What is happening?

As part of the New Dyfi Bridge Improvements Work, construction work is taking place to improve drainage to protect a row of Grade 2 listed properties (Dyfi Cottages) from future flood events. This work needs to take place in early February 2024.

The A493 needs to be closed to all vehicle traffic over a length of about 100 metres along the front of the Dyfi Cottages at Pont ar Ddyfi over a 30-day period for this work to be carried out safely. Pedestrian and cycle access will always be maintained. Parking and bus drop-off and pick-up will be available on both sides of the closure.

The A487 New Dyfi Bridge will be open to traffic during the road closure.

The road closure will come into effect from Saturday 10th February 2024. It is expected that all the required works will be completed within 30 days (weather permitting).

This will affect access between Machynlleth and the Pennal, Aberdyfi, Tywyn area.
