Deep but slender curved tapering box girders are almost complete for the central balanced cantilever sections of the new Medway rail crossing in Kent alongside the M2 motorway. The 152.4m concrete main span for the 300km/hour Channel Tunnel Rail Link trains - and shallower back spans - both spring from a 13m deep hammerhead on the river piers. They join push-launched approaches, covering nine spans of 40.5m on the west side and 12 spans visible here on the south (NCE 23 March 2000). French contractor Dumez-GTM brought wide stressing and bridge experience into the equal joint venture with Britain's Miller Civil Engineering Services and Germany's Monierbau with specialist consultant Tony Gee & Partners to advise further on construction engineering issues. Design was by Rail Link Engineering.
