Works to improve drainage on Maerdy Mountain are set to begin in June heralding the start of a £1.7M investment to repair and improve the road which connects Aberdare with Maerdy.
The A4233 road was damaged by continued wet weather in December 2015, when a landslip occurred at the hairpin bends at the Aberdare end of the road.
In January 2016, more prolonged rain caused the damaged area to grow, leaving a 150-metre stretch of road at risk.
As part of the planned £1.7M investment, which will shortly be considered by Cabinet as part of the 2017/18 Capital Programme, significant engineering works will be undertaken along with the entire mountain road being resurfaced and re-marked, with cats eyes being renewed and repair the dry-stone walls where necessary.
Advanced works inclusive of drainage are expected to start in June with temporary traffic lights remaining in place, as works progress to deal with the landslip. A full road closure will be in place during the school’s summer holidays, which it is hoped will minimise disruption. Advanced signage will soon be in place to alert motorists to the forthcoming investment.
Councillor Andrew Morgan, Leader of Rhondda Cynon Taf Council, who is also responsible for Highways, said:
“In order to fully repair Maerdy Mountain and to future-proof it as far as possible, a significant investment of approximately £1.7m will be required.
“Given how important this road is, it is a priority to get it fully repaired. The landslip was caused by issues with surface and ground water on the mountain during a period of prolonged and heavy rainfall.
“To prevent this happening we aim to install an extensive new drainage system and carry out ground stabilisation works on the mountain side.
“Carrying out the works during the summer holidays allows the necessary time for this, with this period also being the quietest time in terms of cars on the road meaning the least amount of disruption will be caused.
“During the closure, we would also look to take the opportunity to carry out wider works such as extensive resurfacing of the entire mountain road, repairing and rebuilding the stone walls, where necessary and renewing cats eyes.
“Clearly a full road closure on Maerdy Mountain will have an impact on motorists but, as with the works which benefited Rhigos Mountain Road during summer 2016, we will work to minimise disruption and keep residents and motorists fully informed and updated.”
The road has remained open since the landslip, and remains so under traffic lights in the affected area.
Further details and updates will be posted on the Council’s website and social media accounts prior to the work commencing.
