Has any bridge or structure newly built over a UK railway since, say, 1930 ever had to be rebuilt or have its deck raised to provide electrical clearance for subsequent overhead electrification of the railway?
I'm not counting parapets that need to be raised to make it safer for people on the bridge.
I suspect there are no examples. The only bridges I seem to hear about being raised or rebuilt for electrification are ones that date from the 19th century.
However a poster in the Holyhead electrification thread appears to believe that there is a possibility that modern structures such as the 1970s road deck on the Britannia bridge may not have electrical clearance. I think this is an entirely bogus worry and needs to be put to sleep.
Edit: just remembered there were some newish signal gantries in south Wales! I'd better exclude signal gantries.
