Roads Mr. Paterson To ask the Secretary of State for Transport what the average maintenance expenditure per mile of road on (a) A roads and (b) B roads was in each region in the last period for which figures are available. Dr. Ladyman The relevant data are not currently compiled to show information for B roads separately from other non-principal roads. The available data for local roads in England are shown in the following table: -------------------------- |£ per km | -------------------------- |Region |Principal roads|Non-principal roads| -------------------------- |East of England |24,492|5,967| -------------------------- |East Midlands |16,640|5,541| -------------------------- |North East |18,643|6,778| -------------------------- |North West |24,585|8,110| -------------------------- |South East |19,081|6,050| -------------------------- |South West |17,738|4,243| -------------------------- |West Midlands |20,447|5,798| -------------------------- |Yorkshire and Humberside|18,355|5,346| -------------------------- |London |157,313|16,086| -------------------------- |England |28,473|6,366| -------------------------- Equivalent figures for Highways Agency maintained A roads are not readily available. Table 7.13 in Transport Statistics Great Britain, a copy of which is available in the Library of the House, provides estimates of Highways Agency expenditure on roads in Government Office Regions; however, this does not separately identify expenditure on maintenance from that on new construction, road improvements and winter servicing. Mr. Carmichael To ask the Secretary of State for Transport what the average 24-hour traffic volume was at the (a) J3-J4E, (b) J4A-J5, (c) J9-J10, (d) J10-J10A, (e) J10A-J11, (f) J12-J13, (g) J6-J7 and (h) J9-J10 automatic traffic counters on the M6 on (i) Mondays to Fridays, (ii) Saturdays and (iii) Sundays in each month since April 2005. Dr. Ladyman The traffic flows for the period from April 2005 to September 2006 are provided in a table, which has been placed in the Library of the House. Mr. Carmichael To ask the Secretary of State for Transport what the average 24-hour traffic volume was at the (a) J6-J7 and (b) J9-J10 automatic traffic counters on the M42 on (i) Mondays to Fridays, (ii) Saturdays and (iii) Sundays in each month since January 2006. Dr. Ladyman The traffic flows for the period January to September 2006 are provided in a table, which has been placed in the Library of the House. Mr. Carmichael To ask the Secretary of State for Transport what estimate he has made of (a) the net change in UK carbon dioxide emissions resulting from the road schemes approved through the targeted programme of improvements and local transport plans since 1998 and (b) the effect on annual carbon dioxide emissions of each road scheme approved by Ministers through the local transport plans since 1997. Dr. Ladyman I refer the hon. Gentleman to the answer of 6 November 2006, Official Report, columns 684-5W, to the hon. Member for Epsom and Ewell (Chris Grayling). I also refer to the answer that I gave on 8 May 2006, Official Report, column 23W. Mr. Carmichael To ask the Secretary of State for Transport what the 10 most congested (a) motorways and (b) non-motorway roads were in the last year for which figures are available. Dr. Ladyman The Department for Transport published its PSA target relating to a reliability measure of congestion for England in February 2006. This related to delays on the worst 10 per cent. of journeys for 103 recognisable routes that make up the strategic road network, and applied to the time period from 1 August 2004 to 31 July 2005 (the baseline year). Details, including data for individual routes, can be found at: http://www.dft.qov.uk/stellent/qroups/dft_transstats/documents/page/dft_transstats_611154.hcsp Mr. Carmichael To ask the Secretary of State for Transport what total length of roads has been detrunked in each (a) county council and (b) unitary authority area since 1997. Dr. Ladyman The following tables list total route lengths transferred to local highway authorities in England under the White Paper “New Deal for Trunk Roads in England”. ------------------------------------ |Local highway authority|Total (km)| ------------------------------------ |Bedfordshire |54 | ------------------------------------ |Buckinghamshire |29.56 | ------------------------------------ |Cambridgeshire |79 | ------------------------------------ |Cheshire |187.8 | ------------------------------------ |Cornwall |76 | ------------------------------------ |Cumbria |133.57 | ------------------------------------ |Derbyshire |137.3 | ------------------------------------ |Devon |95 | ------------------------------------ |Durham |36 | ------------------------------------ |Gloucestershire |84 | ------------------------------------ |Hampshire |23 | ------------------------------------ |Hertfordshire |102.452 | ------------------------------------ |Kent |30 | ------------------------------------ |Lancashire |94.15 | ------------------------------------ |Leicestershire |65 | ------------------------------------ |Lincolnshire |251.9 | ------------------------------------ |Norfolk |49.1 | ------------------------------------ |North Yorkshire |69.86 | ------------------------------------ |Northamptonshire |47.8 | ------------------------------------ |Northumberland |63.6 | ------------------------------------ |Nottinghamshire |90.2 | ------------------------------------ |Oxfordshire |97.8 | ------------------------------------ |Shropshire |80.9 | ------------------------------------ |Staffordshire |51.61 | ------------------------------------ |Suffolk |60 | ------------------------------------ |Warwickshire |37.5 | ------------------------------------ |Grand total |2,127.10 | ------------------------------------ ------------------------------------ |Local highway authority|Total (km)| ------------------------------------ |Bradford City |15 | ------------------------------------ |Calderdale |20.26 | ------------------------------------ |Doncaster |21 | ------------------------------------ |Knowsley |6 | ------------------------------------ |Leeds City |46.4 | ------------------------------------ |Liverpool City |0.3 | ------------------------------------ |Rotherham |9.5 | ------------------------------------ |Salford City |4.5 | ------------------------------------ |Sefton |23.86 | ------------------------------------ |St Helens |19.83 | ------------------------------------ |Stockport |7.4 | ------------------------------------ |Tameside |1 | ------------------------------------ |Wigan |13.2 | ------------------------------------ |Wirral |10 | ------------------------------------ |Grand total |198.25 | ------------------------------------ ------------------------------------- |Local highway authority |Total (km)| ------------------------------------- |City of York |23 | ------------------------------------- |East Riding of Yorkshire|50.5 | ------------------------------------- |North East Lincolnshire |1 | ------------------------------------- |North Lincolnshire |9 | ------------------------------------- |Nottingham City |7 | ------------------------------------- |Peterborough City |5 | ------------------------------------- |Rutland |19.5 | ------------------------------------- |Slough |4 | ------------------------------------- |Swindon |3.7 | ------------------------------------- |Telford & Wrekin |13.4 | ------------------------------------- |Warrington |1.5 | ------------------------------------- |West Berkshire |10.8 | ------------------------------------- |Grand total |148.4 | ------------------------------------- Additionally, 275.98 kms of cross boundary routes has been de-trunked under the programme. It is not possible to separate this figure by local highway authority as the associated statutory instruments do not provide detail on how these routes were divided. Mr. Carmichael To ask the Secretary of State for Transport how many vehicles on average used the M6 toll motorway in each month since January (a) in total and (b) on (i) workdays and (ii) weekends and public holidays. Dr. Ladyman Traffic figures for the M6 Toll are published on the M6 Toll operator's website: www.m6toll.co.uk The daily averages of vehicles using the M6 Toll during the period from January to September 2006 in total, on work days and on weekends and public holidays have been placed in the Library of the House.
