupont Highway becomes rural in nature between Odessa and Smyrna. Delaware 71 (Summit Bridge Road) ends at the highway near the community of Townsend. The north-south route links U.S. 13 with the growing city of Middletown to the northwest. Otherwise the nearby SR 1 Turnpike carries the bulk of through traffic to the east. A new interchange however is planned for Delaware 71 to the turnpike for Townsend and Middletown interests.

U.S. 13 travels underneath the Exit 119 interchange of the SR 1 Turnpike at north Smyrna. Between 1993 and 2003, U.S. 13 used to loop around the temporary north end of the SR 1 Turnpike Dover-Smyrna bypass segment. A Delaware Welcome Center and rest area complex resides along the southeastern quadrant of the interchange serving both U.S. 13 and Delaware 1 based motorists. Further south U.S. 13 travels the main strip through Smyrna with a variety of restaurants and other services for SR 1 Turnpike based motorists. A second interchange exits with the turnpike south of town at Exit 114. In town Delaware 6 & 300 connect U.S. 13 with western reaches of Kent County and the state of Maryland. Delaware 6 shares a short overlap with the Dupont Highway between Glenwood Avenue and Commerce Street.

The SR 1 Turnpike remains east of the U.S. 13 corridor from Smyrna southward to the capital city of Dover. The December 21, 1993 opening of the turnpike around Smyrna and Dover decreased traffic counts on the Dupont Highway dramatically between the two cities. U.S. 13 otherwise continues with four lanes and a grassy median with a scattering of homes and commercial strip malls on the stretch. Near the city of Dover is the Exit 104 (Scarborough Road) interchange of the SR 1 Turnpike. For motorists wishing to access U.S. 13 in the city of Dover from the turnpike, the trumpet interchange is the last opportunity from the north. The access road between U.S. 13 and the turnpike saw extension in the 1990s as Scarborough Road from the Dupont Highway southwestward to Delaware 15 (McKee Road).

Dover Map - AARoads

U.S. 13's path through the capitol city of Dover. U.S. 13 Alternate travels through downtown while U.S. 13 constitutes the main commercial corridor. U.S. 113 used to split with U.S. 13 at Bay Road, but now ends in Milfred. Bay Road remains an important arterial, connecting U.S. 13 with the SR 1 Turnpike and Dover A.F.B.

In Dover itself U.S. 13 widens to three lanes and is heavily developed. Stop and go traffic dominates the flow of traffic through the capital city. Adjacent to Silver Lake is the U.S. 13 Alternate southbound beginning via State Street. The Alternate route carries U.S. 13 motorists through the downtown and capital district area of the city. U.S. 13 meanwhile stays east of the old town and intersects Delaware 8 (Division Street) and the historic northern terminus of U.S. 113 (Bay Road) & U.S. 113 Alternate. Until 1993, Dover was plagued with through traffic destined for the Delaware and Maryland coastal towns by way of U.S. 113 (Bay Road) and Delaware 1. In February of 2004 DelDOT won approval from AASHTO to truncate U.S. 113 southward from Dover to the merge with Delaware 1 north of Milford. So U.S. 113 through Dover is now simply known as Bay Road, a four lane surface arterial between the Dupont Highway and Dover Air Force Base.

U.S. 13 southbound at Delaware 8 (Division Street) in Dover

The Dupont Highway expands to six overall lanes through the capital city of Dover. Numerous traffic lights and heavy commercial development represent the landscape of U.S. 13 through the city. Pictured here is the intersection of U.S. 13 southbound with Delaware 8 (Division Street). Photo taken April 13, 2004.

U.S. 13 reduces to four lanes southwest of the Bay Road intersection but retains a commercialized frontage and busy feel. A new freeway opened to traffic around New Year's Day 2001 between the SR 1 Turnpike and U.S. 13 south of town. Designated the Puncheon Run Connector, the four-lane freeway gives SR 1 Turnpike motorists uninterrupted access to U.S. 13 and vice versa. The connection allows through traffic motorists destined for Salisbury, Maryland, Norfolk, Virginia, and other points downstate access to the turnpike to bypass the city.

