I think I asked whether there had been a topic on the canal a few months ago. Apparently there hasnít been so I started doing a bit of digging and have found a surprising amount of info about a project which never happened.
Basically, the plans were drawn up by Thomas Telford in 1828 to build a canal between Wallasey Pool and the River Dee at West Kirby roughly following the course of the River Birket. The plans included the building of a dock complex at the Wallasey/Birkenhead end. If the proposals had been implemented the canal would have completely transformed the topography and History
of North Wirral. When Liverpool Corporation found out about the plans they realised that they would have a detrimental effect on their own docks and immediately started buying up land around Wallasey Pool to scupper the plans of Telford and his partners. This in turn affected Birkenheadís History
as the land lay undeveloped until money was found to build the Birkenhead dock system (first part opened in 1847).
I plan to put an article about it on wiki but if thereís anything particular that youíre interested in, let me know.
