Lift Bridge, Barnby Dun, Doncaster
This was built in 1983 to replace the original (1900) swing bridge. It is built of steel and powered by electricity. The replacement work cost £0.5 million and was part of a wider upgrade of the Navigation to conform to the 700-tonne Eurobarge standard (see Later Development section of this article). An elevated control house was built for the sole use of operational staff, but in recent years a freestanding low level standard control console has been built for the use of boaters when the bridge is not staffed. Sykehouse Lift Bridge (downstream of Barnby Dun) was built to the same technical specification. The structure is sturdier than might be expected for a bridge that carries an unclassified road linking Barnby Dun and Bentley, but it was the only way for abnormal loads to access the nearby Thorpe Marsh power station, so the bridge was designed for loads of up to 180 tons gross weight. Although Thorpe Marsh Power Station has now been demolished, the bridge is still busy with road traffic. This is because it is one of the few crossings of the Navigation in this area.
