A new Pont Briwet bridge that will carry the Cambrian Coast railway line over the Dwyryd estuary is opening on Monday after being hit by delays.
It has replaced the 154-year-old bridge in Penrhyndeudraeth, Gwynedd, which was shut over safety concerns.
The £20m EU-funded project includes the installation of a rail bridge and a two-lane vehicle bridge along with a cycle path.
Ben Davies from Arriva Trains Wales told BBC Radio Wales that the line is important to many local people between Harlech and Pwllheli and that it was a "wonderful day".
