Major roadworks to carry out essential maintenance work on the A487 near Newport in Pembrokeshire for eight weeks are set to begin from January 6 next year.

The works, which are being carried out to ensure the long-term resilience of the road and mitigate against the impacts of climate change, will involve the replacement of a drainage structure which crosses beneath the A487.

It will also safeguard the long-term road links between communities and essential services, such as healthcare providers and schools.

The A487 will be closed in both directions from Parrog St junction to the Market St junction.

A spokesperson for the Welsh Government said: “A full replacement was the only option as the existing structure could not be repaired.

“Working closely with the local authority a local diversion route, controlled with temporary traffic signals, will be put in place. Through traffic including heavy goods vehicles, will follow a longer, approximately 35-mile diversion route.

“This work is essential in order to ensure the road can remain open in the years to come. We understand this will cause disruption in the short term while the work is under way, and we thank drivers for their patience. It is vital this work is carried out at this time for the future resilience of the road.

“Consultations have taken place to identify the least disruptive time of year to carry out the works.

“Direct support from Business Wales is available for businesses facing uncertainties due to the road closures and we will be working with local businesses to assist with accessing this support.”

Local businesses will remain open for the duration of the works.

Preliminary works to re-direct the telecommunications equipment before the main works begin have already taken place on Sundays throughout October and November.
