31. Section 2 of the Link will be 24 miles long. From Southfleet, the planned route will head north west to a new station at Ebbsfleet and then under the Thames estuary through a one-mile tunnel. The route will then continue overland to Dagenham, under East London through a 12-mile tunnel via a new station at Stratford and terminate at St. Pancras. The target cost estimate for Section 2 is approximately £2,500 million with a target construction period of 5½ years. Construction is expected to begin in July 2001 and is scheduled to be complete in December 2006.
