The Hertford Union Canal is a short canal in East London which stretches from the Regent's Canal to the Lee Navigation. Like the Limehouse Cut the Hertford Union Canal is intended as a short-cut between the Thames and the Lee Navigation. It was opened in 1830 and later taken over to form part of the Grand Union Canal system.
The canal is completely straight for its 1.5km length though has 3 locks. For much of its length the canal runs alongside Victoria Park. At its Lee Navigation end the canal junction is in view of the Olympic Stadium and Park.
