I have mentioned the Newport transporter bridge, but today Jonathan Calder provides a film about the larger [Widnes to] Runcorn transporter. There are barges and cars and all sorts.
It always strikes me as odd that Liverpool has no bridges and that you have to go miles upstream to Runcorn to cross (if you want to be above water and not on a ferry, although the ferry trip is a wondrous thing in itself).
Of course Runcorn itself didn’t always have a bridge. Before that you had to cross by ferry, per tuppence per person per trip.
