Bat survey edges Rhondda Tunnel closer to realisation

A bat survey has taken place on what could become Wales’ longest walking and cycling tunnel and, according to one estimate, yield economic benefits of £14.3m over 30 years.

The bat survey on the Rhondda Tunnel is the latest step forward in a project to link two valleys with a cycling and walking route, after the project was given the green light to estimate final  construction costs and apply for planning permission last month

Last year the Rhondda Tunnel Society earned the backing of Welsh Assembly Members in its bid to reopen Wales’ longest tunnel for cyclists and walkers, which runs from Blaencwm in the Rhondda Valley to Blaengwynfi in the Afan Valley. The former railway tunnel – the longest in Wales – was closed as part of the Beeching cuts in 1968, but it is hoped it could become a tourist attraction if reopened.

The results of last month's bat survey will reveal the extent of the wildlife inside, and whether a second survey is needed. Rhondda Tunnel Society chairman Stephen Mackey told Wales Online he’s confident of a positive outcome.  

“We eagerly await the results and are very confident all is fine.”

Stephen added: “If bats are found to inhabit the tunnel, then a bat friendly habitat roosting place would have to be built in when the tunnel opens, for the bats to use alongside us humans.”

Following the survey photographs were released of the tunnel’s interior.

A report by Sustrans warned similar projects have proved "a sapping test of resolve", akin to a "steeplechase through a minefield" due to the potential for unforeseen issues cropping up, but said conditions were favourable and the project could yield economic benefits of up to £14.3m over the next 30 years.

The report said: “Our assessment has been estimated that an economic impact of between £7,327,496 and £14,363,652 could be expected over the next 30 years.

“The project would create or support 12.7 jobs for every £1m of investment in sustainable transport infrastructure made.

“To take the project to the next major stage of its development would require an investment of approximately £300,000.

“This is the funding required to obtain planning permission and to calculate a robust final construction cost. This report has not been able to estimate this final cost because of too many unknowns associated with the condition of the tunnel.”
