Crossings of the River Shannon

O'Brien's Bridge

The Crossings of the River Shannon are several and varied, including bridges, tunnels, ferries and fords, as the River Shannon is the longest river in Ireland, running from its source in the Shannon Pot to the Shannon Estuary where the river widens and enters the Atlantic Ocean.

Bridges not primarily intended for public use but which have limited access (generally only in the daytime and only for bicycle and foot traffic) are not included.
