US 89:
I wish they’d reconstruct the western 285/20 interchange first. That one has far worse traffic issues in my experience.
Finrod:
I wonder when they're going to eventually reconstruct I-20 west of downtown out to I-285. That road felt ancient and like it could fall over any time when I was commuting on it eight years ago. I imagine the railroad underpass complicates things quite a bit.

I've never heard of any such project, and I don't know what railroad underpass you're referring to. Perhaps you're mistaking the Westview Drive bridge for a railroad bridge because the girders are so deep.
In case you don't know, I-20 west was originally built with the same cross section as I-20 east and the last section of I-75-85, with six concrete lanes,* a tall-curbed grassed median, mountable curbs between the mainline and the right shoulders, and no shoulders on the mainline bridges. In the early eighties, GDOT installed a modern Jersey barrier median and flush-paved shoulders, added shoulders to the bridges, and tidied up the concrete with the intent of leaving it as six lanes. However, shortly before project completion, they decided to pave the whole thing with eight lanes of asphalt and accept painfully narrow shoulders. I really thought it'd prove to be unacceptably unsafe, but I guess I was wrong.
*Those original six lanes on concrete are still visible on I-20 east. I thought not replacing them when I-20 was widened was a mistake, too, but I was wrong about that as well.

I removed my post from earlier today about the supposedly-imminent opening of the new DDI at GA 400 and Abernathy Road. In fact, there are mast arms that haven't been installed yet, and some that have been installed don't have bagged signal heads on them.
What did happen over Friday-Saturday night is the temporary diversion of all eastbound traffic to 400-Glenridge and Roswell Road to the one-lane permanent Roswell Road offramp, which, of course, has been striped as two lanes by commandeering the shoulder. I'm a bit surprised that both of the right lanes of 285 are dropped there rather than having an option lane as was done at the previous 400-Glenridge offramp. Doing this moves the point at which the mainline reduces to three lanes a good mile-and-a-half upstream. A member of our Georgia roads Facebook group posted a video of his trip down the new offramp, but I was curious enough about the mainline and the DDI to check it out myself (plus the weather was gorgeous and I wanted to try out my new phone camera!).
The fourth lane is reopened a little before the Roswell Road bridge, which means that traffic from the onramp from Roswell Road still has to merge into it, then move left again to remain on eastbound 285.
Also, in the westbound direction: I'd thought that the onramp from Glenridge to 285 added a permanent fourth lane to the 285 mainline, same as the Peachtree-Dunwoody onramp does eastbound. Either I was wrong, or it's been changed. Now, the combined westbound CD and the Roswell Road onramp add two lanes to the now-three-lane mainline, with the former fourth lane ending upstream somewhere. If someone can clarify that, I'd appreciate it.
EDIT: The reason for this detour is that they're replacing the decks on the bridges over Long Island Drive and Lake Forest Drive. that means that they'll shift traffic to do the rest of the bridges at some point.

Millions to add lights in a tunnel?
Crazy.
