Journeys to and from South Wales will take longer for the next fortnight with the closure of the Severn Tunnel for engineering work.

The four mile route under the river will bee closed until Friday 20th June, as well as Sunday 29th June.

Network Rail will be undertaking essential track renewal and maintenance work and during this time trains between London and South Wales will use an alternative route between Swindon and Newport – stopping at Gloucester instead of Bristol Parkway.

Passengers travelling between Bristol and South Wales can change at Gloucester or Cheltenham Spa, where trains will still be running to and from South Wales. A limited train service will still run between London Paddington and Bristol Parkway. Replacement buses are also planned between Bristol Parkway and Severn Tunnel Junction/Newport, but these will be limited services only.

The exception is on Sunday 15th June, when rail replacement services are planned to operate between Bristol Parkway and Newport or Cardiff Central on this date. Trains will still run between London Paddington and Bristol Parkway, plus between Newport and Swansea or Carmarthen.
