BridgeMuseum

This guide to the BridgeMuseum in Sydney centers on an Irish-born ironworker named Vincent Kelly, out on the bridge's unfinished road deck the moment the surface gives way beneath him, with nothing below but open air and the harbour. It also traces the sixteen other construction workers whose names are recorded inside the very pylon you're standing in, and explains why this stone shell was bolted on after the fact, though it never held up a single ton of steel.
