Delaware Route 1
Introduction


* + - * + - * + - * 
									**Delaware Route 1** (**DE 1**) is the longest numbered [state highway](/wiki/State_highway "State highway") in the U.S. state of [Delaware](/wiki/Delaware "Delaware"). The route runs  from the [Maryland](/wiki/Maryland "Maryland") state line in [Fenwick Island](/wiki/Fenwick_Island%2C_Delaware "Fenwick Island, Delaware"), [Sussex County](/wiki/Sussex_County%2C_Delaware "Sussex County, Delaware"), where the road continues south into that state as [Maryland Route 528](/wiki/Maryland_Route%C2%A0528 "Maryland Route 528") (MD 528\), north to an interchange with [Interstate 95](/wiki/Interstate_95_in_Delaware "Interstate 95 in Delaware") (I\-95\) in [Christiana](/wiki/Christiana%2C_Delaware "Christiana, Delaware"), [New Castle County](/wiki/New_Castle_County%2C_Delaware "New Castle County, Delaware"), where the roadway continues north as part of [DE 7](/wiki/Delaware_Route_7 "Delaware Route 7"). Between Fenwick Island and [Dover Air Force Base](/wiki/Dover_Air_Force_Base "Dover Air Force Base") in [Dover](/wiki/Dover%2C_Delaware "Dover, Delaware"), [Kent County](/wiki/Kent_County%2C_Delaware "Kent County, Delaware"), DE 1 is a multilane [divided highway](/wiki/Divided_highway "Divided highway") with at\-grade intersections and occasional interchanges. The route heads north through the [Delaware Beaches](/wiki/Delaware_Beaches "Delaware Beaches") resort area along the [Atlantic Ocean](/wiki/Atlantic_Ocean "Atlantic Ocean") before it runs northwest through rural areas, turning north at [Milford](/wiki/Milford%2C_Delaware "Milford, Delaware") to continue to Dover. Upon reaching Dover, DE 1 becomes the **Korean War Veterans Memorial Highway**, a [freeway](/wiki/Freeway "Freeway") that is partially [tolled](/wiki/Toll_road "Toll road"). Between Dover and [Tybouts Corner](/wiki/Tybouts_Corner%2C_Delaware "Tybouts Corner, Delaware"), DE 1 parallels [U.S. Route 13](/wiki/U.S._Route_13_in_Delaware "U.S. Route 13 in Delaware") (US 13\), crossing over and featuring interchanges with it multiple times. Past Tybouts Corner, the freeway heads north parallel to DE 7 to the northern terminus of DE 1 in Christiana. DE 1 serves as the main north\-south state highway in Delaware, connecting the Delaware Beaches with the Dover and [Wilmington](/wiki/Wilmington%2C_Delaware "Wilmington, Delaware") areas.

DE 1 was first designated in the 1970s from Fenwick Island north to [US 113](/wiki/U.S._Route_113 "U.S. Route 113") in Milford, replacing a portion of [DE 14](/wiki/Delaware_Route_14 "Delaware Route 14") south of Milford and following the newly\-constructed Milford Bypass. DE 14 between Fenwick Island and Milford had been built as a state highway in the 1920s and 1930s and was widened into a divided highway between the 1950s and 1970s. In the 1980s, a controlled\-access "Relief Route" of US 13 was proposed between Dover and the Wilmington area in order to relieve that route of beach traffic. This proposed highway was incorporated into DE 1 in 1988, with the route extended north [concurrent](/wiki/Concurrency_%28road%29 "Concurrency (road)") with US 113 between Milford and Dover to connect to the Relief Route. The DE 1 freeway between Dover Air Force Base and Christiana opened in multiple stages between 1991 and 2003, and at a cost of $900 million was the largest public works project in Delaware history. The concurrent US 113 designation between Milford and Dover Air Force Base was removed in 2004\. Upgrades continue to be made to DE 1 such as the construction and improvement of interchanges as well as widening portions of the road.
