The east cross route, or London Inner Ring Road System, affects the eastern region of British Railways at Victoria Park and Old Ford. Two under-line bridges are required at Hackney Depot, and three in the Victoria Park area including a 7 span box girder viaduct. A major under-line bridge is required at Old Ford. Site problems required differing forms of structure and different modes of erection. Problems with respect to the demolition of the old railway arch arose at the bridge over Wick Road. Special consideration was given to temperature effects on the Victoria Park viaduct which is on a curve. Old Ford bridge was a particularly difficult problem due to the high density electrified rail traffic and the presence of London transport tunnels and sub-station. This governed the choice of thrust bored abutments under the seven tracks. Superstructure design of all bridges was based on steel box girders, some strong enough to support a single track and others used as a beam group. Plated or concrete decks were used, and some of the parapet girders were clad. Waterproofing was by membrane or epoxy resin. Abutments were generally of reinforced concrete, sometimes on bored piles. /TRRL/
