Routes in Delaware

DE 896 DE 1A

Delaware Route 1 (DE 1) is a 103.02-mile-long (165.79 km), four- to six-lane highway going from the MarylandDelaware line on the eastern Atlantic shoreline to the Delaware Turnpike (Interstate 95) outside of Wilmington.

The highway, which came into existence in the late 1970s, was originally a two-lane road and signed as part of DE 14, but DE 14 was truncated to Milford when the Delaware Department of Transportation (DelDOT) adopted a U.S. Highway-style system for its state routes. From the early 1970s to 1995, the highway ended at is what is now U.S. Route 113 (US 113), but in the mid-1970s, the DOT studied a "Dover Extension" of the Delaware Turnpike, which evolved into today's Korean War Veterans Memorial Highway.

Route description[edit]

Delaware–Maryland state line to Lewes[edit]

DE 1 southbound in Rehoboth Beach, approaching DE 1A

DE 1 starts at the Maryland–Delaware state line a block south of the intersection with DE 54 in Fenwick Island, Delaware, as an extension of Maryland Route 528 (MD 528) at the border with Ocean City, Maryland. The road, mostly four lanes with six-lane sections in the resort areas, follows the Atlantic shore line as Coastal Highway, containing nearly 50 miles of traffic signals and crossroads. The road travels through Fenwick Island State Park and South Bethany before it comes to Bethany Beach, where it intersects DE 26. North of Bethany Beach, the route heads into Delaware Seashore State Park. Upon entering the park, DE 1 crosses over the Indian River Inlet, a connection between the Rehoboth and Indian River Bays and the Atlantic Ocean itself, on the Indian River Inlet Bridge.

Past the inlet, DE 1 continues north through the state park, passing lookout towers used by the U.S. Army's Coastal Artillery forces during World War II, until the road enters Dewey Beach. It is here in Dewey Beach that DE 1A branches off and heads towards Rehoboth Beach, while DE 1 curves towards the west and intersects DE 1B before it crosses over the Lewes and Rehoboth Canal on a high-level, twin span crossing (completed in the mid-1980s) before reabsorbing DE 1A. Between the northern junction of DE 1A and Lewes, DE 1, now a six-lane road, passes through commercial areas which includes the Tanger Outlets Rehoboth Beach outlet mall complex. In Midway, the route intersects the eastern terminus of DE 24 and DE 1D branches off as a bypass route to the west. Near Lewes, DE 1 intersects US 9, which allows direct access to the Garden State Parkway and the New Jersey shore via the Cape May-Lewes Ferry. US 9 and DE 1 become concurrent at this point and continue northwest to the Five Points intersection. Here, US 9 and DE 404 head west, DE 23 and DE 1D head south, and US 9 Business heads east into Lewes. DE 404 allows access to Central Maryland via the Chesapeake Bay Bridge on US 50.

Lewes to Dover Air Force Base[edit]

Southbound DE 1 between Milford and Milton

Past the US 9 / DE 404 intersection, and crossing over the Delaware Coast Line Railway's Lewes Branch, DE 1 starts a 20-mile (32.19 km) run through a rural stretch of Sussex County, going past the Prime Hook National Wildlife Refuge near Milton, while at the same time, intersecting both DE 16 and DE 5 in the process. After an interchange between DE 1 and DE 30, DE 1 Business (DE 1 Bus.), a former two-lane stretch of DE 1, breaks off, and the roadway continues east of Milford, Delaware on the Milford Bypass, where it meets DE 36 at a diamond interchange. Unlike a true bypass, which has grade-separated interchanges, the Milford Bypass has both grade-separated interchanges and at-grade intersections, of which one of them intersects with DE 14, an east–west state highway that originally went from Fenwick Island to Harrington, but was truncated to Milford in 1978 when DelDOT renumbered its state highway system to be consistent with the numbering used for the U.S. Highway System.

