Where & Why?

Due to the poor condition of the carriageway along this section of the A465, safety critical resurfacing works are urgently required to repair the deteriorated carriageway. This work will be taking place along the section of the A465 between Tredegar Interchange and Dowlais Top Roundabout.

Diversions & Safety Measures

Works are programmed to commence on Sunday 5 February 2017 and are expected to be complete by Friday 28 April 2017.

Throughout the scheme duration the road will remain open as normal during the day, with night time closures in place between the hours of 8pm and 6am Sunday to Thursday. Diversion routes will be clearly signed when closures are in place.

The works are being undertaken during this period to ensure that any disruption to road users is kept to a minimum.
