A series of steps that lead to the Brighton coast were closed. So work to restore the arches and the promenade in Madeira Terrace can be continued.
The work began to restore the first 28 of the 151 arches of the terrace in November 2024.
The Royal Crescent steps were closed last month, while the arches were removed 87 to 89 and have now been closed for work on the back wall for two weeks.
The next alternative steps lead from the Marine parade to the Madeira Drive are either on Duke's hill or opposite Rock Place.
Madeira Terrace is a listed grade II, 865 meter long section of the maker and promenade on the Madeira Drive, built at the end of the 19th century.
Between 2015 and 2016, the terrace was closed for public access because the structure was unsure, said Brighton & Hove City Council.
Bungaroosh – stone and brick with calconing – was used as parts of the back wall built to hold the unstable cliff face back in the 1830s.
The Council said that some of the bungaroosh would have to be removed and replaced by modern materials in order to bring them to today's security standards.
Other work includes the reduction of the upper deck and the decrease in the skills and the columns of each arch to send away for restoration.
Working to install a new power supply for the arches begins in the next three months, and the council hopes that the first phase of the backed arches will be accessible to the public in 2026.
