Junctions
Data from driver location signs provide carriageway identifier information. The numbers on the signs are kilometres from a point near the River Thames, east of London, when travelling clockwise on the motorway. The table below gives details of each junction, including the roads interchanged and the destinations that are signed from the motorway. Figures in kilometres are from the driver location signs; figures in miles are derived from them.
