The Welsh Assembly Government took the decision to close a short section of the A5, between Ty Nant and Dinmael, in the interests of public safety. The Assembly Government are continuing to work with local authorities, business and tourist representatives to minimise any adverse effects.
I understand that remedial works could take around six months to complete, depending on site conditions. However, the meantime, urgent steps have been taken to provide an alternative route to alleviate pressures. As a result, the old A5 was re-opened to vehicles not exceeding 7.5 tonnes on 16 June.
