Drivers in Dacorum warned to avoid overnight road closures on MI and M25
and on Freeview 262 or Freely 565
But motorists will be able to take some solace in the fact that both are only expected to cause slight delays, of less than 10 minutes.
The latest expected works list, with notes from National Highways, shows two closures are due to start over the next two weeks:

> M1, from 10pm July 22 to 5am July 23, slight delays (under 10 minutes): M1 southbound,, junction 10 to junction 9 - lane closures for carriageway - reconstruction/renewal on behalf of National Highways.
National Highways is responsible for maintaining motorways and major A-roads, so closures of smaller roads will not be included in their schedule.
