225W
§ Mr. SwinglerComparison is difficult because costs vary widely with local circumstances. The current projects for the Brixton extension and the Hendon urban motorway cost respectively about £4,000,000 and about £3,000,000 per mile. But nearer the centre of London motorways in particular will cost much more.
