I worked as a labourer on the Anglican Cathedral in 1978 and 1979. They were hurrying to get in finished for the official opening in 1978. In 1979 I was back laying paving stones on the roadway to the north end. The paving stones came from the old platform of Exchange Station and lay under ashphalt for decades, so they were in perfect condition. Some of them were six by four foot and five or six inches thick.
