Georgia DOT is taking public input on a plan to widen SR 21 from south of Cook Street in Chatham County to north of McCall Road in Effingham County. The proposal would rebuild the corridor as a six-lane, median-divided highway with intersection improvements. The state lists right-of-way work in 2027 and construction in 2029, with a current construction estimate of about $99.2 million.
Why it matters
The project targets capacity and safety on one of the region’s main north-south commuter and freight corridors.
What to watch
Watch for right-of-way work scheduled for 2027 and the construction phase currently listed for 2029.
