When last we checked in with the ongoing construction work at the High Line, concrete was flowing above 19th Street, while Andre Balasz was getting his crane on. Nearby, a tipster files this fresh report: "They seem to be doing so sort of sanding or re-coating of the high line. (on the right side of the photo you can see the refinished/repainted portion.) you can tell that whatever they're doing is kicking up some serious fumes. everything is cloaked and sealed off tight."
