The Welsh Government’s traffic information service for motorways and trunk roads in Wales

A470 Southbound Swansea Rd Rbt to Abercanaid – Jan to July 2021 (Night-time) – Fibre Network Scheme


Where and Why?

Installations of fibre optic communications ducting will be undertaken on the A470 Southbound from Swansea Road Roundabout to Abercanaid at night-time only. Work commenced 04/01/2021 and will continue until approximately 12/7/2021.

The Welsh Government is delivering a multi-million pound upgrade and extension scheme to its fibre optic communications network. This network provides the backbone for intelligent transport systems to manage the safe operation of the motorway and trunk road in Wales, from CCTV cameras to electronic messages, to traffic counters and emerging digital highway technologies. These systems ensure that our emergency services receive key information when it’s most needed, help to minimise congestion and to deliver safety measures whilst providing data for future road schemes.

The programme will provide resilience for our existing fibre network to help us ensure critical systems and information are always available to our teams and for the safety of road users.

Diversions and Safety Measures

The works are being carried out during night-time hours only to minimise disruption to road users and for the improved safety of the workforce.

The A470 will remain open at all times throughout the works. 

Our contractors will be working 6 nights a week, Sunday to Friday, for the majority of the works, to accelerate the installation as far as possible and minimise the overall impact for the travelling public.

Our contractors will be implementing safe methods of working to adhere to physical distancing measures. Within the constraints, we are taking every opportunity to maximise the number of workers on site and progress the work as efficiently as possible. Multiple teams will be on site to accelerate the programme as far as possible.

Programme of traffic management restrictions

Hard shoulder and Lane 1 closure on the southbound carriageway at night-time only, approx. 20:00 to 06:00, Sunday to Friday.

All traffic management measures will be removed during the daytime to minimise disruption.
