DE 11 begins at the Maryland border in western Kent County, where the road continues west into that state as MD 302 toward the town of Templeville.

From the state line, DE 11 heads northeast on two-lane, undivided Arthursville Road through a mix of woods and farms with occasional residences.

In the center of town, the route crosses DE 44 and heads north before it curves northeast out of Hartly.

DE 11 continues into rural areas with some residences, making another turn north.

[5][6] The portion of the route north of Hartly was built as a paved state highway in 1927.
