Part of the A29 near Dungannon will be closed overnight due to a landslip.
The closure is being put in place between the Tullycullion Road and Thomas Street Roundabout due to a landslip and unstable ground.
Engineers are en-route to assess the ground but due to the earlier slip, as well as the height of the banks and the narrowness of the road, a closure will be put into effect.
Diversions will be through Donaghmore.
The road is likely to remain closed into the morning rush hour so motorists should allow extra time for their journey.
