The Council will start an important works scheme next week at Allen Street in Mountain Ash, to repair and strengthen a series of river walls and embankments ahead of the winter.
The Nant Ffrwd watercourse runs through the residential area, and six weeks of work from Monday, November 16, will increase resilience to existing infrastructure during storms.
This will include temporary measures to repair scour and undercutting of embankments – along with vegetation clearance, repointing of masonry river walls, and rebuilding a leaning headwall.
The Council has appointed Edwards Diving Services as the contractor to deliver this work, which is being funded via the Council’s Highways and Engineering capital programme (2026/27).
Local traffic management will be used by the contractor, in the form of some carriageway incursion via barriers – but no road closures are anticipated.
Some sections of footway may also need to be closed, but a suitable diversion route will be maintained where possible. Access to premises will be unaffected.
Thanks to the community in advance for your cooperation.