At Camden a second U.S. 13 Alternate departs along Main Street through the heart of town. The former through route between Dover and Camden continues southward via Upper King Road through Woodside before returning to U.S. 13. The Dupont Highway stays to the east of these two towns for the most part with four lanes and a grassy median. Delaware 10 intersects U.S. 13 at Camden by way of Camden Wyoming Avenue and Lebanon Road. The east-west route provides the main route between U.S. 13 and Dover Air Force Base.

Northbound U.S. 13 approaching the Puncheon Run Connector of the SR 1 Turnpike. The limited access highway connects U.S. 13 with Bay Road (former U.S. 113) and Delaware 1 near Dover A.F.B. It provides a non-stop link between U.S. 13 south of Dover to the SR 1 Turnpike and points North. Photo taken by JP Nasiatka (09/01).

Small towns and farmland compose the landscape of U.S. 13 in southern Delaware. U.S. 13 intersects Delaware 12 (Midstate Road) at Felton and Delaware 14 (Milford Harrington Highway) at Harrington in southern Kent County. In Sussex county U.S. 13 passes by Greenwood (junction Delaware 16 & 36) and Bridgeville (home to another Business U.S. 13). At Bridgeville U.S. 13 joins Delaware 404 for a 2.5-mile overlap east of town. Delaware 404 provides the preferred beach route for the Baltimore and Washington Metropolitan areas by way of U.S. 50, the Chesapeake Bay Bridge, and Maryland 404. A short distance south of the U.S. 13 Business & Delaware 404 Business merge with U.S. 13 is junction Delaware 18 (Bowdens Garage Road). Delaware 18 links U.S. 13 with Federalsburg, Maryland by way of Maryland 318 and the county seat of Georgetown by way of Delaware 404. Five miles south of Delaware 18 is the city of Seaford. Seaford, known as the hometown for Delaware Major League Baseball player Delino Deshields, features a one-mile overlap with Delaware 20 across the Nanticoke River. Delaware 20 (Concord Road) travels eastward from Blades to Millsboro (junction U.S. 113) and Fenwick Island along the coast.

Five miles south of Blades is where U.S. 13 intersects the southern terminus of U.S. 9 (County Seat Highway). In the 1970s U.S. 9 extended into the state of Delaware by way of the Cape May-Lewes Ferry to Georgetown and Laurel. What was once Delaware 28 is now U.S. 9 between Laurel (junction U.S. 13) and Georgetown (junction U.S. 113). The Dupont Highway again stays east of town on a four-lane alignment as the two-lane Seaford Road travels through Laurel. Just south of Records Point at Laurel is the intersection of U.S. 13 with Delaware 24 (Laurel Road). The state highway arcs between the Maryland state line and Laurel, Millsboro, and Midway (junction Delaware 1). U.S. 13 departs the state at the Maryland and Delaware town of Delmar. The US highway intersects Delaware & Maryland 54 (Maryland Delaware Line Road) at the state line. The multi-state route begins at Mardela Springs, Maryland and ends at Fenwick Island.

U.S. 13 Highway Guides

ALTERNATE

Canterbury to Camden

The first U.S. 13 Alternate begins at the community of Canterbury at the Dupont Highway junction with Delaware 15 (Canterbury Road and Upper King Road). From there U.S. 13 Alternate & Delaware 15 travel Upper King Road into the town of Woodside. There Delaware 15 turns left onto Walnut Shade Road as U.S. 13 Alternate continues north along Upper King Road. At the Dover suburb of Camden U.S. 13 Alternate becomes Main Street. The two lane highway remains west of U.S. 13 and intersects Delaware 10 (Camden Wyoming Avenue) between the Dupont Highway and town of Wyoming. The final half mile of U.S. 13 Alternate is designated Old Camden Road. Old Camden Road ends at U.S. 13 0.4 miles south of the Governors Avenue U.S. 13 Alternate in Dover.

Dover (Governors Avenue & State Street)

A second U.S. 13 Alternate exists in the capital city of Dover. The Dover version of U.S. 13 Alternate follows Governors Avenue west of the Dupont Highway between Webbs Lane and downtown. Where State Street intersects U.S. 13, U.S. 13 Alternate splits into one-way street couplets (Governors Avenue southbound and State Street northbound). The state capital complex resides along the State Street routing of U.S. 13 Alternate northbound.

At Silver Lake Governors Avenue merges with State Street. 0.6 miles north of Walker Road is the northern terminus of U.S. 13 Alternate (State Street) at U.S. 13 (Dupont Highway). The US highway crosses Silver Lake between Walker Road and the north endpoint.

