We've got a few of those here in wisc the two Ive been on aren't paved tho, one is pretty cool the Elroy Sparta trail. Over in the lacrosse area getting into the hills and bluffs of the state, where they reached a hill that would be to steep for a train the blasted a hole thru it think there are 4 tunnels on it? Which are great to go thru on a hot summer day. Also they are putting in a bypass of the hwy that runs from my home town 50+ miles north when it's complete there will be a paved bike trail that goes from on end to the other
