7. 3 WTC Will Have Digital Wayfinding in its Staircases and Hallways

3 WTC is possibly the first building to make use of a new innovation: digital wayfinding screens both in the stairwells and in the hallways to help people orient themselves. Given that there’s 2.5 million rentable square feet of space in 3 WTC, it’s probably going to be helpful! The anchor tenant at 3 WTC will be the advertising firm GroupM, which will take 700,000 square feet on 14 floors.
