With extensions north to New Castle County made by 1990 and 1993, Delaware 15 represents the third longest state route in the system. The original alignment leads northwest along Canterbury Road, from Delaware 14 and the city of Milford, to U.S. 13 (Dupont Highway) near Viola. The initial extension brought Delaware 15 north to U.S. 301 and Delaware 299 in Middletown. The second addition parallels U.S. 301 through rural areas west of Mount Pleasant to Summit Bridge.
Delaware 15 Highway Guides
SR 15 (Canterbury Road) ventures north from Milford through a varying landscape of subdivisions and farm land to the community of Canterbury and U.S. 13. Following a brief overlap with U.S. 13 (Dupont Highway), SR 15 shifts west onto U.S. 13 Alternate (Upper King Road) 1.76 miles to SR 10 Alt (Main Street) in the town of Woodside. The two routes combine west along a short concurrency to Dundee Road, where SR 15 resumes a northerly course.
Delaware 15 passes through southern reaches of the Camden town limes through to Delaware 10 and Moose Lodge Road. Moose Lodge Road continues the route north to suburban areas on the west side of Wyoming. An eastern turn brings Delaware 15 into the the Wyoming town center via Westville Road and Southern Boulevard. Railroad Avenue then extends the route north to Wyoming Mill Road and the city of Dover.
Through Dover, SR 15 forms a loop along preexisting roads. Hazlettville Road and North Street lead SR 15 east by the Kraft Heinz plant and other industrial businesses to Saulsbury Road. POW/MIA Parkway, constructed from 2015 to 2017, ties into that intersection from the south, as SR 15 advances north along McKee Road. North of SR 8 and Walker Road, SR 15 (McKee Road) splits from Scarborough Road as it arcs northeast to U.S. 13 and SR 1.
Delaware 15 takes a number of turns from Wyoming to Kenton through the city of Dover.
Leading away from Dover, SR 15 doglegs through a mix of subdivisions and forest land along Denneys Road west and Kenton Road north. Kenton Road extends SR 15 north 1.7 miles to SR 42 west near Moores Corner. The two state routes overlap for 1.2 miles to Brenford Road at Seven Hickories. SR 42 continues west to SR 300 at Kenton while SR 15 arcs northward onto Friendship Road to also meet SR 300 (Wheatleys Pond Road).
A brief overlap with SR 300 shifts SR 15 slightly east to Alley Corner Road. Alley Corner Road joins SR 15 with SR 6 (Millington Road), where the two merge east for 1.3 miles to Duck Creek Road in the town of Clayton. SR 15 then travels north from there across Providence Creek into New Castle County.
The convoluted alignment of Delaware 15 continues northward through rural portions of southwest New Castle County. Passing through the settlements of Greensburg, Dexters Corner and Taylors Corner, as well as swaths of Blackbird State Forest, Delaware 15 emerges through growing areas of south Middletown along Levels Road. Combining with U.S. 301 & Delaware 299 (Middletown Warwick Road), Delaware 15 angles northeast one mile to the intersection of Main Street and Bunker Hill Road west of Downtown Middletown. Delaware 299 departs U.S. 301 for Main Street east while Delaware 15 turns northwest on Bunker Hill Road and Choptank Roads.
Choptank Road leads Delaware 15 north by a number of large lot subdivisions through to Delaware 286 (Bethel Church Road). Bethel Church Road brings the state route back to U.S. 301 & Delaware 71-896 at Summit Bridge.
