Kings Worthy Interchange

Kings Worthy Interchange is at the northern end of the original Winchester Bypass. Originally a crossroads, the A34 was added to the junction in 1969.

The original layout of the junction

As the A33 has been bypassed by the M3, the A34 has become the mainline, effectively creating a rare right exit. However, due to the rarity of such a layout, a lane drop exists. A bottleneck is created by this lane drop briefly putting A34 traffic into just one lane.
