[[File:DE 1 NB from DE 299 overpass.jpeg|thumb|[[Delaware Route&nbsp;1]] (DE{{spaces}}1) is a partial [[toll road]] linking [[Fenwick Island, Delaware|Fenwick Island]] and [[Wilmington, Delaware|Wilmington]].]]
One major branch of the U.S. [[Interstate Highway System]], [[Interstate 95 in Delaware|Interstate{{spaces}}95]] (I-95), crosses Delaware southwest-to-northeast across New Castle County. Two [[Auxiliary Interstate Highway]] routes are also located in the state. [[Interstate 495 (Delaware)|Interstate 495 (I-495)]] is an eastern bypass of Wilmington. [[Interstate 295 (Delaware–Pennsylvania)|Interstate 295 (I-295)]] is a bypass of Philadelphia which begins south of Wilmington. In addition to Interstate highways, there are six [[U.S. Highway System|U.S. highways]] that serve Delaware: [[U.S. Route 9 in Delaware|U.S.{{spaces}}9]], [[U.S. Route 13 in Delaware|U.S.{{spaces}}13]], [[U.S. Route 40 in Delaware|U.S.{{spaces}}40]], [[U.S. Route 113 in Delaware|U.S.{{spaces}}113]], [[U.S. Route 202 in Delaware|U.S.{{spaces}}202]], and [[U.S. Route 301 in Delaware|U.S.{{spaces}}301]]. There are also several state highways that cross the state of Delaware; a few of them include [[Delaware Route 1|DE{{spaces}}1]], [[Delaware Route 9|DE{{spaces}}9]], and [[Delaware Route 404|DE{{spaces}}404]]. U.S.{{spaces}}13 and DE{{spaces}}1 are primary north–south highways connecting Wilmington and Pennsylvania with Maryland, with DE{{spaces}}1 serving as the main route between Wilmington and the [[Delaware beaches]]. DE{{spaces}}9 is a north–south highway connecting Dover and Wilmington via a scenic route along the [[Delaware Bay]]. U.S.{{spaces}}40 is a primary east–west route, connecting Maryland with New Jersey. DE{{spaces}}404 is another primary east–west highway connecting the [[Chesapeake Bay Bridge]] in Maryland with the Delaware beaches. The state also operates three toll highways, the Delaware Turnpike, which is I-95, between Maryland and New Castle; the Korean War Veterans Memorial Highway, which is DE{{spaces}}1, between Wilmington and Dover; and the U.S. 301 toll road between the Maryland border and DE{{spaces}}1 in New Castle County.

A bicycle route, [[Delaware Bicycle Route&nbsp;1]], spans the north–south length of the state from the Maryland border in [[Fenwick Island, Delaware|Fenwick Island]] to the Pennsylvania border north of [[Montchanin, Delaware|Montchanin]]. It is the first of several signed bike routes planned in Delaware.<ref>{{cite web|url=http://www.deldot.gov/information/projects/bike_and_ped/bike_facilities/pages/regional_routes.shtml|publisher=Delaware Department of Transportation|title=Projects: Delaware Bicycle Facility Master Plan|access-date=September 28, 2010|archive-url=https://web.archive.org/web/20100918130554/https://www.deldot.gov/information/projects/bike_and_ped/bike_facilities/pages/regional_routes.shtml|archive-date=September 18, 2010|url-status=dead}}</ref>

It has been noted that the [[tar and chip]] composition of secondary roads in Sussex County makes them more prone to [[Road surface#Surface deterioration|deterioration]] than are the [[Asphalt concrete|asphalt]] roadways in almost the rest of the state.<ref name=nj20110417>{{cite news |location=Wilmington, Delaware |title=Anything Once: On the road, taking plenty of pot shots |author=Justin Williams |url=http://www.delawareonline.com/article/20110417/NEWS02/304170008/-1/NLETTER01/On-the-road--taking-plenty-of-pot-shots |newspaper=News Journal |date=April 17, 2011 |at=DelawareOnline |access-date=April 17, 2011 }}{{dead link|date=May 2016|bot=medic}}{{cbignore|bot=medic}}</ref> Among these roads, Sussex (county road) 236 is among the most problematic.<ref name=nj20110417/>
