Blue Bridge was built in the 1830s to span the London and Birmingham Railway (L&BR) (now the West Coast Main Line near Wolverton Works in Buckinghamshire, southern England.
[1] When a modern bridge (Millers Way) was built alongside, it continued in use for a time as a shared path but, after being declared unsafe, is no no longer open for use.
It has three elliptical arches in blue engineering brick which stand on piers of local coursed, squared limestone, faced with rock.
[1][2] The original bridge was designed by Robert Stephenson, the chief engineer to the London and Birmingham Railway, and was opened at roughly the same time as the line in 1838.
All other overbridges on this section of line were rebuilt in the 1950s when overhead electrification equipment was installed, making the Blue Bridge a possibly unique survivor.
