I feel like I can't possibly be the first one posting about this, but my limited DDF search skills haven't turned up anything, so here goes nothing with a new thread. I flew LGA-MCO with United this week, and seeing some of the updates to terminal B and eastern concourse made me go down the rabbit hole of what's changing at LGA. They have a site that has some info (
https://www.anewlga.com/), but it's certainly not comprehensive.
From what I can tell, terminal B (formerly known as central terminal building going back even farther) used to look like this - an eyebrow shaped building, with 4 concourses A-D and a parking garage in the big circle area south of it (GCP bordering south of that). Beyond the horrendous and dated traveler experience, the roads in/out/around were a tangled mess that were always mired with traffic.
They started the revamp as far back as March of 2016. At this point, they've added a single, much larger parking garage for terminal B to the left of the parking garage in the pic above, mostly in former parking lots. They demoed the old garage, and put in a brand new departures and arrivals hall using up that space, which opened this past summer. The roads have been streamlined and set up to accommodate all of the changes they're making. They built a brand new eastern concourse (mostly where the old concourse A was) with a few more gates than the old A-B combined, which is connected to the new departure/arrivals hall via a large skybridge that they're planning on having planes taxi under (a first apparently?). They also just opened some gates of a brand new western concourse this past summer (mostly where the old C was). That portion, as well as concourse D (which is still active) is accessed for now by first going through the new departures/arrivals building, then what remains of the old terminal building. Eventually, once the old departures/arrivals building and remaining old concourse structures are torn down, the western concourse will also be connected directly to the new departures/arrivals building via a large skybridge that planes can taxi under it.
This is all for terminal B, but they're doing similar things with Delta's terminals - building a new unified terminal C. On that side, they've completed the new parking garage for C, and begun construction on the departures/arrivals hall. The first new concourse (G) is done as well (currently connected to the existing terminal D building, but will eventually connect to the new C obviously). A 'central hall' connecting the eventual new B and C is under construction as well, such that you'll technically be able to walk indoors through the entire airport eventually. There are also plans for an Airtrain of some sort, but it doesn't sound all that helpful based on what they're planning.
The current setup looks like this:
As to the actual experience, the departures hall was really nice - a true modern airport feel, very un-LGA-like. TSA had this automated bin system that appears to move things along a little faster, including for flagged items. I liked the water feature (fountain/light show thing) you pass by on the way to the gates. All in all, a very pleasant surprise for me. Didn't take many pics/vids myself, so here's their 'tour':
