I landed back at LGA today, and before heading home I went over to take a look at the progress on the renovations to the 60s gates, the easternmost concourse.

I took the pic below. It appears they’ve started the re-facading of the concourse as you can see on the left. I believe they won’t demolish anymore of it, but hopefully they replace the glass. It seems delta is also trying to preserve some of the jet bridges.
