Chesham Road Interchange is a notoriously tight interchange on the A41 Berkhamsted bypass with the A416.
Layout of original A41(M) design
A junction at this location was originally planned as part of the A41(M)
from 1969-1976. It would have been a roundabout GSJ situated about 200 metres west of the current junction and known as Kingshill Interchange. The alignment of the A416 would have been significantly improved with the dogleg section around Kingswell Way becoming a quiet backroad.
The motorway plan lasted until 1976 when it was decided to replace it with an all-purpose road scheme. The junctions, including this one, were redesigned as lower cost affairs.
