The section of promenade under Eastbourne Pier should be open in time for the town's annual airshow which starts on Thursday.
Structural engineers have confirmed that the pavement is safe and that the pier flooring, which runs over the top of this section of promenade, is in good condition.
Work is underway to create a colourful montage of images on the fencing around the pier.
The montage, funded by Eastbourne Borough Council, will show the history of the pier and give a timeline of when repair work will be carried out.
On Saturday, the clean-up operation started. Debris is being loaded into skips and repair work is progressing to make the site safe for the September opening.
An entry and an exit route are being prepared so that the end of the pier venue can be brought back to life as swiftly as possible.
