Updated: Half term closure of Miskin Road and Mountain Ash Cross Valley Link

This section of Miskin Road was made a two-way road as part of the Cross Valley Link scheme

*UPDATED - 27/10/21: Unfortunately, the Council’s contractor hasn’t been able to complete its programme on schedule. The closure will therefore be extended to Thursday, October 28, under the same arrangements as below


The Council is advising residents and road users of remedial work required at Miskin Road in Mountain Ash, which also requires day-time closures of the Cross Valley Link – scheduled for the school half term to minimise disruption.

The Mountain Ash Cross Valley Link opened to motorists, cyclists and pedestrians in October 2020, as the Council delivered the multi-million pound new link road which has vastly improved traffic flow within local communities.

A series of follow-up works are now required in order to correct defects at Miskin Road – including resurfacing sections of the carriageway, inspecting chamber and kerb repairs, and bridge deck drainage repairs. This will be carried out by the Council’s contractor for the overall scheme, Walters-Sisk – at no cost to the Council.

As a result, the new two-way section of Miskin Road and the Cross Valley Link will close from Monday, October 25, (9am to 4.30pm), for around three days. The necessary closure is scheduled for the school half term period, and outside of peak hours, to minimise disruption.

An alternative route for motorists, from Miskin Road, will be via Oxford Street, Commercial Street, High Street, Llanwonno Road, Hawthorn Terrace, Glamorgan Street, Abercynon Road and Penrhiwceiber Road.

From the opposite side of the closure, proceed via Penrhiwceiber Road, Abercynon Road, Glamorgan Street, Hawthorn Terrace, Llanwonno Road, High Street. Commercial Street, Oxford Street, Henry Street and Miskin Road.

For motorists travelling between Miskin Road and the A4059, an alternative route will be via New Road (A4059), Frwd Crescent, Mountain Ash Town Centre Bridge, Commercial Street, High Street, Llanwonno Road, Hawthorn Terrace, Glamorgan Street, Abercynon Road and Penrhiwceiber Road.

Access to all residential properties will be maintained throughout the works, while pedestrian access across the Cross Valley Link Road will also remain available at all times. 


*The Council has now finalised alternative bus arrangements, which will run from 9am to 4.30pm on the three days of the closure (Monday to Wednesday, October 25-27).

During the closure, Keepings Coaches, the new operator of Service 3 (Cefnpennar to Penrhiwceiber) will only be able to run between Cefnpennar and Mountain Ash. Stagecoach Services 60/61 (Aberdare to Pontypridd) will divert via Perthcelyn, with Service 95 (Aberdare to Perthcelyn) will only operate as far as Mountain Ash Railway Station and not serve Perthcelyn.

A free shuttle bus service for passengers wishing to travel between Mountain Ash Railway Station, Miskin, Penrhiwceiber (main road stops) and Perthcelyn Terminus, will be operated by Davies Coaches. It will depart from the railway station at 9am, 9.28am, 9.58am and then every 30 minutes until 4.28pm. In the opposite direction, it will depart from Perthcelyn Terminus at 9.15am, 9.45am, 10.15am and then every 30 minutes until 4.15pm.

The shuttle bus will meet Services 60/61 at Perthcelyn Terminus and services 3 and 95 at Mountain Ash Railway Station for onward travel.

All bus services should follow their normal routes before and after the closure times on the above dates.


The contractor will have site offices located near to its former compound area on the Cwm Cynon Industrial Estate, which it used throughout the duration of the main construction works. Residents and businesses are welcome to contact (07741 265919) or (07977 197150) with any queries.

Walters-Sisk will also be writing to residents and businesses shortly, to outline further details about the upcoming scheme. Thanks to the community in advance for your cooperation as this necessary remedial work is completed.
