This bridge was built to connect Liverpool and London by shortening the journey which before entailed a change of train at Warrington. This is commemorated by the Arms of London being shown on the Runcorn side of the bridge, the figure of Britannia on the central support and the Arms of Liverpool on the Widnes side.
This view is from the west side of the bridge with Widnes on the opposite bank.
The message reads:-
Alice and I are having a most lovely time here it is a charming place. I hope you are all keeping well.
Kind Regards from Margaret
