6. Includes motorway slip roads
1. Motorway road lengths are derived from GIS from 2000 onwards - see commentary for more details.
2. Road lengths are physical length rather than carriageway length e.g. 10km of dual carriageway counts as 10km, not 20km.
3. There is no change in the trunk road lengths for 2005 over 2004. This is due to new roads being opened after 1st April i.e. too late to be included.
4.Trunk road lengths for these roads have now been derived more accurately using a GIS system from 2006.
5. From 2008 onwards single and dual carriageways figures are estimated.
