IIRC, the Blackwall Tunnel buses had special tyres with reinforced sidewalls, because there was a tendency for them to brush up against the quite high kerbs in the tunnel, and they got through normal tyres a bit quickly.on flickr today
bus (some time in the 1930s) emerging from the north end of the blackwall tunnel.
the north end portal (of what's now the northbound tunnel) is still there, but not that obvious, and i've probably only ever seen it in my rear view mirrors.
double deck buses ran both ways through what's now the northbound tunnel until about 1967 (when the new - now southbound - tunnel was then used two-way for a year or so while the old tunnel was modified to be the northbound tunnel - the road surface was raised a bit and the pavements done away with, to make the roadway a bit wider - i'm told it was a bit tight when two buses met)
yes, likewise the rotherhithe tunnel buses (both routes ran from the same garage in Poplar - Athol Street until 1961 then the former trolleybus depot up the road)
Not many know that. Are you a bus enthusiast?
