HC Deb 13 November 1989 vol 160 c73W
Mr. Cartwright

To ask the Secretary of State for Transport what are the current estimated costs of extending the Jubilee line to(a) Woolwich and (b) Thamesmead.

Mr. Portillo

It has been estimated that it would cost about £285 million in today's prices to add a branch to Woolwich to the proposed extension of the Jubilee line to Canary Wharf and Stratford. Extending such a branch beyond Woolwich to Thamesmead would cost about a further £135 million in today's prices.
