High Road is a junction connecting the A406 North Circular Road and A1000. It is a 4-ramp parclo but the original plan in the early 1970s was to have 5-ramps with an additional westbound off-slip allowing a freeflow turn to the A1000 south. Another planned feature that didn't materialise was a westbound crawler lane starting at this junction which would have provided four lanes up the ascent to where the A406 passes in a short tunnel beneath the A504.
