Cheriton Interchange provides access to the M20, A20 and B2064 at Cheriton, Kent. The two bridges carry the interchange roundabout over the M20 motorway adjacent to the rail terminal for the Eurotunnel.
Cheriton Interchange Bridges have two span reinforced concrete bridge decks on reinforced concrete cantilever abutments and centre piers. The bridges were designed for HA and 37.5 units of HB loading to BE 5/73 & BS 153:Part 3A:1972. Reinforced concrete was designed in accordance with CP114 and BE 1/73(1st Revision).
Deisgned in 1976

In 1978 the Central Electricity Generating Board requested that the west bridge be strengthened to carry a 450 tonne vehicle on 14 axles or 425 tonne vehicle on 12 axles. This modification was incorporated into the design before the Bridge was built.
