A428

A428 Black Cat - Caxton Gibbet 21 March 2017

Upgrade of the existing A428 to dual two-lane expressway standard between the A1 at Black Cat Roundabout and the A1198 at Caxton Gibbet. This will complete a continuous expressway route between the M1 near Milton Keynes and Cambridge, and contribute to completion of the proposed Oxford-Cambridge expressway.

A428 Bedford western bypass 7 December 2009

Bypassing the road which currently passes through Kempston with a single-carriageway bypass on a new alignment. It will connect the about-to-be-uprgaded A421 at Marsh Leys Junction to the A428 just west of Great Denham (the northernmost mile or so is already open as access to industrial areas).

The road will have 5 at-grade roundabouts (including the northern terminus), 2 pedestrian/cyleway underpasses and a 330m-long viaduct crossing the River Great Ouse.

A northward extension to meet A6 is in planning.
