Any pictures?
I believe they quit for awhile due to aesthetics reasons. As a visitor I could care less about what the sidewalk looks like as long as it is functional. It was way better walking around last year than when we were there in 2012.
Good to hear they are continuing. Pavers on to of concrete should last a long time and remain fairly flat but will never been as smooth as concrete. I wonder why they didn't use a colored or stamped concrete, if it is even available there.
