The E24 runs from Birmingham to Ipswich, providing a link between the Midlands and the Haven Ports of Harwich and Felixstowe. It uses the M6 to Catthorpe, where it meets the M1/E13, and then the A14 to Ipswich, running concurrent with the E15 from Spittals Interchange near Huntingdon and Girton near Cambridge.
From the inauguration of the new system in 1983, to the renumbering program of 1985, this route was numbered E28. The E24 ran from Hamburg to Berlin during these years. The numbers were then swapped.
Before the opening of the A14 link between the M1 and the A1, the route went via St Neots, where the A45 heading west into East Anglia could be picked up. The route via Northampton, the A428 and Bedford was the trunk road, and would have been considered to be the route between Birmingham and St Neots.
