State Route 21 (SR 21) is a 85.9-mile-long (138.2 km) state highway that runs southeast-to-northwest through portions of Chatham, Effingham, Screven, and Jenkins counties in eastern part of the U.S. state of Georgia. The route connects Savannah to the Millen area, via Sylvania. The route is part of the Savannah River Parkway and is being considered for inclusion into Interstate 3.

Route description

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

SR 21 continues north, leaving Chatham County and entering Effingham County. The route passes 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 around Sylvania, SR 21 continues west into Jenkins County. East of Millen, SR 21 turns to the north at its intersection with SR 67, then arcs to the northeast of Millen to meet its northern terminus at US 25/SR 121. SR 21 is being considered for part of the proposed I-3.

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

In 2000, the Georgia General Assembly passed a resolution^[2] to designate this portion of SR 21 in honor of Tom Triplett,^[3] 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.^[4]^[5]
