The main road between Welshpool and Shrewsbury is set to close overnight for more than a week, with drivers warned of lengthy diversions.
The A458 at Trewern will be shut from 7pm to 6am between Monday, June 15 and Tuesday, June 23 to allow for essential carriageway maintenance.
Motorists could face diversions of up to 40 miles - adding roughly an hour to some journeys.

Traffic travelling east will be diverted along the A458 to Buttington roundabout before joining the A483 towards Oswestry. From there, drivers will need to take the A5 at Mile End roundabout towards Churncote, on the outskirts of Shrewsbury, before rejoining the A458 back towards Trewern.
The same route will apply in reverse for westbound traffic.
Drivers are being advised to plan ahead and allow extra time for their journeys while the overnight closures between Sale Lane and Criggion Lane are in place.
