Britannia Bridge (Pont Britannia in Welsh) is a bridge across the Menai Strait between the island of Anglesey and the mainland of Wales. It was originally designed and built (1846-50) by Robert Stephenson as a tubular bridge of wrought iron rectangular box-section spans for carrying rail traffic. Snowdonia: Britannia Bridge is a scenario for Snowdonia created by designer Tony Boydell and publisher Indie Boards and Cards to commemorate the second edition of the game; this scenario is available directly from IBC at conventions. Snowdonia: Britannia Bridge includes a trio of tweaked contract cards and a new engine – The Dawn Raider – that allows its owner to build track instead of the game (if he wants) whenever the game would build track due to an event.
