Northampton Arm (Grand Union Canal)

A lifeline during lockdown

Local waterways have been an escape for many during these difficult times. Our work to protect them is more urgent than ever.

The Northampton Arm leaves the Grand Union Canal mainline at Gayton Junction and joins the River Nene in the centre of Northampton.
