 A gated railway crossing and keeper's lodge was built at the Quarterbridge near the confluence of the Rivers Dhoo and Glass in the town of Douglas, Isle of Man, for the opening of the first passenger narrow-gauge (3 ft) railway in 1873.The approach to the Quarterbridge, a mile from Douglas Terminus, was by an 86 ft lattice girder bridge across the River Glass which replaced an earlier structure in 1902.The Douglas to Peel railway line crossed the A5 "New Castletown Road" at the Quarterbridge and followed the River Dhoo and a gradient of 1/105 for a short distance.
