Up to 20,000 fans are expected to turn out for Brighton and Hove Albion's victory parade on Saturday.
Rolling road closures will be in place to cope with the crowds as people celebrate the club's Division Two championship triumph.
Police today warned fans to stay out of the roads and remain inside coned areas for their safety.
The parade begins at 11am as the Albion stars leave the Palace Pier. They will travel along the seafront reaching Kings House, at the foot of Grand Avenue, at about noon.
The players will appear on the balcony between 12.30pm and 1pm.
During the parade, westbound traffic will be directed away from the A259.
Police are warning motorists Brighton and Hove will be very congested and are urging people not to drive into the centre.
Grand Avenue will be closed to southbound traffic and one lane of the northbound carriageway will also be closed.
Superintendent Peter Coll said: "This procession is a family event which will give all of the Albion's fans a chance to join in the celebrations.
"I am anticipating a good-natured, fun morning."
