The White Cart Scherzer Rolling Lift Bridge at Inchinnan just to the West of Glasgow. Built in 1923 by Sir William Arrol and Co, it's one of only two rolling lift bridges left in Scotland.

This type of bridge was first invented by William Scherzer in the 1890s and works by using a rolling action to raise and lower the roadway. This is made easier by the positioning of a large counter weight mounted at one end above the tracks on which it rotates up and down (visible in the top middle of the photo).

Very cool. In this case, I'm not sure what is the purpose of the bridge - why is it necessary to raise and lower the roadway here?
@fionag11 That is a good question. I'm not certain, but it was probably to do with a shipyard or docks upstream of it.
@thisismyglasgow @fionag11 the wiki article says access is still required for the Doosan Babcock factory upstream https://en.m.wikipedia.org/wiki/White_Cart_Bridge
