The town contains a large roundabout called Magic Roundabout. This is achieved by surrounding the main island with one smaller roundabout per entry/exit street. The concept of tramway crossing roundabout is selected by some cities. This is situated beside the roundabout for Aberdeen Airport on the A96. The tram stops are in the center of the roundabout. Boom barriers protect the railway from oncoming traffic at the appropriate points in the roundabout. Traffic is controlled by two-colour traffic lights inside the roundabout. Both stations are situated on the north-eastern edge of the roundabout. It forms the north side of the gyratory system also known as Hammersmith Roundabout. Suppose the roundabout spins anticlockwise when viewed from above. Tata Steel Tubes Europe is in Corby, along the A427 near the A43 roundabout.
