The south portal of Netherton Tunnel.

Netherton Tunnel, in the West Midlands, was the last canal tunnel to be built in Britain. It opened in 1859 and provided a waterway connection between the Black Country towns of Netherton and Tipton.

It runs under the Tividale Hall estate near Dudley and an air-vent which lets light into the canal stands in the middle of Aston Road. Another air-vent stands between two houses in Regent Road. The southern mouth of the tunnel is below Warrens Hall Park on the border of Dudley and Rowley Regis. The northern mouth of the tunnel is near Dudley Road West near Tipton's border with Oldbury.

The air vents that run along the tunnel are know by the locals as "pepper pots", because of their shape.
