Advertisement Plans to install brightly-lit billboards on a footbridge in central Sydney have triggered tensions between the owners of a heritage-listed pub building and the NSW government, which is pushing to erect more of the signs across the city to raise revenue for the stateâs transport agency. Sydney Trains is pursuing plans to attach 12-metre by three-metre digital advertising billboards to both sides of the Wynyard Walk pedestrian bridge that goes over Sussex Street and links Barangaroo to the western side of the CBD. Bill Lloyd, 69, has owned his terrace in the same building as the Sussex Hotel, next to Wynyard Walk, since 1992.
