https://en.wikipedia.org/wiki/Ashton_Avenue_BridgeThe Ashton Avenue Bridge is a pedestrian, cycling and busway bridge in Bristol, England. Grade II listed, it was constructed as a road-rail bridge as part of the Bristol Harbour Railway. It now carries a Bristol MetroBus guided busway route and National Cycle Network cycle routes.

Designed and opened as the freight-only Wapping Wharf Branch, the bridge was opened on 3 October 1906 by the Lady Mayoress, Mrs A.J.Smith. With both railway and road operations and bridge maintenance undertaken by the GWR▸ , it opened on average ten times a day until February 1934. The controlling railway signals were interlocked with the signal boxes on either side of the river, making it impossible for signals to be cleared unless the bridge span was locked in the closed position.
