So I suppose those buses seen on the ferry were running light.



Yes - MOT runs, garage transfers or possibly driver training. When I

used the ferry there was a single decker driver training bus waiting

for the ferry at Woolwich.

Do any bus routes go under or over the river by QEII Bridge or Blackwall Tunnel or any Ferry?

The 108, from Stratford to Lewisham, goes through the Blackwall
Tunnel. It has to use single deckers because of the clearances in the
northbound tunnel.

Ensignbus's X81 uses the Dartford Crossing to run between Chafford
Hundred and Bluewater.

No bus services use ferries across the Thames.

In times past there was a minibus operated route through the
Rotherhithe Tunnel (P14 then 395) but TfL withdrew the 395 without
replacement. Width restrictions have been added since then which make
bus operation impossible through the Rotherhithe.

Others can add in the older history of LT bus operation through the
tunnels if they wish.

From 1927 to 1951, the 108 through the Blackwall Tunnel (two-way
traffic in the original bore in those days) used special-bodied
double-deckers with "domed" roofs (reduced height at the sides) and
tyres with steel-reinforced walls to cope with the frequent rubbing
against the kerb that was necessary to pass other traffic. Initially NS
and later STL. Standard STL and RTL/RT buses were used from 1951 to
1968, LT having persuaded the police that special bodies weren't really
necessary.

I didn't realise that after the 2nd bore was opened in 1967, they raised
the carriageway level in the old bore in order to provide more width,
which reduced the available height and prevented use of double deckers
when it reopened. More details at
