Naburn Swing Bridge
From Graces Guide
South of York, north of Selby.
This former railway bridge is now used as a pedestrian/cycleway.
Information from The Railway Magazine, 1907, via the Movable Bridges in the British Isles website:-
There is a live ring 26 bevelled rollers connected to the centre column by horizontal stays. Steam engine-driven water-hydraulic motors drove pinions which engaged with a 32 ft diameter spur wheel fixed to the swing span. As with Goole and Selby bridges the Naburn bridge was locked in position by four remotely-operated locking bolts, and rested on blocks at each end. As the locking bolts were withdrawn the ends of the bridge deck would be raised slightly to give clearance for movement.
