The works noted will be undertaken between Monday 26th October 2026 and Wednesday 31st March 2027 at this location. This could result in a higher than usual level of noise and/or traffic disruption at intervals.
A full closure of the A40 will be required on 26th October and will be implemented between 20:00 – 06:00 (when traffic flows are lower).
A single lane closure will be in effect from 27th October 2026 to 31st March 2027, on the stretch of road between Pyscodlyn Farm and the County Boundary at Glangrwyney. This will be managed with the use of two-way traffic lights.
