A canal junction is a place at which two or more canal routes converge or diverge. This implies a physical connection between the beds of the two canals (commonly in the form of a T junction) as opposed to them crossing on different levels eg via an aqueduct.
Where the canals were originally owned by different companies there is often a stop lock at the junction.[1]
In some cases, the creation of a canal junction caused a town to grow up alongside.
