History

Originally a lightly trafficked diamond with the B557, M1 Junction 13, or Ridgmont Interchange has grown in importance in the years since it opened - as it became the main junction for Bedford (with the A5140 extending to the junction) and parts of Milton Keynes (which wasn't there when the junction opened) when the A421 was built. The A507 got diverted to the junction when the area to the south got renumbered, when the A418 was cut back to Leighton Buzzard. The A507 has since been upgraded to a major local route between the A1 and M1, with a recent bypass of Ridgmont changing which side of the junction it met, and the A421 has become a trunk road, serving East-West traffic across the South Midlands between Milton Keynes and Cambridge.

From 2008 to 2010 the junction was upgraded to support the dualled A421 to the north. The end result was a 'triple-diamond' with a new bridge over the M1.
