We are planning a new section of the A487 north of Machynlleth, including a new bridge across the River Dyfi.

Summary

Project status: planned
Order Exhibition date: Tuesday October 3 (17.00 - 20.00) and Wednesday October 4 (10.00 – 20.00)
End of objection period : October 18 2017
Start date for construction: autumn 2018
Road open: summer 2020
Early contractor involvement contract: Alun Griffiths (Contracting) Ltd

Why we are doing it

The Pont-ar-Ddyfi was not designed to carry the current volume of traffic, and so is a pinch point on the A487. The road is also often closed due to frequent flooding causing traffic to take a diversion of up to 30 miles.

The existing bridge is Grade II* listed and a Scheduled Ancient Monument so we are restricted in what alterations we can make.

Our objectives are to:

  • improve the reliability of crossing the River Dyfi
  • improve access to key services including employment opportunities, healthcare and education
  • ensure Machynlleth remains a vibrant and sustainable local centre
  • preserve the long-term integrity of Pont-ar-Ddyfi
  • reduce the number and severity of collisions on the A487
  • ensure the flood risk is not increased
  • increase safe and reliable, walking and cycling opportunities.

We will minimize the impact of these improvements on the landscape, biodiversity, water resources and heritage of the area.

Current progress

We have undertaken studies which have considered both improvements to the existing road and bridge, and also the option of constructing a new road and bridge off the line of the existing road.

If the Pont-ar-Ddyfi were to remain part of the A487 we would need to strengthen and widen the bridge, which would significantly change the historic bridge and cause major disruptions during the works.

We found from the studies that a new road crossing the river upstream of the existing bridge was a better solution.

We have recently published draft orders for this project.

The plan

We plan to build a new single carriageway road joining the existing A487 south east of Pont-ar-Ddyfi. The new road would cross the River Dyfi approximately 480m upstream of the existing bridge. This new stretch of road would become the A487, with the existing road north of the bridge becoming the A493. The A493 and the existing A487 south of the Pont-ar-Ddyfi would no longer be a Welsh Government maintained trunk road and so would be maintained by local authorities.

Timetable

Publication of draft orders and environmental statement: summer 2017
Orders exhibition: summer 2017
Public local inquiry (if required): spring 2018
Road open: summer 2020

If the Public Local Inquiry concludes that the scheme should be given approval to proceed then construction could start in autumn 2018.

Next steps

We will hold a draft orders exhibition on the 3 and 4 of October 2017. The objection period is currently planned to end on 18 of October 2017.

The draft orders set out the land we require to construct the new road and explain the resultant environmental impact. Now that the draft orders have been published  the public and other stakeholders will be able to express their views. These comments will help better inform us on how we should progress this scheme and whether we will be required to organise a public local inquiry.
