Bridge classification number .
The max weight of a vehicle that could cross that bridge.
Two main types, the FBE limited to 9 tons.
Bailey which had a single span capacity of 190 ft for 40 ton loads and 150 ft for 70 ton loads.
Class 40 bridge would take anything apart from loaded transporters that needed the 70 ton bridge.
From
British Army Hanbook, George Forty.
The Formation Sign on the board looks more like XII Corps.
See PeterG's site.

That would fit with page 187 of
Monty' Highlanders Patrick Delaforce as
"...12 Corps made available 621 Field Sqn and 756, 262 Field companies with bridging equipment..."
That was for Operation Ascot 14th-21st November 1944.
