aberdare bypass

The Council is carrying out ground investigations on land east of Penywaun and Hirwaun for the future A465 Cynon Gateway North – with these works set to be completed during the New Year. 

The ground investigations began on Monday, December 2, taking place along the proposed alignment of the future bypass – with Quantum Geotechnical Ltd appointed to undertake the work.

The contractor may require traffic management on the A4059 near Penywaun to carry out elements of the scheme. The Council will give advanced warning of any significant disruption. 

The Council has previously committed to delivering the A465 Cynon Gateway North in the future – which is a bypass extending the A4059 and creating a new link to the A465 Heads of the Valleys Road. 

In October 2018, Cabinet supported Welsh Government’s plan to dual 17.7km of the A465, from Hirwaun to Dowlais Top, with work likely to start on site during 2020/21. This scheme will include an additional junction on the A465 at Croesbychan – and this junction will facilitate the Council’s bypass extension. 

This scheme has huge potential for economic benefits to the Cynon Valley, by improving accessibility and connectivity, and providing infrastructure to promote economic activity within the Cynon Valley. It will also include measures to accommodate and promote Active Travel. 

During July 2019, the Council undertook traffic monitoring along the A4059 and the Heads of the Valley Road (A465), to capture traffic patterns. 

The upcoming ground investigations will see trial trenches/pits and bore holes undertaken – to gather geotechnical data for the next phase of the scheme’s design. The investigations are due for completion during February 2020. 

Councillor Andrew Morgan, Leader of Rhondda Cynon Taf Council and Cabinet Member with responsibility for Highways, said: “Significant ground investigations are underway as an important part of the design phase of the future A465 Cynon Gateway North, which will significantly reduce traffic congestion in the north of the Cynon Valley and has the potential for huge economic benefits in the region. 

“This important project has the support of Welsh Government, alongside its own A465 dualling from Hirwaun to Dowlais Top – which will provide the key link for the bypass extension at Croesbychan. The Council has previously announced its full commitment to making this project a reality, and Cabinet Members agreed to allocate £1m to the scheme in October 2018. 

“The Council will work closely with its contractor to complete the upcoming work as efficiently as possible. Some traffic management may be required on the A4059 throughout the scheme, and we will work to ensure any disruption is kept to a minimum. I’d like to thank residents and road users in advance for their cooperation.”