Southbound DE 1 at Frederica Road south of Frederica

North of DE 14, the Milford Bypass portion of DE 1 ends with the junction of DE 1 with US 113. Prior to 2004, both DE 1 and US 113 continued north together to Dover Air Force Base on a two-route concurrency; after numerous petitions by DelDOT, the American Association of State Highway and Transportation Officials, which governs the regulation of designating Interstate and U.S. Highways, allowed DelDOT to truncate US 113 at this interchange. Prior to 1992, the DE 1/US 113 interchange served as the northern terminus for DE 1, but with the construction of the Korean War Veterans Memorial Highway, DelDOT extended the DE 1 designation north of this interchange to prevent a "gap" between the Fenwick Island – Milford section and the toll highway.

Past US 113, the highway continues north towards Dover, passing Frederica (on a high-speed bypass), where it has an interchange with DE 12. After this, the route passes through Little Heaven before crossing over the St. Jones River on a high-level crossing that was built in the mid-1980s as part of a US 113 widening project between Dover and Milford. Past the St. Jones River crossing, DE 1 meets DE 9 at a grade-separated interchange. DE 9 is a two-lane rural road that, prior to the completion of the Korean War Veterans Memorial Highway, served as a "bypass" of the usually congested US 13.

Dover Air Force Base to Wilmington[edit]

Southbound DE 1 between Smyrna and Dover

After passing DE 9, DE 1 becomes the 51-mile (82.08 km) tolled "Korean War Veterans Memorial Highway" (originally called the "Relief Route", the current name being given after the dedication of the Korean War Veterans Memorial in Washington, D.C., in 1995). After passing another exit, for access to both the base itself and its housing complex, DE 1 then splits off from the former US 113 highway at DE 10 and then follows a high-speed four-lane highway east of Dover. This section opened in 1992 and built (like all of its sections) to Interstate Highway standards (containing no traffic signals, crossroads, or businesses), was the first highway on the East Coast to be marked with metric measurements. The metric measurements are due to anticipation during the administration of then-President Bill Clinton that the standard U.S. measurement would be dropped and the metric system be adopted. Although the route is now marked with standard milepost markers, the experimental signs with metric measurements are still in place today—the exit numbers on the highway are still in metric as opposed to the standard U.S. milepost exit system used on the majority of Interstate Highways in the U.S.

After passing through the toll plaza in Dover, which has, since 2004, both cash and high-speed E-ZPass lanes, DE 1 meets US 13 for the first time, north of both the toll plaza and Dover International Speedway. Between Dover and Wilmington, DE 1 will pass over US 13 a total of five times, with direct access to the highway a total of three times. Other connections between the routes are via Delaware State Highway routes or with US 40.

Route 1 (Korean War Veterans Memorial Highway) approaching the Senator William V. Roth, Jr. Bridge that crosses Chesapeake and Delaware Canal near St. Georges

North of the first DE 1/US 13 interchange, the highway roughly parallels US 13 through the northern fringes of Dover, interchanges with US 13 in the southern part of Smyrna, and enters New Castle County to the east of Smyrna. At the third interchange with US 13, which served as a temporary northern terminus between 1992 and 2003, the highway crosses over US 13 and then travels for the next 8 miles (13 km) past the small rural community of Townsend, before crossing over the Appoquinimink River and meeting DE 299 on the way to Odessa and Middletown. Past DE 299, DE 1 then crosses over US 13 and the Drawyer Creek, interchanging with DE 896 in Boyds Corner.

