Last updated August 15, 2024

The following is a list of numbered routes in Delaware, consisting of Interstate Highways, U.S. Routes, and state routes. The Delaware Department of Transportation is responsible for maintaining numbered roads in Delaware. State routes in Delaware use the circular highway shield. Delaware's numbering system mirrors that of U.S. Highways in that odd numbered highways travel north-south and even numbered routes go east-west. The numbers increase in value as one goes south and west respectively. There are some exceptions, however, mainly with routes from other states keeping their number as they enter Delaware, hence breaking the pattern.

History

The first numbered routes in Delaware came in 1925 with the designation of the U.S. Highway System, in which US 13, US 40, and US 113 were legislated to run through the state.^[1] In 1930 and again in 1932, the Delaware State Highway Department recommended giving numbers to state roads to supplement the existing U.S. Highway System.^[2]^[3] By 1936, Delaware began assigning numbers to state routes.^[4] In 1956, the Interstate Highway System was created, with under 40 miles of Interstate highway legislated in New Castle County.^[5]

U.S. Route 113 (US 113) is a U.S. Highway that is a spur of US 13 in the U.S. states of Maryland and Delaware. The route runs 74.75 miles (120.30 km) from US 13 in Pocomoke City, Maryland, north to Delaware Route 1 (DE 1) in Milford, Delaware. In conjunction with DE 1, US 113 is one of two major north–south highways on the Delmarva Peninsula that connect Dover with Pocomoke City and the Eastern Shore of Virginia. The U.S. Highway is the primary north–south highway in Worcester County, Maryland, where it connects Pocomoke City with Snow Hill and Berlin. US 113 is one of three major north–south highways in Sussex County, Delaware, where it connects Selbyville, Millsboro, and Georgetown with Milford. While US 113 does not pass through Ocean City or the Delaware Beaches, the U.S. Highway intersects several highways that serve the Atlantic seaboard resorts, including US 50, Maryland Route 90 (MD 90), US 9, DE 404, DE 16, and DE 1. US 113 is a four-lane divided highway for its whole length.

<span class="mw-page-title-main">Interstate 495 (Delaware)</span> Highway in Delaware

Interstate 495 (I-495) is an 11.47-mile-long (18.46 km) auxiliary Interstate Highway in the US state of Delaware. The highway, named the Vietnam Veterans Memorial Highway, serves as a six-lane bypass of I-95 around the city of Wilmington. I-495 begins at an interchange with I-95 and I-295 near Newport to the southwest of Wilmington. From here, the road heads east to the Port of Wilmington, where it turns northeast and crosses the Christina River as it heads to the east of downtown Wilmington. Upon reaching Edgemoor, I-495 runs between the Delaware River to the east and U.S. Route 13 (US 13) to the west, continuing to Claymont. In Claymont, I-495 turns north and merges into northbound I-95 at an interchange with Delaware Route 92 (DE 92) just south of the Pennsylvania state line.

Interstate 95 (I-95) is an Interstate Highway running along the East Coast of the United States from Miami, Florida, north to the Canadian border in Houlton, Maine. In the state of Delaware, the route runs for 23.43 miles (37.71 km) across the Wilmington area in northern New Castle County from the Maryland state line near Newark northeast to the Pennsylvania state line in Claymont. I-95 is the only primary Interstate Highway that enters Delaware, although it also has two auxiliary routes within the state. Between the Maryland state line and Newport, I-95 follows the Delaware Turnpike, a toll road with a mainline toll plaza near the state line. Near Newport, the Interstate has a large interchange with Delaware Route 141 (DE 141) and the southern termini of I-295 and I-495.

<span class="mw-page-title-main">Delaware State Route System</span> Overview of the State Route System of Delaware

The Delaware State Route System consists of roads in the U.S. state of Delaware that are maintained by the Delaware Department of Transportation (DelDOT). The system includes the portions of the Interstate Highway System and United States Numbered Highways system located in the state along with state routes and other roads maintained by DelDOT. All roads maintained by the state are assigned a maintenance road number that is only marked on little white markers at intersections and on auxiliary plates below warning signs approaching intersections. These numbers are only unique in a specific county; some roads can be designated with multiple road numbers, and numbers do not necessarily correspond to the signed Interstate, U.S., or state route numbers. DelDOT maintains a total of 5,386.14 miles (8,668.15 km) of roads, comprising 89 percent of the roads within the state. Some large bridges in the state are maintained by other agencies including the U.S. Army Corps of Engineers and the Delaware River and Bay Authority. Roads in the system include multilane freeways, multilane surface divided highways, and two-lane undivided roads serving urban, suburban, and rural areas. Some of the roads maintained by DelDOT are toll roads, in which motorists must pay to use.
