DelawareRoute 23 is a state highway in Sussex County, Delaware. Its southern terminus is at Massey's Landing in Long Neck, near the confluence of Rehoboth Bay and Indian River Bay and its northern terminus is at the Five Points intersection, where it ends at U.S. Route 9, DE 1, and DE 404. From the southern terminus, the route runs west through residential areas of Long Neck before heading north through rural areas with some development. DE 23 is concurrent with DE 5 between the DE 24 intersection in Long Neck and Fairmount. It is also concurrent with DE 24 Alternate between Hollymount and the DE 1D intersection in Five Points. The road was designated as part of DE 22 south of Fairmount for a short time in the 1930s, with DE 5 designated along the stretch between DE 24 and Fairmount by 1938; the remainder of the road was unnumbered. The road was fully paved by 1970. The DE 23 designation was assigned by 1994.
Route description
DE 23 begins at a boat ramp parking lot at Massey's Landing in Long Neck, near the confluence of the Rehoboth Bay and the Indian River Bay. From here, the route heads west on two-lane undivided Long Neck Road through a mix of residential areas and marshland between Rehoboth Bay to the north and Indian River Bay to the south. The road winds west through homes, commercial development, and a few farms, passing south of the Baywood Greens golf course. Farther west, DE 23 comes to an intersection with DE 5/DE 24. At this intersection, the name changes to Indian Mission Road, and DE 23 begins a concurrency with DE 5. The two routes head northwest and cross Guinea Creek, passing through a mix of farmland and woodland with some housing subdivisions. In Fairmount, DE 5 splits to the northwest and DE 23 continues north on Beaver Dam Road. In Hollymount, DE 23 intersects DE 24 Alt. and forms a concurrency with that route, with the road curving northeast and crossing Bundicks Branch. In Five Points, DE 23 intersects DE 1D and turns to the north, with DE 1D/DE 24 Alt. continuing straight and curving to the southeast. A short distance later, DE 23 intersects US 9/DE 404 and turns east-northeast to join those two routes on the four-lane divided Lewes Georgetown Highway. DE 23 reaches its northern terminus at an intersection with DE 1, at which point DE 404 also ends and US 9 turns east to join DE 1. At this intersection, access from northbound DE 23 to northbound DE 1 is provided by a reverse jughandle. Past this intersection, the road becomes US 9 Business. DE 23 has a total length of. The route has an annual average daily traffic count ranging from a high of 14,359 vehicles at the northern terminus at DE 1 to a low of 1,740 vehicles at the south end of the DE 24 Alt. concurrency. The small portion of DE 23 that is concurrent with US 9/DE 404 is part of the National Highway System.
History
By 1920, what is now DE 23 existed as an unimproved county road. The portion of the present route that is concurrent with DE 5 was upgraded to a state highway by 1931. DE 22 was designated in 1936 along the portion of present DE 23 south of the DE 5 intersection in Fairmount. By 1938, DE 22 was decommissioned, with DE 5 designated on the portion north of DE 24 while Long Neck Road south of there became unnumbered. By 1970, the road was paved. DE 23 was assigned onto its current alignment by 1994. DE 24 Alt. was designated to run along DE 23 between Hollymount Road and Plantation Road by 2006. In 1991, the Five Points intersection was reconfigured to separate the DE 23 and Plantation Road intersection from US 9/DE 404, with a short connector road linking US 9/DE 404 to the two roads. In addition, a jughandle was constructed from eastbound US 9/DE 404 to northbound DE 1. There are plans to reconfigure the intersection between US 9/DE 404 and DE 1D/DE 23 that would realign DE 1D and DE 23 to intersect a longer connector road linking to US 9/DE 404 and build a direct ramp from southbound DE 1 to US 9/DE 404 at the DE 1D/DE 23 intersection. This project is currently in the design phase with construction planned to begin in 2024.
