$4.5 billion project on SR 400 to add toll lanes should start later this year and be completed in 2031! Get ready for six years of construction along this corridor!

OMFG, 6 years! Cheesewhiz! I hope its 2 toll lanes in each direction? Most of the interchanges over 400 are needing to improvements or need to be rebuilt!

Looks like clearing and grubbing have started on the west 20/285 interchange, trees are coming down

The tentative opening date for the southbound I-285 to eastbound I-20 flyover is May 14th.

I take it that would be the eastern interchange?

Yes. Work has barely started on the west side.

On an unrelated topic: Years into the construction of improvements to the I-85-North Druid Hills Road interchange, I finally realized why it's configured the way it is. To me, building a braided ramp (shown in green) to improve access to the northbound frontage road seemed like overkill, though it will improve access-- including for ambulances-- to the enormous children's hospital nearby-- and possibly divert some traffic from the Clairmont Road offramp, which backs up alarmingly onto the mainline during the PM peak hours.

After the DLT ramp (in gold) was opened in March, I realized it'd remove the need for one signal phase from the intersection at the west end of the bridge. When the green ramp opens, it'll remove the straight-through movement from the northbound offramp onto the frontage road. Together, the new ramps will free up a significant amount of green time for North Druid Hills, the off- and onramps, or both. I think it's rather clever, and I find it annoying that GDOT hasn't bothered to explain this in their public outreach.

GDOT needs to Gut the Clairmont Rd interchange under IH 85 and convert it to a SPUI, like the ones seen on P.I.B. and Jimmy Carter Rd in the Norcross area. The traffic on those Frontage roads at Cliarmont can back up onto the interstate in the evenings...

The existing N. Druid Hills overpass has always bounced a lot which I know doesn't mean it's failing structurally. It is about 35 years old, and one time I thought I saw it on a list of overpasses that would be replaced. Does anyone know if that's true or is it totally not necessary?

I hounded GDOT in the early 2010s to replace the little overhead green signs on the access roads because so many had faded to blank. They finally did and a woman emailed me from that division's offices. I feel that I made a difference. Brookhaven, after it became an official town, replaced a few of them on the West side access road identifiable with a curve in the arrow diagram on the signs.
