The £4.5 million project to resurface the A421 Bedford southern bypass between the A6 at Elstow and the A4280 at Renhold started on the eastbound carriageway on 17 November last year.
As work on the eastbound carriageway is almost complete, work on the westbound carriageway will begin on Monday (26 January). The work will be carried out overnight, between 8pm and 6am on weeknights only.
Drivers should be aware of the temporary road surface during the day, take care travelling through the roadworks and adhere to the speed limit.
The majority of work will be carried out overnight, between 8pm and 6am on weeknights only and is due to be completed by 13 March.
The work is dependent on suitable weather conditions, and dates may be subject to change.
During the overnight closures clearly signed diversion routes will be in place, motorists will leave A421 at the Renhold Junction onto the A4280 Goldington Road, turn left at the traffic lights onto Newnham Avenue. At the roundabout take the second exit onto Longholme Way, to the next roundabout with the A600 (London Road), take the A5140 (Rope Walk), continue along the A6 (Ampthill Road) to the A421.
Live traffic information is available on the Highways Agency website and mobile app, and drivers can also listen to traffic bulletins on local radio for updates.
