Completion in sight for Pwll-y-Pant works (31/10/18)

Residents, motorists and businesses will welcome the news that improvement works at the Pwll-y-Pant roundabout in Caerphilly are nearing completion.

The improvement scheme, which started in October last year, will increase capacity at this key strategic location, as well as reduce congestion and improve journey time reliability.

While initial estimations were that the scheme would be completed within 52 weeks, severe weather and other factors, including altering the programme to re-open two lanes southbound from Llanbradach earlier than originally anticipated in response to calls from members of the public, meant that the programme had to be extended, with a revised projected completion date of before Christmas.

The good news is that, subject to weather and unforeseen events, the programme is now on schedule to be completed by the end of November – in time for the busy pre-Christmas trading period.

Final overnight works are scheduled for Thursday 22nd November (7pm-6am), which will bring works on site to a close. Traffic signals are currently planned to be switched on at the roundabout on Monday 26th November, which will mark the scheme’s completion.

Cllr Sean Morgan, Deputy Leader and Cabinet Member for Infrastructure said, “While these dates are dependent on weather and any unforeseen events, I’m sure this scheduled completion date for the scheme will be welcomed by all concerned. 

“We were obviously very conscious that the programme had extended beyond the originally scheduled 52 weeks, due both to circumstances beyond our control, and changes made to single lane running after listening to concerns from residents and businesses. Local traders are now able to take full advantage of the busy pre-Christmas trading period with no disruption. It’s pleasing that the council and contractor have been able to ensure that, weather permitting at least; the works will draw to a close before the end of November.

“The works have undoubtedly caused disruption for residents, motorists and the business community, and I must thank everyone for their patience while these important works were carried out”.

The new traffic signal system is designed to self-manage and balance flows between all the junctions. There will be a bedding in period over the first few weeks where the system learns where the flow priorities are and readjusts to try and ensure that no one arm has excessive queue lengths.

The scheme, which was funded as a result of developer contributions and Welsh Government grant funding, has seen the following improvements:

  • Partial full time signalisation of the roundabout
  •  Incorporation of a pedestrian crossing on the eastbound lane of the A468
  • New footway linking the existing pedestrian bridge to the footway on Pontygwindy Road
  • Additional filter lane on the A469 in Llanbradach and extension to the existing filter lanes
  • Creation of a dualled lane approach on the eastbound lane of the A468 and duelled exit from the roundabout
  • Creation of an additional filter lane and extension in length to existing filters on Pontygwindy Road
  • Creation of a dualled approach to the A468 Bedwas Arm and exit to the roundabout 
In preparation for final completion, there are a number of further overnight road closures (7pm-6am) required over the coming weeks, in order for final resurfacing and road markings to be carried out. Full details of these closures can be found at
