Work to repair areas of surfacing on the bridge in both directions on the A421 in Bedfordshire is due to begin next week.
The Highways England renovations to the A421 Bedford bypass eastbound and westbound bridge, will begin on Wednesday 3 February and will take 4 nights to complete. The work is due to finish on Tuesday 9 February.
Work to the bridge will be carried out overnight from 8pm and 6am and the road will be closed between the junction with A4280 St Neots Road to the A6.
The closure is required to allow the resurfacing repair work and bridge inspections to take place safely on top of the bridge.
Anna Graham, Project Manager at Highways England, said:
We’ll be carrying out the repairs to the bridge overnight when it’s generally less busy – minimising disruption to drivers. This work is necessary to ensure smoother and safer journeys.
I’d urge motorists to plan ahead and allow extra time for their journeys while the work takes place.
There will be clearly signed diversion route, but drivers will be diverted via the A6 Ampthill Road, Rope Walk, Longholme Way, Newnham Avenue and A4280 Goldington Road to re-join the A421 at Renhold interchange.
The work is dependent on suitable weather conditions, and dates may be subject to change.
