Route description

SR 21 begins at an intersection with SR 204 (Abercorn Street) in Savannah. The highway travels to the west-northwest, becoming a freeway, and gains the designation of Interstate 516 (I-516) and the unsigned SR 421. The highways continue to the west-northwest, then curve to the north-northeast at the interchange with Veterans Parkway. At exit 3, US 17/SR 25 join the freeway from the southwest, and US 80/SR 26 join the freeway from the northeast. Continuing to the north-northeast, the highways have an interchange with I-16, at which point, US 17 departs to the east-southeast, concurrent with I-16. At exit 7, US 80/SR 26 depart to the west-northwest, and the highways turn to the west-northwest. After an interchange with SR 25, I-516/SR 421 end, and SR 21 continues its northwestward route. In Port Wentworth, SR 30 joins the route; north of their interchange with I-95, SR 30 departs to the west-southwest.

SR 21 continues north, leaving Chatham County and entering Effingham County. The highway travels through Rincon and Springfield, then continues northwest, through rural parts of the county, and continues into Screven County. After a brief concurrency with US 301/SR 73 Loop around the western side of Sylvania, SR 21 continues west into Jenkins County. East of Millen, SR 21 turns to the northwest at its intersection with SR 67, then arcs to the northeast of Millen to meet its northern terminus at US 25/SR 121.

Tom Triplett Parkway

The Tom Triplett Parkway is a section of SR 21 located in Port Wentworth on the west side of the Savannah metropolitan area.

It stretches from the Chatham–Effingham county line (roughly the Lake Cherie Road intersection) to the Garden City–Port Wentworth city line (roughly the SR 307 intersection).

In 2000, the Georgia General Assembly passed a resolution to designate this portion of SR 21 in honor of Tom Triplett, a Democrat who served as Mayor of Port Wentworth and as a State Representative for 18 years. Tom Triplett died in 2006, at 71 years of age.

National Highway System

All of SR 21, except for the Millen Bypass, a bypass around the northeast part of Millen, is included as part of the National Highway System, a system of roadways important to the nation's economy, defense, and mobility.

Future

SR 21, as part of the Savannah River Parkway, is proposed to become part of I-3.
