Completed in 1909, the lattice girder Queen Alexandra bridge was originally built as a double decker with a railway above the road. Declining coal traffic lead to the railway line falling out of use not long after the bridge was opened.
The Monkwearmouth road bridge, completed 20 years later in 1929, is a rather more elegant structure. In fact, if you plot the bending moment diagram for a uniformly loaded beam, this is the shape that you get!