DE 1/DE 7 southbound at I-95 northbound ramp in Christiana

After DE 896, the road then crosses over US 13 before reaching the Biddles Corner Toll Plaza, the first toll plaza on the East Coast to have both high-speed E-ZPass and cash lanes, and, with some design changes, has served as a model for dual-speed mainline toll barriers on both the Pennsylvania Turnpike, New Jersey Turnpike, as well as the Garden State Parkway and Atlantic City Expressway. Passing through the toll barrier, the highway then crosses the Chesapeake and Delaware Canal on the Chesapeake and Delaware Canal Bridge, a cable-stayed bridge which was originally opened in 1995 as a replacement for the aging St. Georges Bridge and now serving as an integral part of the DE 1/US 13 corridor between Dover and Wilmington. DE 1 widens to six lanes after the toll plaza, and passes through the interchange with DE 72, where US 13 joins the DE 1 freeway. The two highways separate shortly after in Tybouts Corner.

North of the DE 1/US 13 split, the highway, now back to four lanes, starts a short trip north towards I-95 (Delaware Turnpike), passing US 40 and DE 273 before merging with DE 7 near the Christiana Mall in Christiana. After merging with DE 7, the route continues north until it meets I-95 at an interchange (with flyover ramps for I-95 north), and then immediately after interchanges with DE 58 near Churchmans Crossing. After the DE 58 interchange, the DE 1 designation is dropped, and the now at-grade highway becomes just DE 7.


The Biddles Corner mainline toll plaza, with high speed E-ZPass lanes

As of August 1, 2014, DelDOT charges a total of $2 on weekdays ($6 on weekends) for the entire 51-mile (82 km) length of highway, with mainline toll plazas at Dover and Biddles Corner which each charge $1 on weekdays ($3 on weekends). Weekend tolls are in effect from 7:00 pm Friday until 11:00 pm Sunday. In addition, DelDOT charges a $0.50 toll at exit 104 for US 13 in North Dover (southbound off, northbound on), exit 142 for DE 896 in Boyds Corner (northbound off, southbound on) and a $0.25 toll at exit 114 for US 13 in South Smyrna (southbound off, northbound on). Tolls may be paid with cash or E-ZPass. A discount is available for motorists with E-ZPass exiting northbound and entering southbound at exits 104 and 114 north of the Dover toll plaza as well as entering northbound and exiting southbound at exit 142 south of the Biddles Corner toll plaza. This discount is $0.50 at exits 104 and 142 and $0.25 at exit 114.[2] There is also a frequent user plan in which E-ZPass users who make at least 30 trips in 30 days receive a 50% discount on tolls.[3]

Tolls at the Dover and Biddles Corner mainline toll plazas were originally $1 the whole week. On October 1, 2007, tolls on weekends were increased to $2 in order to fund statewide transportation projects. Commercial vehicle tolls also increased by $1 on weekdays and $2 on weekends at this time.[4] On August 1, 2014, the weekend tolls at Dover and Biddles Corner increased to $3 in order to again provide funding to transportation projects across the state.[5]


There were talks of extending the highway portion of the road down into the Delmarva Peninsula. It would go down into Maryland and Virginia. Then it would cross the 17 mile Chesapeake Bay Bridge-Tunnel and into Norfolk, Virginia mainly following U.S. 13. Then it would have gone into Raleigh, North Carolina and end there. It would bring relief towards exiting the Hurricane Zone but there is no main highway connecting, and the Tunnels in the CBBT are two lanes. It would cost somewhere between $500 million towards $1 billion in today's money. The highway would have been called Interstate 101.

On January 20, 2012, the twin span box-beam bridges at the Indian River Inlet, constructed in 1965 during a major widening project, were replaced with a cable-stayed bridge similar in design to the Chesapeake & Delaware Canal Bridge.[6] The new bridge structure will allow both the State of Delaware and the U.S. Army Corps of Engineers to eventually dredge and widen the inlet.[7]

