Britain's first roundabout...
... or perhaps more accurately, the first ‘gyratory traffic flow system’ built in the UK.
The intersection of Broadway, Spring Road and Sollershott East and West.
Built about 1909.
The roundabout was originally designed as a refuge for pedestrians to help them cross a three-road intersection. Twenty years later, a decision was taken to direct all traffic to move in the same direction and a roundabout, as we know it today, was created.
