Beginning at junction 13 of the M1, the road heads east past
Ridgmont to
Ampthill. Here it passes between Ampthill and its close neighbour
Flitwick, essentially separating the two. After this it passes
Flitton before crossing the
A6 at a roundabout. Passing
Shefford the road briefly multiplexes with the
A600 before crossing the A6001 and bypassing
Stotfold. Crossing the
A1 at junction 10 of the A1(M), where the motorway becomes a normal A-road, the A507 then heads south east through
Baldock. After bridging over the
A505 (here being the recently opened Baldock north-south bypass) it terminates at a roundabout with the
A10 at Buntingford. ==Ridgmont Bypass==
