 One short section of the dual-carriageway portion of Ringway 4 was constructed in Hoddesdon linking the town to the A10.The overly large junction between the link road and the A10 was built with space available to continue the road westward over the A10 as originally planned.In the central London area only the East Cross Route and part of the West Cross Route of Ringway 1 were constructed together with the elevated Westway which links Paddington to North Kensington.
