Question to the Department for Transport:

To ask His Majesty's Government, further to the Written Answer by Lord Hendy of Richmond Hill on 27 October (HL11341), what credit was claimed for the potential reduction in congestion and journey times arising from the widening scheme on the south-western stretches of the M25; for what period these claims were made; and what has been the actual experience.

The widening of the south-western stretches of the M25 took place over twenty years ago, with the most recent scheme (M25 J12-15) completed in 2005. Any information available on schemes completed a long time ago will be held in the National Archives.
