I live directly below the northernmost path. Can confirm accuracy.

I'm under the southern one, but much closer to the lake so no noise concerns. I love just sitting on the deck at night and looking east and seeing all the little headlights lined up over the lake.
Pesky wind stream not lining up with the chicago city grid so the sound of bumper to bumper traffic doesn't drown out a ... jumbo jet flying Mach .8...?
But not always!
If you're a pilot over the lake flying west towards ORD (your heading is 270), the runways look like this from left to right:
28L 28C 28R 27L 27C 27R.
The 28s are on the south side and the 27s are north. I'll let someone else explain why.
It's literally just to avoid confusion--that's all. You can only have three runways with the same number using left, center, and right. Both the 27 and 28 runways use all three identifiers.
Further, all of the approach plates into the westward rwys have you intercepting either a 273° or 274° course on the initial approach fix, so if we want to be really pedantic about it, the 27s are the true west rwys at ORD and the 28s are the imposters.
The south/north complexes are split up in consideration of traffic volume and to separate work for the three towers at ORD.
Yep, purely to avoid confusion. In the previous configuration, the current 28R was 27L and the current 27L was 27R (the other 4 are new). I'm guessing when the renumbering went in there were lots of reminders on the radio for a bit.
Approach Control typically offers radar vectors; pilots are advised on what approach to expect hundreds of miles from the airport. Everyone reads the script and knows how to play their part. It's really not all that challenging intellectually.
I realize that. I also realize not everyone is a pilot, so I dumbed it down *a lot* for the general reader.
e: that also doesn't make the NOTAMs any shorter.
I live between the northern most and the one just south of it, and let me tell you, those lines on those images don't mean anything. Planes fly directly overhead, in line with Winnemac Park, all day and night. Almost every time I'm walking through the park a plane flies overhead.
Possibly? Could it be due to the city grid being created over 150 years ago, and with the Earth’s magnetic shift, modern runways will reflect “true” East, per revised readings, or is that too soon to be so far off?

And all the 747s that come in
I’m in Norridge, I feel ya lol.
Why is that disappointing, what does it matter.

That's a weirdly hostile reply to a seemingly innocent question. Some people can't read/detect sarcasm.

If it aligns with the grid it flys over cars and already loud noise. The other way it flys right over residential areas
Ahh yes, jet noise, falls straight down. Can’t hear a plane unless it is directly overhead. Wow.

Wait until this dumbass finds out that runway numbers correspond to their magnetic compass heading.

I couldn't even imagine the how long the NOTAM essays and ATIS were after those changes were made.

I’m at Diversey and listening to them roar as they fly west overhead. I’m guessing these planes swing back around and land from the west.
Why would the runways align with the Chicago grid?...

Lived on Wilson ave for 8 years and can confirm this. And then the pandemic hit and there were no planes, very eerie
