10th street is really on the up-and-up.
The structure is in place for the GA Tech building on 10th right next to the under-renovation basketball arena. If I recall correctly, it's a gym expansion, possibly for the golf team? This part of 10th street will look a lot nicer once these buildings are finished and their plazas are open.
Hilton/Homewood hotel is still trucking along, and should be finished soon. Unfortunately the east-facing facade is a huge blank wall. But when coming from the west, it helps to create a little bit of a "canyon" along 10th street. There will be streetfront restuarant/retail space fronting 10th.
Also at the NE corner of 10th and Peachtree they've done quite a bit of demolition/renovation on the little building there to put in a high-end neighborhood grocery store. The old covered patio area is completely torn out.
The new mid-block crosswalk on 10th in front of the MARTA Midtown Station will indeed have a rapid flash beacon
. So when pedestrians push the button to cross, a rapid flashing yellow light alerts drivers. It's not 100% effective (like a red light would be), but it is much cheaper (about $10,000 to install) and has a high compliance rate from drivers.
The transformation of the old Hotel Midtown into Hyatt Midtown is in full swing. There's scafolding up around most of the building. Street-level restaurant entrance will be added on 10th street.
On top of all of this, the sidewalk improvements so far look really nice. Much wider and with nice granite curbs and faux-brick inlays. They should be installing pedestrian-oriented streetlights and planting trees soon. Construction is proceeding eastward; I can't wait until they fix the sad stretch from Juniper to Piedmont.
