I can only imagine it as a good thing, even if Atlanta is footing 100% of the bill for street maintenance. There's Federal funding, SPLOST, improvement districts, and other sources for improvement and maintenance. It's been a complete headache for neighborhoods to have little to no control. Five lane one-way streets with horrible sidewalks will give way to three lane streets with a bike lane and wide shaded sidewalks, and the city can more easily do things like fix signal timing, install pedestrian crossings, and require construction sites to provide ADA access if they close the sidewalk.
Side note, but it really irked me when they named West Peachtree honorary Gladys Knight Highway. I know it doesn't matter, but it showed GDOT's tone deaf attitude. How hard would it have been to call it "Gladys Knight Way" or "Gladys Knight Avenue"? May seem irrational but it still bugs me.
