Handy Cross roundabout

Handy Cross roundabout is a major road interchange at Handy Cross, High Wycombe, Buckinghamshire; the junction for High Wycombe, the M40 motorway and the A404 dual-carriageway. It is the terminus of the A4010 which runs to Aylesbury.

The first section of the M40 to open was the section between junctions 4 and 5 in 1967, construction starting in 1964. The 1967 finished roundabout allowed interchange between the M40, the A404 to Marlow, the A404 into central High Wycombe and a minor residential street. The first alteration came in 1972 with the construction of the Marlow bypass . Further urbanisation to the west of the roundabout led to another exit for the roundabout to Cressex and on through Wycombe to the A40-the new road was given the A4010 road number.
In 2006, the Highways Agency constructed several improvements to the roundabout including a cut-through, bypassing the three northern exits and a new slip road from the A404 to the M40 westbound.
