The original Mersey road tunnel (Queensway) was designed to have a twin tram track in the lower half. The current road deck fits across the diameter of the tunnel leaving half the space beneath free (it is of course used for maintenance, vehicle and material storage)
from "The Story of the Mersey Tunnel, officially named Queensway"
"In this, the original scheme, through tram services between Liverpool and Cheshire boroughs were a prominent feature. It was for that reason that the great diameter of 44 ft. was provided for throughout, except in the branches, a diameter sufficient for four lanes of traffic on the upper deck and two sets of tram rails on the lower".
The tram plan seems to have been abandoned at the same time as the Wallasey and Bootle tunnels were (these were two potential routes rather than to Birkenhead as built...it seems Birkenhead obected because it would be in competition with its ferries).
