At Somerleyton the Lowestoft to Norwich railway line crosses the Waveney on a swing bridge, while at St Olaves, the Haddiscoe Cut branches off left to connect the Rivers Yare and Waveney. The Cut was excavated in the 19th century to provide a direct route between Lowestoft Docks and Norwich. Finally the Waveney flows past Burgh Castle into Breydon Water at the confluence of the two rivers. It now forms part of the river Yare and reaches the sea at Great Yarmouth.
