Wrecking teams are poised to tear down a seafront leisure centre deemed too big and old for modern life.
Contractors will be on site from Monday (February 3) at Great Yarmouth's Marina Centre, and say it will be levelled within three months.
After two weeks of site set-up the sprawling complex - once hailed as the answer to Yarmouth's tourism needs - will be cleared ending four decades on the Golden Mile.
Construction of the replacement £26m water and leisure park will begin in late spring ready for Summer 2021.
Material from the old centre will be re-used as part of the groundworks.
In a statement the leaders of the main political groups Carl Smith and Trevor Wainwright, said the start of on-site works was "hugely exciting".
They said "The impressive new Marina Centre will be a game-changer, acting as both a catalyst for potential further investment and an important hub to support community health, well-being, and fitness.

"The old Marina Centre was great in its day but has come to the end of its life, and its redevelopment is an exciting new beginning as part of our regeneration ambitions for the seafront and wider borough.
"This is about the future: the sort of facility we want our children and grandchildren to have and enjoy.
"Over the coming months, we're sure that residents and visitors will watch with interest as the site is carefully levelled and cleared, opening up long-hidden views, and the new state-of-the-art landmark facility takes shape, benefitting the seafront and whole borough for up to 40 years."
The new complex will include a six-lane 25m pool with full disabled access and suitable for competitions and galas, a confidence water area and learner pool with moveable floor, leisure water with fun play features, two water flumes, and a splash pad.
