The car park at Pengam railway station will be closed to the public on Sunday 22nd November to enable drainage works to be carried out at the site.
The works form part of site investigations in advance of a major scheme to create a new Park and Ride facility at the station next year. The development will see the car park expand to include around 170 parking spaces.
The scheme is a partnership between Caerphilly county borough council and Sewta, with funding from the European Regional Development Fund and the Welsh Assembly Government.
Alternative Park and Ride facilities are available at Bargoed, Ystrad Mynach and Caerphilly during the closure on 22nd November.
