To enable the replacement of gas mains lying underneath, it will be necessary to close Llantwit Road to vehicles, in both directions, between the junctions of Pen y Dre and Digby Road.
The works, which begin on Monday 15th April, are expected to take around three weeks to complete, and the road closure will be in place for the duration of the works.
The First Cymru X7 bus service will not operate between Tonna Hospital and Llantwit during this time.
However, following negotiations, a replacement shuttle bus service will be provided by Wales and West Utilities for the duration of the closure.
Please click here to see a timetable for the shuttle service.
The shuttle service will start from the junction of Fairyland Rd at Llantwit Cemetery, stopping at all designated bus stops up to Tonna Hospital, with no fares taken for travel on this vehicle.
Passengers who wish to travel onward towards Neath or Glynneath can then catch the First Cymru X7 service, which will be subject to the usual fares.
The shuttle service vehicle will meet all returning passengers on the X7 at Tonna Hospital and transport back down to Llantwit Cemetery.
A timetable has been produced for the shuttle service and will be displayed at all bus stops along the affected area between Llantwit Cemetery and Tonna.
The replacement shuttle service will not be operating on Sundays or Bank Holiday Monday.
