Former M1 slip-road at Bunn's Lane

Before the current south end of the M1 was completed, a temporary junction 2 (just north of the current one at Fiveways Corner) ushered traffic onto and off the A1 Watford Way. This slip road enabled southbound traffic to pass under the A1 Watford Way and merge into that road's southbound carriageway. For more details see http://www.sabre-roads.org.uk/wiki/index.php?title=Fiveways_Interchange. For what would have been the driver's view approaching this bridge from the north-west, see Image The slip road follows the line of the abandoned Mill Hill East to Edgware railway: had it not been for changing priorities (due in part to the Second World War, and the Green Belt slowing suburban expansion) this would have formed part of the Northern Line. Under London Transport's Northern Heights Scheme, part of the 1930s New Works Programme, the Northern Line would have taken over various LNER branch lines to form an extensive and complicated network: the line from Highgate to High Barnet and its spur to Mill Hill East is all that remains of this ambitious programme.
