Opening 22 May 1897 of the Blackwall Tunnel

The Blackwall Tunnel is a pair of road tunnels underneath the River Thames in east London, England, linking the London Borough of Tower Hamlets with the Royal Borough of Greenwich, and part of the A102 road. The northern portal lies just south of the East India Dock Road (A13) in Blackwall[a]; the southern entrances are just south of The O2 on the Greenwich Peninsula.https://en.m.wikipedia.org/wiki/Blackwall_Tunnel#cite_note-5 The road is managed by Transport for London (TfL).

Ninasikia watumwa waliosalia baada ya biashara ya utumwa kukomeshwa, wengi walifia katika kazi za vibarua kujenga hii barabara ndani ya mto.
