Roads: Construction

Volume 458: debated on Thursday 29 March 2007

To ask the Secretary of State for Transport what the average cost was of building a mile of (a) motorway, (b) trunk road grade dual carriageway, (c) trunk road grade dual carriageway and (d) an extra lane on a motorway in each of the past 10 years. (124831)

The following table lists the average cost per kilometre in real terms of building motorways, dual carriageway trunk roads and an extra lane to existing motorways, provided by publicly funded major schemes for the last 10 years.

The ranges of cost reflect the different types of projects delivered in each year since 1996. Seven projects were delivered in 1999-2000, two of which included tunnels. One project adding lane capacity was completed in 2001-02 and the majority of its cost was in strengthening an existing bridge.
