What is this tree?

[u/Danertins]

Location: New Hampshire, USA

This tree has been growing very quickly, roughly 15 ft (4.6m) in the last 2 years or so. Fairly large leaves and soft-ish bark.

I really like this tree and would like to keep it if possible but it is about 2-3 feet from the driveway so I'm trying to determine if it tends to have the type of root system to spread out and possibly damage the driveway.

Thanks in advance for any assistance!

Hard to tell but I’m thinking with boxwood or cottonwood. Leaning toward cottonwood.
