Traveling nearly 43 miles across southern Sussex County, SR 20 joins the city of Seaford with Millsboro and beaches from Fenwick Island north to Bethany Beach. The state route is mostly rural outside of the population centers. The lone four lane segments along the route are located in Seaford and along the overlaps with U.S. 13 (Sussex Highway) and U.S. 113 (Dupont Boulevard).

SR 20 (Stein Highway) extends east from the end of MD 392 at the community of Reliance. The state route initially through farm land before entering Seaford at Chapel Branch. Stein Highway expands into a five-lane commercial boulevard across the city to Front Street (old U.S. 13 Alternate). Norman Eskridge Highway continues the route east to the 0.84-mile overlap with U.S. 13 (Sussex Highway) south.

U.S. 13/SR 20 (Sussex Highway) cross Williams Pond and the Nanticoke River south to the town of Blades. Concord Road then leads SR 20 east by a series of residential streets along Deep Creek to the community of Concord. The route shifts southeast from there to cross U.S. 9 at Hardscrabble Road.

Hardscrabble Road takes SR 20 east to Jones Crossroads, Workmans Corners and the original end at U.S. 113 on the north side of Millsboro. A 3.12-mile overlap with U.S. 113 takes the state route through Millsboro, where it branches southeast to the town of Dagsboro.

SR 20 zigzags through Dagsboro, briefly overlapping with SR 26 along Main Street and Vines Creek Road. Leaving the town limits, SR 20 angles southeast through the rural communities of Omar and Roxana to Johnson. Suburban development accompanies the route on Zion Church Road to its merge with SR 54 (Lighthouse Road). SR 20/54 then overlap for 3.96 miles to their joint termini at SR 1.

The alignment of SR 20 appeared on the 1936-37 Official Delaware Highway Map between Reliance and U.S. 113 outside Millsboro. Through Seaford and Blades, the state route turned south along Front Street between Stein Highway and High Street. High Street continued the route east to Concord Road at U.S. 13. The alignment along Norman Eskridge Highway to U.S. 13 was added by 1970.

The Delaware Department of Transportation extended SR 20 east from Millsboro to Fenwick Island in July 1991 to provide another signed route for resort traffic. Travelers bound for the Bethany Beach and Fenwick Island area were encouraged to follow U.S. 13 south from Bridgeville to SR 20 at Seaford to avoid a congested stretch of SR 404 east through Georgetown.1 Beyond the new overlap with U.S. 113, SR 20 overtook previously unnumbered roads southeast to Fenwick Island.
