Why not just abandon the transport levy? You now can't park anywhere near the Amex unless you are 1901 or pay for the uni or the Bridge car park. No dropping off should be easily enforceable on the A27. So what's the problem? Other than walking or cycling you can only realistically get there by...
I've no idea if this is a good or bad thing. No idea what they intend to put in its place. Etc,., etc.
However the way this news comes out, via the bus company, appears to be pretty typical of the level of communication skills at the Amex. I can see some cost saving there.
