Drivers in Wales are set to face a challenging 70-mile diversion as a crucial stretch of the A470 is due to close for three months, beginning this Monday. The closure is necessary due to a collapsed retaining wall on the main route from north to south Wales, affecting a three-mile section between Talerddig and Dolfach. The closure, scheduled from January 20 until April 11, comes after a partial collapse of the retaining wall in October 2023. Following the emergency closure, temporary measures were implemented to stabilize the carriageway, including traffic lights to manage the flow on the westbound lane.
In spite of initial efforts to commence permanent repairs last October, progress was impeded by a tragic rail collision on the Cambrian railway line. The upcoming three-month closure is essential for the permanent fix to be completed, with subsequent works continuing under a two-way traffic light system until April 30. Traffic Wales, responsible for overseeing Wales’ main routes, has affirmed that the complete excavation of the carriageway is imperative for the reconstruction of the wall. The comprehensive works aim to address the structural issues and ensure the road’s future stability.
During the closure period, the A470 will remain inaccessible to all vehicles 24 hours a day, with pedestrian and cyclist access retained. Motorists are advised to follow a diversion route for westbound traffic via Caersws, Newtown (A483), Welshpool, and Mallwyd (A458) before rejoining the A470 at Glantwymyn. Eastbound traffic will be directed along the same diversion in the opposite direction. School transport services will also be impacted by the closure, with provisions being made to minimize disruption during this period.
Acknowledging the inconvenience posed by the closure, a Welsh Government spokesperson highlighted the necessity of the ongoing works to ensure the long-term resilience of the road. The decision to undertake these repairs in winter aims to mitigate travel disruptions at peak times, albeit with expected implications for school transport services. Authorities are liaising with relevant transport bodies to coordinate arrangements during the closure, which coincides with the February half term for schools. Further information on bus services can be accessed for additional clarity on alternative travel options.
Amidst the challenges posed by the extended closure, efforts are being made to prioritize the safety and structural integrity of the A470, a vital transport artery linking regions in Wales. While the anticipated 70-mile diversion presents logistical hurdles for motorists, the completion of these essential repairs is crucial to ensure the road’s longevity and functionality for years to come. As developments unfold over the coming months, ongoing communication and support for affected commuters will be crucial in managing the impact of this significant infrastructure project.
