The tunnels are used for road vehicles, pedestrians, Underground and railway lines and utilities.
The figure and list above leaves out a tunnel to the site of the old Ferranti power station on the east side of the mouth of Deptford Creek.
There is also a tunnel between Cottons centre and the old Billingsgate Fish Market near to London Bridge.
The Thames Tideway Tunnel, due for completion in 2025, will be a 25 km (16 mi) long tunnel running mostly under the tidal section of the River Thames through central London to capture, store and convey almost all the raw sewage and rainwater that currently overflows into the river.
Consequently, railway builders have had to tunnel under the river in the city centre rather than bridge it.
