There was this road by my house that I ride a few times a week, and I saw them ripping up a mile long section of it one day. The road was in pretty good shape, but I was excited for it to be super smooth. Got to ride it a week later and it was HORRIBLE! So badly wash boarded and rough that I ride right next to the center line. The right half of the lane looks like the moon. They didn't do any work under the road or anything, so I am not sure why they "repaved" it. The old road was WAY better.
I'm jealous of your smooth new road.
