In the late 19th & early 20th Centuries I believe Manchester Victoria had a roadway which left Gt Ducie Street (the A56) between two of the railway overbridges and rose via a relatively lengthy ramp up to the wide island platforms 12 & 13.
The roadway seems to have been used by cabs in the early days, with a booking office & ticket barrier at the top. Later in its life the roadway probably was exclusively for railway-owned road vehicles & late-night newspaper delivery vans, with public access no longer allowed (at least officially).
The roadway and ramp were discussed, and photos posted about seven years ago in
this thread.
Of course, all traces of the former cab road disappeared completely during the redevelopment of Man Vic and the Arena.
