Construction of the steep climb up from the Thames Tunnel through Ebbsfleet to the junction with CTRL Section One at Southfleet is principally about highway works and a strategic station.
The civils works in this area have been packaged into two separate contracts, C340 for the new Ebbsfleet Station and C342 for the civils works, the A2 junction and Ebbsfleet Station approach roads, and the railway works associated with the tie in to the existing North Kent Line.
Most of the 3.5km length of the railway in Contract 342 is across former chalk workings for the long established cement industry.
At the site of Ebbsfleet Station the foundations and columns for the station, together with the flying junction connection to the North Kent Line, are now included in the C342 package.
Further up the hill, CTRL skews beneath the A2 trunk road in a combination of cut and cover tunnels, jacked tunnel and retained cut.
Major service diversions are required. Early enabling works including a cable tunnel under the line of CTRL and A2 connecting in to a local substation were completed in 1997.
At the moment, getting Contract 342 to the point that a contract can be awarded early in January 2002 is high up on Rail Link Engineering's 'critical' list. Contract 340 is to be tendered in May 2002.
