A340 Thornycroft Roundabout improvements 30 September 2016
As part of a range of improvements to junctions around Basingstoke, Hampshire County Council propose to improve the A340-A3010-B3400 Thornycroft Roundabout to relieve the congestion it frequently suffers.
Similar to the plans for other nearby junctions, widening is proposed for all approaches to provide additional lanes, more lanes will be provided on the gyratory itself, and entry points will be controlled by traffic lights. The north west quadrant will have a segregated lane leading onto Churchill Way West. There will also be improvements for pedestrian crossings.
