Longest inland waterway without a crossing

Trying to settle a bet. I believe the longest stretch of inland waterway in Ireland without a crossing is the Munster Blackwater between Youghal and Cappoquin. It’s 18.62 km as the crow flies. By road it is either 26.3km on one side of the river or 29.8km on the other side. A 30 minute drive on either side.

Can this be beaten?

Completely forgot about Lough Derg and Lough Ree.

Same question but excluding lakes.

Killaloe Portumna

My bad, excluding lakes and harbours I don't know of any

Edit: assuming you means roads (it is the roads forum) Banagher to Ballinasloe

Banagher to Portumna

Shannon Estuary?

The estuary wouldn't be classed an inland waterway.

The Shannon is tidal from above Limerick.

Youghal to Cappoquin is also tidal.

I’d reckon it is River/Lough Corrib between the Quincentennial Bridge in Galway city to its western end in Connemara. That’s 30 miles or 50 kilometres.

I know that’s a lake, but it’s the longest section of inland waterway in Ireland I can think of without a bridge.
