The state might consider building an outer beltway instead.
The suburbs of Atlanta sprawl and there are possible paths that an outer beltway could be put through.
The outer perimeter was all designed in the 90s and conceptually ready to go. Was going to be GA 500 . I purchased a house in prime position to be exactly halfway between each loop, but it never happened.
Years ago, an outer beltway was proposed with a promise of only 4 exits so it wouldn’t get congested like 285. Those exits were Lawrenceville, Cumming, Canton and Cartersville.
A few years later, and it was promised only 7 exits. A few years later it would be no more than 13 exits.
Point being, developers started looking at development and were buying the politicians.
Resistance was fierce and eventually the idea was dropped.
If one is built, it will be just as congested over time as the current 285, without solving the problem it was built to solve.
