Opening the bridge closed the ferry service from New Holland to Hull.
Several years before the bridge opened the last coal burning paddle steamer in the UK (the Lincoln Castle ) was retired.It was replaced by a diesel driven ship. The Lincoln Castle was dragged to Grimsby and used as a floating restaurant until a plate inspection deemed her no longer seaworthy(even stationary in a dock)