DelDOT improved the interchange with DE 1 and I-95 in Christiana. Traffic volumes have increased at the interchange, which is located near the Christiana Mall. The project included adding "fly-over" connecting ramps from northbound and southbound DE 1 to northbound and southbound I-95 which will allow for easier merging patterns and the elimination of lengthy backups on the former ramp design.[8][9] Construction of a new "ring access road" around Christiana Mall began in February 2011[10] and was completed in March 2012, with a newly built bridge over DE 1, just south of the I-95 interchange.[11] The ramp from southbound I-95 to southbound DE 1/DE 7 opened on August 27, 2013 and the ramp from northbound DE 1/DE 7 to northbound I-95 opened on October 17, 2013, with a ribbon cutting ceremony attended by Governor Jack Markell and DelDOT secretary Shailen Bhatt.[12][13]

Interchange numbering[edit]

Unlike I-95, I-495, DE 141, and the New Jersey Turnpike, which use a sequential exit system, or the Pennsylvania Turnpike, Atlantic City Expressway, and Garden State Parkway, which use a mileage-based system, the Korean War Veterans Memorial Highway segment of DE 1, along with the DE 9 and DE 12 interchanges, utilizes a kilometer-based system, in anticipation of a mid-1990s conversion of all measurements in the U.S. from the standard US measurement system to the metric system. All distance markers were in kilometers, as well as all exit numbers. In 2003, the distance markers were replaced with standard mile markers, but the exit numbers are still in metric. In addition, the exits north of US 13 in Tybouts Corner were in standard miles, reflecting DE 1 mileage from Ocean City, Maryland, but were converted in 1995 with the opening of the C&D Canal Bridge.[citation needed]

Some exit numbers, however, are incorrectly numbered for either miles or kilometers because they are offset by miles from a kilometer-based exit. Exit 86 is about 5 miles south of Exit 91, which is about 1 mile south of Exit 92 (the first correctly-posted KM based exit). Exit 98 should be Exit 99, and Exit 119 should be Exit 121 or 122 (it was incorrectly numbered from the opening of the toll-road, being 5 miles north of Exit 114).


As the main north–south state highway in Delaware, as well as the primary route to the Atlantic Seashore, DE 1 is currently seeing major problems with its existing infrastructure, most of which dates back to its 1978 inception. In addition to the building of a new cable-stayed bridge over the Indian River Inlet to replace aging twin box-beam bridges built in the 1970s, DelDOT has been rebuilding DE 1 between Dewey Beach and the Rehoboth Outlets, primarily to give DE 1 a "Main Street" feel, but at the same time, making improvements on underground utilities. At the US 9/DE 404 junction near Lewes, DelDOT is currently undertaking a widening project that will have DE 1 widened to a total of six lanes between the junction and DE 1A, relieving congestion to both beachgoers and those wishing to shop at the numerous outlet stores that dot the area.

Even on the toll road between Dover and Wilmington, there are plans to widen the highway between Tybouts Corner and I-95/Delaware Turnpike to six lanes, as a need to reduce congestion, as well as rebuilding the DE 1/I-95 cloverleaf interchange to one with high-speed ramps, allowing southbound and northbound traffic to access I-95 without having to "mix" in with merging traffic (the new DE 58 bridge over I-95, completed in 2006, being long enough to accompany the additional lanes). In addition to the expansion projects, plans are underway to build an "extension" of the highway, which will carry the US 301 designation, that will bypass Middletown and allow an alternative route to Baltimore, Maryland, and Washington, D.C., via the Chesapeake Bay Bridge, without having to travel on the heavily congested I-95/John F. Kennedy Memorial Highway on Maryland's Western Shore.

