On a Vail Daily article from July 20th, it said "As of mid-July at [the] Avanti Express [lift], crews have removed the lift terminals and the cross arms of the old lift. Assembly of the new arms for the six-passenger chairs is ongoing, and in the next few weeks, a helicopter will be installing those onto the towers, said Sara Lococo of Vail Mountain communications. Work on Chair 2 is expected to be finished in time for the winter season." So, from the way that paragraph is worded, I think it says that the Avanti Express lift will reuse tower tubes from the original lift. And, the Avanti Express lift is not just the only addition being built: Vail's also building an alpine coaster to the west of the Pride Express lift, and a zipline canopy tour around Game Creek Bowl. There is even a photo on a Twitter feed called @vailliftops that is of the Forest Flyer coaster:

It's a bit off topic, but I thought it was somewhat relevant.
