The current Mersey rail tunnel only handles 40% of its capacity. Use computerised signalling systems as on the London Jubilee line, which keep trains 30 seconds apart and there is nor need for a new crossing.
I went to a concert at the O2 in London and only 18,00 turned up, yes only 18,000. At the tube station there was a massive line of people. I was expecting a 1 hour wait to get in. I was inside and home near Central London in 50 minutes after concert end. The trains were coming in thick and fast.

The only Mersey crossing I can see happening is on a new barrier at New Brighton.
Depending on the approach roads a tunnel "can" be cheaper than a bridge. The Mersey had tunnels for defence reasons.
The bottom of the Queensway tunnel still can be used for trains. Well from Morpeth Dock vent tower to George's Dock vent tower.
