William Kelly Wallace
date  rebuilt 1947
era  Modern  |  category  Railway Viaduct  |  reference  SD572052
ICE reference number  HEW 1048
Wallace, chief engineer of the London, Midland & Scottish Railway, designed the rebuilding of this four-span railway viaduct. It was the first bridge in the country to carry live railway loads on pre-stressed precast concrete beams.
The original bridge carried the then Liverpool & Bury Railway and was constructed in 1847. It was strengthened three times before its rebuilding in 1947.
The concrete beams are 2ft 8in deep and six are used per track, plus one for each parapet. Pre-stressed precast beams had been prepared first in 1938-39 for emergency wartime use for replacing damaged road bridges over railways.
Contractor (1947): Leonard Fairclough Ltd
