Drivers in northern Powys can expect delays when travelling at night for the next week as work to carry out “essential resurfacing” on the A470 is carried out.

The work will affect motorists living in and around Machynlleth, as the A470 will be closed north of the town between Cemmaes and Cwm Llinau for the next few days, as well as for part of next week.

Traffic Wales say the road will be closed tonight (Tuesday, March 26) and Wednesday between 7pm and 7am.

“Essential carriageway repair work will be taking place at two locations on the A470 from Cwm Llinau to Cemmaes,” said Traffic Wales.

“Overnight road closures between the hours of 7pm-7am, excluding weekends, from March 25 to March 27.

“The A470 (will also be) closed at Cwm Llinau village and Cemmaes village from April 2-5.

“Arrangements will be put in place to allow customers/workers to access and leave the properties within the closure but this may involve our contractor moving equipment or making working areas safe for members of the public and this may take a short time to implement.

“Please allow extra time for your journeys.”

Diversions will be in place, meaning motorists will face an additional journey time of around 45 minutes and 30 miles.
