Mmmm Pilty .. that's interesting, apart from the Viaduct, think all our bridges have been quite small really. Can only think of the following, but perhaps our members may care to add to these:-
Viaduct,
Bull Bridge.
Queens Road Bridge.
Bridge over the canal at Clayton.
Bridge now over the motorway at Clayton.
Rising Bridge
Is there one actually there ?
Hyndburn Bridge. (Oh no !! will it soon be Accrington and District Bridge, but does run over the river).
Gosh, apart from smallish ones that run over the canal and railway,I'm now stumped. !
Sure we can dig up history on all the above . have been threads on some of them if you search. i.e. talked plenty about Bull Bridge.
