When this section of the M1 was first built, there was a single overpass carrying an unclassified road at this point. This overpass then became the northern bridge of a standard roundabout interchange when the northern cross section of the M50 was built, which opened in December 1996.
This junction had separate slips for M50 clockwise to M1 north and M50 anti-clockwise; however, in 2010 free-flow right-turn slips were built, creating a directional-T between the M1 and M50, with the old roundabout nestled inside it.
While the new layout has a high capacity, it still suffers from congestion, primarily due to traffic joining the motorway from the roundabout struggling to merge. This unusual layout, effectively a right-hand entrance, has necessitated several signs urging drivers to stay in lane.
The status of the road to the east of here, known as the Northern Cross Route Extension, has caused some confusion. It was designated N32, but the first section of it was a single carriageway road under motorway regulations, making it actually M32. The N32 became the R139 in 2012, and the road had its motorway status removed. Despite this, new signs have gone up calling it the M50!
