Forward destinations: London; Reading.
Exit destinations: Oxford; Newbury; A34 [Hollow circle diversion symbol].
Junction number: 13.
The A34 is a major north-south trunk route, linking the docks at Southampton with the Midlands and the North. The roundabout here was horrendously congested until a bypass was built, carrying the A34 around the side of the junction.
