BRIDGING THE TRACKS

This article describes progress made in the construction of a new eastern radial road to bypass Gloucester, which includes the construction by Shand Civil Engineering of a 63m long reinforced concrete bridge which spans the main Bristol to South Wales railway line at a skew of 60 deg. Concrete bored piles were sunk up to 16m deep to support the structure consisting of up to four 100ft 2.7m deep steel beams resting on abutments almost 6m high. The abutments are skewed at 64 deg and 62.5 deg. This is required because of the railway alignment and the need to minimise demolition of adjacent residential properties. A Gottwald AK912 crane was utilized to lift the beams, which were braced together in pairs over the railway track at a radius of 22m. Problems encountered during the work, included finding a method of pouring the concrete for the single span, in-situ reinforced composite concrete deck without displacing the alignment of the skewed beam. This was resolved by placing the concrete in three separate pours ensuring each beam was equally loaded at all times. Two other bridges are briefly described, construction costs for the whole project are 11 million of which 5 million is provided by private developers.
