Blackwall Tunnel opened 22nd May 1896

Over 120 years after it was built, the Blackwall Tunnel remains the main river crossing East of Tower Bridge, connecting the East End to South East London. It may be a surprise to learn that a late Victorian Londoner, would have the same inner London river crossing options as a Londoner today.

In the mid-1850s Londoners had 3 toll-free river crossing options, London Bridge, Westminster, and in the middle Blackfriars. Victorian planners saw the need for building additional river crossing capacity for the 40% of the London population that lived in the East of the city. The Metropolitan Board of Works (MBW), set up in 1855, worked over a 30 year period to solve the river crossing problem. The solution came in 1885 by way of an act of parliament to build what would be known as Tower Bridge and further down the river, a tunnel which would be called Black Wall Tunnel

When the Blackwall Tunnel only had one

Traveling southbound through the Blackwall tunnel today you will notice the engraved stone above the tunnel entrance bears the date 1967. Today’s northbound tunnel bears the date 1897. Victorian engineer Alexander Binnie designed a single tunnel with sufficient width for north and southbound traffic.

When you look back in our history, especially on matters of city planning, you get the sense that the time scales are counted in decade jumps. The victorian city planners were building their tomorrow, and no their today. The decision to go with a single tunnel solution for the Blackwall tunnel would take another 80 years for a second tunnel to be built, ironically the original plan in 1885 by Sir Joseph Bazalgette, was for a twin tunnel solution.

The approval for the Single tunnel was approved by the London County Council in 1891 with a tender going to S. Pearson & Son of Victoria Street, at construction cost of £871,000.

27 Foot wide, 6000 feet long the largest tunnel of its time

At the time of planning, 3 other notable tunnels existed, City and South London Railway Tunnel (1886–90), the Hudson River Tunnel in New York (1879), and the St Clair Tunnel in Canada (1889). None of these were as big as the Blackwall tunnel project.
