An upgrade and extension scheme to the road’s fibre optic communications network is planned in South and West Wales. Works are currently taking place on the A477, with works in the future on A40, A48 and M4.

For more information on traffic management see details below.

West Wales

A48 Llandarog Junction

  • Overnight road closure from 20:00-06:00 for 5 nights from June 19th-24th.

A477 Paterchurch (Pembroke Dock) to Nash Fingerpost Junction

  • As necessary, traffic management will be in place for works from 20th June 2022 until end of July. 

  • Works will be suspended on Friday & Saturday nights to minimise disruption. Followed by daytime and night time works for the remainder of the programme.

  • The most disruptive works are programmed to take place overnight to minimise disruption as much as possible.

*Please note that these date are subject to change if weather impacts on the programme of work.

To complete these complex and long-term roadworks, at times we will need to use traffic lights, lane and full closures to control traffic flow during the works. These will be advertised closer to the time.
