The Green Man Roundabout is an important junction in East London. It is on the A12 just north of Leytonstone town centre. The A12 underpass is 174m long and was completed at a cost of £7.04m


The A406 ending at the Green Man (bottom right), late 1920s

Originally the junction was a 5-way junction, with three major arms and two minor ones. On classification two of the major arms were the A11, and the other the A115, with the minor arms B160 and B162. By the end of the 1920s, the A115 had been absorbed into the A106 Eastern Avenue, and the B160 had become part of the A406 North Circular Road.

1962 plan for the junction

After WW2, the junction was a roundabout. By the 1950s there were plans to substantially upgrade the A11-A12 (nee A106) corridor in the area. A draft order was made in 1958 for a limited access dual carriageway but nothing ever came of it. Similar proposals continued through the 1960s. A plan from 1962 shows a combined trumpet/roundabout interchange.

By the end of the 1960s the M11 was planned to run parallel to the A11. This would have had some changes to the proposals and the trumpet part of the planned junction is no longer shown. The M11 scheme persisted throughout the first few years of the 1970s but like the earlier plans this also remained unbuilt.

By the 1980s continuing congestion in the area resulted in further studies being undertaken and approval was given in the early 1990s to build a road very similar to the original 1950s plans but with a simplified Green Man Interchange. The A12 passes beneath the roundabout in a tunnel rather than on a flyover. It opened in the late 1990s, some 40 years after first planned.

With the opening of the underpass and realignment of the roundabout, access to the A114 itself was also changed, with its arm directly linking to the postwar roundabout closed; instead being accessed from the A106 arm only.
