As work on the dualling of the A465 from Gilwern to Brynmawr progresses, the next stage requires a major change in the road layout at the Glanbaiden Roundabout.

Over the past few months the western side of the roundabout has been closed to traffic to allow Costain’s engineers to construct the western bridge abutments.

The company now intends to open the western side of the roundabout and close the eastern side for the construction of the eastern bridge abutments.

As a result, traffic from Gilwern wishing to travel westbound (towards Brymawr) on the A465 will be officially routed to the Hardwick roundabout to return via the A465 to Glanbaiden.

Similarly traffic wishing to enter Govilon from the westbound exit of the roundabout will be diverted back onto the A465 to the Hardwick roundabout and then return.

The changes were due to be made either on Sunday December 6 or on Monday December 7 and the new arrangements will be well signposted. The arrangements will remain in place until the week commencing December 21 when the full roundabout will be reopened for a two-week period during the Christmas and New Year holidays.

The eastern side closure will then be reinstated in the week commencing January 4.
