If a new pier was built, it wouldn't be anything like the old New Brighton Pier.
The last completely new pier, in Deal, Kent, was concrete, and Bournemouth pier was also rebuilt in the 1950s, in concrete.
I lived in New Brighton in the early 1970s, when the ferry was still in operation, but it was evident even then that Wirral Council wanted NB to be residential, and not a holiday resort.