South Wilmington to Claymont Decommissioned

U.S. 13 Alternate followed the current U.S. 13 mainline between south Wilmington and Claymont via Heald Street, New Castle Avenue, 4th Street, Church & Spruce Streets, Northeast Boulevard, and Governor Printz Boulevard. At the time U.S. 13 traveled through downtown on what is now U.S. 13 Business. U.S. 13 and U.S. 13 Alternate switched alignments in the late 1970s near the time Interstate 495 opened to traffic.

BUSINESS

Bridgeville

U.S. 13 Business loops westward from the Dupont Highway into downtown Bridgeville via Main Street. The Sussex County town resides at the junction of U.S. 13 & Delaware 404 (Seashore Highway). In 1998, Delaware 404 relocated to a new alignment north of town and a 2.5-mile overlap with U.S. 13. The original Delaware 404 mainline through Bridgeville became Delaware 404 Business. Delaware 404 Business travels Market Street eastward into downtown where it intersects U.S. 13 Business (Main Street). There the two highways join together for a 1.5-mile overlap to south of town. U.S. 13 Business ends with Delaware 404 Business at the U.S. 13 intersection with the Seashore Highway (Delaware 404). Signs for U.S. 13 Business on the Dupont Highway at that point refer to the business loop as U.S. 13 Alternate.

U.S. 13 Business Mileage: 2.46

U.S. 13 Business - Bridgeville
U.S. 13 Business and Delaware 404 Business merge at the intersection of Main and Market Streets in downtown Bridgeville (pop. 1,436). The tandem travels southward through residential areas along Main Street for 1.5 miles. Note the assumption that Delaware 404 is Delaware 404 Business made by the posting of the reassurance shields. Delaware 404 saw relocation outside of Bridgeville by 1999. Photo taken 04/13/04.
Departing Bridgeville on U.S. 13 Business south & Delaware 404 Business east (Seashore Highway). Posted here is a junction shield for U.S. 13 for the upcoming intersection with the Dupont Highway. Both U.S. 13 Business and Delaware 404 Business draw to a close here. Photo taken 04/13/04.
Motorists bound for Fenwick Island and other southern shore points are advised to turn southward on U.S. 13 for either Delaware 20 or Delaware 24 east instead of remaining on Delaware 404. Motorists continuing through the intersection return onto Delaware 404 eastbound as the state highway leaves the overlap with U.S. 13. Photo taken 04/13/04.
No end signs are posted for either U.S. 13 Business or Delaware 404 Business. Several travel amenities are accessible at the Seashore Highway and U.S. 13 intersection otherwise. For motorists turning southward, U.S. 13 intersects Delaware 18 in 1.7 miles, Delaware 20 in five miles, and U.S. 9 in 11 miles. Delaware 404 itself merges with Delaware 18 (Bowdens Garage Road) 1.7 miles to the east. Photo taken 04/13/04.

BUSINESS

Wilmington

U.S. 13 Business constitutes the original routing of U.S. 13 through Wilmington. It was commissioned at the same time Alternate U.S. 13 was decommissioned. Beginning from the south at I-495 where U.S. 13 splits to the east to Edgemoor, Business U.S. 13 follows South Market Street crossing the Christiana River on a drawbridge. From here it splits near DE 48 by the Amtrak station at the developing river front park district. Northbound follows Walnut St. while southbound follows King St. Business U.S. 13 cuts right through the heart of the business district of Wilmington. At the Brandywine Creek north and southbound merge back together and follow Market St. through northeastern Wilmington. North of the city limits Business U.S. 13 widens to 4 lanes and is known as Philadelphia Pike en route to the Northern terminus with U.S. 13, just south of I-495.

U.S. 13 Bypass was temporary designation applied to Delaware 1 between Exit 152 and South St. Georges over the Chesapeake and Canal Bridge. The route remained in place from 1995 to 1998 to get U.S. 13 motorists used to the SR 1 Turnpike bridge west of St. Georges. At the time it was thought that the St. Georges Bridge would be closed and for a short while in 1997, it was. U.S. 13 Bypass was decommissioned and U.S. 13 remains on the Dupont Highway and St. Georges Bridge to this day.
