Route description
DE 1 begins at MD 528 at the Maryland state line in Fenwick Island, where it heads north along a multilane divided highway called Coastal Highway through the Delaware Beaches resort area along the Atlantic Ocean, crossing the Indian River Inlet on the Indian River Inlet Bridge. In Dewey Beach, the route turns northwest away from the ocean, running through commercial development from Rehoboth Beach to Nassau. DE 1 forms a concurrency with US 9 from Carpenters Corner to Nassau. Past Nassau, DE 1 leaves the Delaware Beaches resort area and runs northwest through rural areas in northern Sussex County. The route bypasses Milford to the east along the Milford Bypass, crossing into Kent County. After an interchange with the northern terminus of US 113, DE 1 heads north along Bay Road through more rural areas, passing east of Frederica. The route becomes a freeway near Magnolia and turns into a toll road called the Korean War Veterans Memorial Highway while passing Dover Air Force Base. DE 1 bypasses the city of Dover to the east and begins to run parallel to US 13. The route passes east of Smyrna and enters New Castle County, where it crosses US 13 multiple times and heads west of Odessa. The road has an interchange with the northern terminus of the US 301 toll road in Biddles Corner. The toll road portion of the route ends before it crosses the Chesapeake & Delaware Canal on the Senator William V. Roth Jr. Bridge in St. Georges. DE 1 becomes concurrent with US 13 from Wrangle Hill to Tybouts Corner, where US 13 splits to the northeast. The DE 1 freeway heads north and meets US 40 in Bear before it comes to Christiana, where DE 7 joins the route. The DE 1 designation ends at an interchange with I-95 and DE 7 continues north along the freeway to the DE 58 interchange, from which point DE 7 turns into a divided highway with at-grade intersections.DE 1 serves as a major route connecting northern Delaware to the Delaware Beaches and sees heavy traffic in the summer months. The peak travel periods in the summer are southbound on Friday evenings, both directions on Saturday afternoons, and northbound on Sunday afternoons. DE 1 serves as a primary hurricane evacuation route from the Delaware Beaches and points along the Delaware Bay to inland locations in northern Delaware. The sections of DE 1 between DE 12 near Frederica and Clapham Road in Little Heaven and between Trap Shooters Road near Magnolia and DE 9 near Dover Air Force Base are designated as part of the Delaware Bayshore Byway, a Delaware Byway and National Scenic Byway. The section of DE 1 between the south end of the DE 7 concurrency and the northern terminus at I-95 in Christiana is part of the Washington–Rochambeau Revolutionary Route, a National Historic Trail. DE 1 has an annual average daily traffic count ranging from a high of 116,110 vehicles at the US 13 interchange north of Smyrna to a low of 10,590 vehicles at the southern boundary of South Bethany. The entire length of DE 1 is part of the National Highway System, a network of roads important to the country's economy, defense, and mobility.Dover Air Force Base to Christiana

DE 1 runs north along the west side of Bay Road before it passes over it, where there is a southbound exit and entrance and a northbound entrance that serves to provide access to DE 10 from southbound DE 1 and to northbound DE 1 from DE 10. Immediately after this is a southbound exit and northbound entrance with the Puncheon Run Connector freeway, which heads west toward US 13. The freeway continues north along the eastern edge of Dover and comes to a southbound exit and northbound entrance at DE 8, which provides access to downtown Dover to the west and the town of Little Creek to the east.

DE 1 heads north and closely follows along the west side of US 13 as it runs through more rural areas with residential development to the east. The freeway turns northwest away from US 13 and crosses the Appoquinimink River, passing to the northeast of a residential neighborhood before coming to a diamond interchange with DE 299, which provides access to the town of Middletown to the west and the town of Odessa and US 13 to the east. Past this interchange, DE 1 curves northeast and passes over US 13 again before it turns north and crosses Drawyer Creek. The freeway continues north a short distance to the east of US 13 past residential subdivisions as it comes to a diamond interchange with Pole Bridge Road, which heads west to intersect US 13 and the southern terminus of DE 896 in the community of Boyds Corner.
