YOU are probably overwhelmed with letters on this subject but this week a letter from a local resident appeared stating the amount of revenue collected through tunnel tolls.

The cheapest is the £1.50 Fast Tag and if 25m vehicles a year pass through that would be over £37m and the top fee with a Tag is at least £5.60.

As your other letter-writer has asked, "Where does all that money go?" 

The Birkenhead Tunnel is often closed.

Surely it's time for these tolls to be no longer a cash cow for other purposes.

Wirral tunnel-user, name and address supplied.
