|Location Map ( geo)|
The junction is squeezed into the space left it by 1930s plans for an arterial parkway orbital route for London, with the area Northwest and East of the junction developed with residential properties before the motorway began construction. The compact nature of the junction means that the A404 often backs up because of this, although, post-M25 widening works to alter the signal timings has reduced the issue. The clockwise sliproad is single-carriageway.
