Notes: The Mersey Tunnels connect the city of Liverpool with Wirral, under the River Mersey. There are three tunnels: the Mersey Railway Tunnel (opened 1886), and two road tunnels, the Queensway Tunnel (opened 1934) and the Kingsway Tunnel (opened 1971). The railway tunnel and Queensway Tunnel connect central Liverpool with Birkenhead, while the Kingsway Tunnel runs to Wallasey. (Wikipedia)
