The construction of the new Dyfi Bridge, located on the A487 near Machynlleth, will improve road safety, strengthen links between communities, provide active travel opportunities and build resilience against flooding. Once completed, the project will also improve transport connectivity to help stimulate further economic development in mid-Wales.
Griffiths have successfully progressed the scheme through the Early Contractor Involvement stage, having been awarded the contract back in 2015.
Works consist of a new viaduct across the floodplain and a new river bridge across the Afon Dyfi, approximately 480m upstream of the existing masonry-arch bridge. The current 19th century bridge is frequently closed due to flooding, an occurrence which is likely to increase with the impact of climate change.
Closures on this section of the A487 can impact on the community’s ability to access key services such as healthcare, education, and public transport in Machynlleth and beyond. The new bridge will provide a safe and reliable route between communities.
The removal of large-scale traffic from the 19th century bridge and provision of a walking and cycle path will improve active travel opportunities increasing the attraction of Machynlleth and surrounding area as a tourist destination.
Works will also include traffic calming and improved drainage on the A493 immediately north of the bridge to protect the existing cottages. A flood bund will also be constructed to protect the Dyfi Eco Park from river flooding.
As well as being a key route between North and South Wales, the A487 is an important link between communities locally. The new bridge will also make public transport more reliable, allowing people to access important services in Machynlleth and further afield. The existing listed 19th century stone bridge will continue to be an important asset for the area as an active travel route in the beautiful Dyfi valley benefiting locals and visitors alike.
This vital infrastructure will also complement the work the Welsh Government is doing to support the mid-Wales Growth Deal to develop new economic opportunities in this important part of Wales.
The Griffiths team at the new Dyfi Bridge site worked with lecturer Steve Bellis and his media students from NPTC Group of Colleges to produce the following podcasts. The project provided hands on work experience for the students who were directly involved in the recording, editing and production of the series.
