Interstate 516 Guides
Originally designated as Georgia 26 Loop, Lynes Parkway was redesignated as an extension of Georgia 21 in 1979 and added to the Interstate system in 1985. U.S. 17 and 80 were both realigned to share segments with Interstate 516 & Georgia 21 at that time: U.S. 17 followed the freeway north from Ogeechee Road to Main Street through Garden City. It was realigned again in 1988 away from Garden City and onto I-16 to the Talmadge Bridge. U.S. 80 joined the freeway from Bay Street and Augusta Avenue southward to Ogeechee Road east.
DeRenne Avenue was extended west from Montgomery Street to ACL Boulevard by 1967, with construction of W.F. Lynes Parkway north to Interstate 16 complete by 1968. Work on the freeway progressed from I-16 north to Augusta Avenue by 1970. The interchange with Bay Street and curved routing northwest into Garden City was added next by 1979, followed by the four-lane alignment west to Burnsed Boulevard (Exit 8) in 1983.1 Georgia 421 was assigned to Interstate 516 as a reference number in 2000 (All Georgia Interstates have a 400-series counterpart).
