Nope, no roundabout! It was one of the proposed options, but they went with an alternative.
King from Fountain to Riverside Park is being restructured to increase the curve radius around the flour mill for better visibility (and I think is getting an MUT?),
King in front of the old hotel is getting a right turn lane onto Fountain (heading up the hill)
Fountain from Shantz to King is getting a second Eastbound lane
The Shantz intersection is being moved up the hill, and gaining (I believe) a second left turn lane onto Fountain Eastbound, and a right turn lane onto Fountain Westbound.
Edit: Ah, here we go!
And in even more detail
