The Magic Roundabout in Hemel Hempstead, Hertfordshire, England is the familiar name given to a complex road junction also known as the Moor End or Plough roundabout. The name comes from a similar junction in Swindon, whose name is derived from the children’s television series The Magic Roundabout.
It was constructed in 1973 to reduce the congestion at the original standard layout roundabout where seven roads intersected, it was one of the first bi-directional roundabouts to be constructed in the UK. At the junction of each road with the roundabout a mini-roundabout is present and subject to the normal clockwise direction of travel for all traffic. Between these mini-roundabouts however traffic is permitted to travel clockwise or anti-clockwise around the larger roundabout, the expectation being that drivers would choose the shorter route with less stationary traffic.
