Maintenance vehicles have been seen at Glangrwyney Road, connecting Gilwern in Monmouthshire to the A40 near Crickhowell, which was closed in early 2020 after being hit by a number of storms.
Despite being an unclassified road, the route provides quick access for Gilwern residents to neighbouring towns including Abergavenny and Crickhowell.
The road has been closed to vehicles and traffic during the Covid lockdowns, but has remained accessible for pedestrians as a local walking route.
The road itself straddles the counties of Monmouthshire and Powys – and includes crossing the narrow Bailey bridge, over the River Usk.
Monmouthshire County Council have yet to confirm an official date for when the road will be reopened to traffic.
A council spokesperson said: “The rebuilding of Glangrwney Road Gilwern started earlier last week. These works are funded by Welsh Government following the storm damage back in early 2020 and Alun Griffiths is the main contractor for the scheme which is anticipated to be completed during this April.
“At the same time Powys CC are arranging for repairs to the Baily Bridge crossing the River Clydach which when completed will allow this route to be re-opened to full traffic.”
The council confirmed that engineers will be overseeing the work and have assured local residents they will be working closely with contractors to ensure that any disruption is minimised.
MCC Cabinet Member for Highways Cllr Jane Pratt said: “MCC appreciate the disruption that the closure of this road has had on residents and motorists since the January 2020 floods however I am pleased that the works have now started and also that Powys CC will soon be repairing the bridge in order that the road can be fully re-opened and allow people to get back to normal.”
