It dates from the opening of the London and Birmingham Railway in 1838 and was designed by Robert Stephenson though it has been heavily modified.

The original curved cast-iron girders were replaced with straight ones when the line was quadruple-tracked in 1892 and again in 1946, the second time with reinforced concrete beams.

[1][2] Robert Stephenson, the chief engineer of the London and Birmingham Railway surveyed the route and designed the bridge.

The area is now an industrial zone on the outskirts of Milton Keynes but in the 1830s was largely open land with an inn which served as a stopping point for stagecoaches on the Holyhead Road.