Other plans, including rebuilding DE 1 to a "semi-freeway" (similar in nature to US 301 in Maryland) have also been floated, but the future currently lies in the possible privatization of both DE 1 and the Delaware Turnpike, as well as the possible upgrading of the highway to an Interstate Highway route.[citation needed]

DelDOT has replaced several at-grade intersections along DE 1 with grade-separated interchanges. The intersection with DE 9 near Dover Air Force Base was rebuilt into an interchange in 2009.[14] In November 2009, construction began for a grade-separated interchange with DE 12 in Frederica; the interchange was completed in June 2011.[15][16] In November 2012, construction began on an interchange at DE 30 southeast of Milford. The interchange between DE 1 and DE 30 was completed in July 2014.[17] There are plans to replace several at-grade intersections with grade separated intersections along the route. They include Frederica Road in Frederica,[18] Bowers Beach Road in Little Heaven,[19] Thompsonville Road in Milford,[20] and DE 14 in Milford.[21]

Bannered and suffixed routes[edit]

DE 1A[edit]

Main article: Delaware Route 1A

Delaware Route 1A
Location: Dewey Beach-Rehoboth Beach
Length: 2.92 mi[1] (4.70 km)

Delaware Route 1A (DE 1A) is a state highway in Sussex County, Delaware. The route runs 2.92 mi (4.70 km) from DE 1 in Dewey Beach to another intersection with DE 1 west of Rehoboth Beach. The route provides access to Rehoboth Beach from DE 1, heading north before turning to the west. DE 1A follows King Charles Avenue, Bayard Avenue, 2nd Street (southbound), Christian Street (northbound), and Rehoboth Avenue.[22][23]

What is now DE 1A was originally a part of DE 14 between 1936 and 1942.[24][25] The road was designated DE 14A by 1966.[26] In the 1970s, DE 1A was designated along DE 14A for a few years before DE 14A was decommissioned in favor of DE 1A.[27][28] Between 2002 and 2006, a streetscape project revitalized the Rehoboth Avenue portion of the route and a roundabout was added at the entrance to Rehoboth Beach.[29][30]

DE 1B[edit]

Delaware Route 1B
Location: Rehoboth Beach
Length: 1.11 mi[1] (1.79 km)

Delaware Route 1B (DE 1B) is a state highway spur that allows access to and from Rehoboth Beach, Delaware. Formed in 1978, the route was originally DE 14B, but was renumbered when DE 14 was truncated to Milford, Delaware and DE 1 took its place.

DE 1B heading into Rehoboth Beach

A two-lane, residential-like road, DE 1B starts at the southern approach to the Lewes and Rehoboth Canal on DE 1 just 2 miles (3.2 km) south of the northern terminus of DE 1A. After crossing underneath of the high-level canal crossing, DE 1B then travels east for approximately one mile until it joins with DE 1A in the city's northern limits. Unlike the heavily traveled DE 1A, which is subject to the periodical opening of a double-leaf bascule drawbridge, DE 1B is lightly traveled, but yet serves as an alternate route because the road begins south of a high-level canal crossing.

Major intersections
The entire route is in Rehoboth Beach, Sussex County.

DE 1D[edit]

Delaware Route 1D
Location: Midway-Five Points
Length: 3.3 mi[31] (5.31 km)

Delaware Route 1D (DE 1D) is an auxiliary route of DE 1 in Sussex County, Delaware. It begins in Five Points at DE 23 south of an intersection with US 9 and DE 404. From here, it heads southeast on Plantation Road along with DE 24 Alternate. It then turns east for a brief concurrency with DE 24 before returning to DE 1 in Midway. This route serves as a partial by-pass of the outlet mall area of DE 1 southbound (beach-bound) traffic. The route is not marked from the northbound lanes of DE 1, and due to the left turn and jughandle accessing DE 1 north, it is not a practical alternate route for northbound traffic.[31]

DE 1 Business[edit]

Delaware Route 1 Business
Location: Milford
Length: 3.90 mi[1] (6.28 km)

Delaware Route 1 Business (DE 1 Bus.) is a business route of DE 1 that runs through Milford, Delaware. DE 1 Bus. starts at a partial interchange with DE 1 south of Milford. The route passes through the heart of Milford on Rehoboth Boulevard, where it intersects DE 36 first and then DE 14. The route then merges into U.S. Route 113 (US 113) at the north end of Milford before ending, along with US 113, at an interchange with DE 1.
