Car Parking v Hull

Uni parking closed for an event so using Bridge.
To avoid two 400 mile trips in 4 days we are coming down in our Campervan and having a mini holiday in Sussex. Never normally a problem but checked it out on Saturday and the tunnel is too low. Is there another access point for Bridge please?
Also is the disabled minibus running or do we need to bring a wheelchair and push up to the Amex?

Many thanks

Assuming you have seasonal parking then nothing should change – those with designated disabled parking bays in Sussex (so they have a disabled badge on their parking pass) will be able to stay in Sussex for these games.
