=== Four Bridges ===
Historically, four movable bridges existed along the A554 Tower Road connecting the [[Seacombe]] district of Wallasey with Birkenhead: two between the Great Float and Alfred Dock, one between the Great Float and Wallasey Dock and one between the Great Float and Egerton Dock.<ref>{{citation |title=Birkenhead Docks (photo 46) |url=http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/pages/Bir%20Dks%20046.html |df=dmy-all |access-date=3 July 2009 |archive-url=https://web.archive.org/web/20110927123119/http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/pages/Bir%20Dks%20046.html |url-status=usurped |publisher=Merseyside Views |archive-date=27 September 2011}}</ref> When originally built, all four were [[Hydraulic machinery|hydraulic]] [[swing bridge]] types. In the 1930s, most were replaced by bascule bridges.<ref name="MVphoto30">{{citation |title=Birkenhead Docks (photo 30) |url=http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/pages/Bir%20Dks%20030.html |df=dmy-all |access-date=3 July 2009 |archive-url=https://web.archive.org/web/20110927123225/http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/pages/Bir%20Dks%20030.html |url-status=usurped |publisher=Merseyside Views |archive-date=27 September 2011}}</ref>

Only two bridges remain, but they remain known collectively as "Four Bridges": a northern red girdered [[bascule bridge]], known as the "A" bridge, and a southern bridge, known as the "C" bridge, which was replaced with a modern flat-deck fixed concrete slab in 2017.<ref name=":0">{{Cite web |last=Hughes |first=Lorna |date=12 January 2018 |title=This is why two of Wirral's famous Four Bridges won't re-open this month |url=http://www.liverpoolecho.co.uk/news/liverpool-news/work-replace-two-wirrals-four-14149241 |access-date=30 June 2023 |website=[[Liverpool Echo]] |language=en}}</ref> Renovation work in the same year also replaced the "A" bridge with a lifting bridge powered by hydraulic rams.
