The bridge is heavily skewed[2]—the railway continues in a straight line while the road passes underneath—giving it elongated wing walls, particularly on its west side.

[2] It was widened in the 1880s by the L&BR's successor, the London and North Western Railway, when the line was quadruple-tracked.

[3] The bridge was designated a Grade II listed building in 2001 in recognition of its historical and architectural significance.

Listed building status provides legal protection from demolition or unsympathetic alteration.

[1] Wolverton was home to L&BR's engineering works and multiple structures associated with the L&BR survive, including the original bridge over the canal (which now only serves the works), the Blue Bridge, and Wolverton Viaduct to the north.
