PlasdwrHighways updates

In March our contractors, Alun Griffiths, will start removing the current Heol Isaf roundabout and replacing it with a new, four-way signalised junction as part of the infrastructure improvements for Plasdŵr.

While this work is taking place, the two original lanes on Llantrisant Road will be closed and traffic will use the newly constructed lanes on the northern side of the carriageway, where a temporary mini roundabout will be created allowing traffic to travel as normal along Llantrisant Road.

Traffic travelling from Heol Isaf will be able to use the temporary roundabout to turn right onto Llantrisant Road, heading towards Llantrisant. To head left towards Cardiff, traffic from Heol Isaf will use the newly constructed slip road to bypass the roundabout altogether. There will be no left turn at the roundabout for traffic coming from Heol Isaf.

These arrangements are expected to be in place until the new junction is complete in summer 2020. Temporary traffic lights may be required between the hours of 09:30-15:30 to ensure the safety of road users and our contractors, updates will be posted on our Twitter feed @plasdwr.

These timescales are correct at the time of writing.
