CHANNEL TUNNEL Rail Link (CTRL) engineers have started push launching 45m long concrete deck sections of a 1km viaduct under the QE2 Bridge in east London as part of Contract 310. The viaduct will eventually carry high speed trains under the bridge when the CTRL is completed in 2007. Contractor Morgan-Vinci is push launching deck sections - made up of four prestressed concrete segments - across the top of the viaduct piers. The wedge shaped nose attached to the first segment of the bridge helps to bridge the gap between the piers during each launch. The nose consists of two structural steel girders, each measuring 34.5m long and weighing 75t.
