That is what I believe the police are supposed to be trying to do - get the away fans out in the south east corner and up bloomfield road to central drive than back towards town for coaches, trains etc. So that's why they're trying to stop home fans from the north going onto central drive. It inconveniences home fans wanting to go inland up bloomfield road, but that would really still be the case if the away fans came out on back henry street.
Last night, there were signs on seasiders way telling away fans to use foxhall and central car parks - so they're trying to stop the away fans needing to go back towards lonsdale and bloomfield car parks and the armfield.
The plan kinda makes sense, but it needs implementing properly on the ground. The flashpoint v nobbers was because home fans trying to get up bloomfield road were forced along st heliers, and the away fans went down saville because of congestion filtering to central drive.
The police need to manage this properly, and they also need to manage the car parks to stop away fans parking on the main carparks west of the ground.
Unfortunately, home fans need to avoid bloomfield road/central drive/revoe after the match. But I would anyway, TBH.
