Obviously what's missing here is any cross-river connection, and to

it's a tiny tunnel, unsuitable for anything more than minibuses.

LT used to run double-deckers through the original single-bore
Blackwall Tunnel (routes 108, 108A) and also Rotherhithe Tunnel
(route 82). They were modified STLs with a different roof profile
and tyres with specially reinforced sidewalls to protect them from
frequent contact with the kerbs in the tunnels. Details at

According to http://www.londonbusroutes.net/photos/395.htm, there is
a
7'6" width restriction. But I thought several of the single-decker
classes like the DP were 7'6" wide (2.29 m). So why can't they
be used?

Blimey - I knew that there were double-deckers through the Blackwall
tunnel, but not the Rotherhithe tunnel! That must've been a squeeze.

Don't forget that buses were all 7'6" wide until the 1950s. ISTR a a more
pronounced arch-shaped roof line than shown at that URL but there you go.
