THE construction firm behind the scheme to dual the Heads of the Valleys road will talk about the challenges it faces at Clydach Gorge, near Brynmawr.
Costain began work to dual the 8.1kilometre section of the A465 between Gilwern and Brynmawr in December and is expected to finish in 2018.
Members of the construction team will talk about the innovative techniques being used to minimise the damage to Clydach Gorge at a meeting of Abergavenny Civic Society today.
It is one of the most complex trunk road engineering schemes in the country and includes the construction of 16 major structures, over 11.5kilometres of retaining walls as well as excavation of over 1.2million metres cubed of material.
The design includes a 50mph speed limit, improved junctions and viewpoints of the Gorge, extra laybys at Sale Yard and Clydach Gorge and a safer cycling crossing at Brynmawr and a split-level carriageway.
The gorge is a site of international importance for its geology, habitats and industrial and ancient archaeology.
At the meeting there will also be an opportunity to view a fly-through of the finished scheme and find out more about the timetable for construction.
The meeting takes place at the Methodist Church Hall, Castle Street, Abergavenny at 7.30pm.
All are welcome to attend although there is a charge of £2 for non-members. For details contact abercivsoc@gmail.com
