Bedford's motorists will have nine road closures to avoid nearby on the National Highways network this week.

And one of them is expected to cause major delays – with drivers facing a holdup of at least 30 minutes. Another two will cause moderate delays of between 10 minutes and half an hour.

The latest expected works list, with notes from National Highways, shows that four closures already in place are expected to carry on this week:

• A421, from 8pm to 6am until tomorrow (Tuesday), slight delays (under 10 minutes): A421 both directions, Elstow to Cardington – exit slip road closures, entry slip road closures, lane closures and diversion routes due to drainage works on behalf of National Highways

On average, you could be delayed by about 30 minutes
