Rotherhithe
The Rotherhithe Tunnel is a road tunnel under the River Thames. It connects Limehouse in the London Borough of Tower Hamlets north of the river to Rotherhithe  south of the river. A road runs through it called the A101. It was opened in 1908. It is a rare example of a road tunnel where road traffic, pedestrians and cyclists all share the same tunnel. Transport for London took over ownership and maintenance of the tunnel in 2001.
