A £1.8m project to repair a North Yorkshire pier extension is due to begin.
Scarborough Borough Council said Whitby East Pier's foundations had weakened and parts of it were "severely corroded."
In 2009 the council was awarded grant aid from the Environment Agency so it could carry out the repair work.
Work is expected to start on 23 August - after the Whitby Regatta - and last about 15 weeks.
The repairs will involve propping the pier and then cutting a trench in the seabed.
A new wall will be constructed along the base of the pier supported by steel piles.
Scarborough Borough Council project manager Chris Bourne said: "While we appreciate this is the peak summer time, the works are being done at this time of year to take advantage of the good weather and favourable sea conditions.
"If the works were to be delayed until the winter period they would take significantly longer and cost considerably more due to the inability to work in rough seas."
