Unlike in Liverpool, where the docks were built along the coastline of the River Mersey, Birkenhead Docks were designed as an inland system by enclosing the tidal inlet of Wallasey Pool. The construction of a cofferdam enabled land reclamation and excavations to take place. After the establishment of the Great Low Water Basin, Morpeth Dock and Egerton Dock,{{citation|url=http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/1850-map.htm |title=Birkenhead Docks map (1850) |publisher=Merseyside Views |access-date=13 October 2007 |url-status=usurped |archive-url=https://web.archive.org/web/20061023150644/http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/1850-map.htm |archive-date=23 October 2006 }} the Great Float was formed between 1851 and 1860 from most of what remained of Wallasey Pool. The plans for its construction were originally shown in 1844 in the Liverpool Standard newspaper.{{harvnb|Bidston|1978|pp=12–13}} Designed by James Meadows Rendel, protégé of Thomas Telford, the scheme was managed by the Birkenhead Dock Company until a financial crisis in 1847. The docks were taken over by the Liverpool Corporation in 1855.{{harvnb|Pevsner|Hubbard|2001|p=87}} By 1858, the rights to dock ownership and revenues were transferred to the Mersey Docks and Harbour Board, based in Liverpool.{{harvnb|Brocklebank|2003|pp=34–36}}

Graving docks were built in 1864 and 1877, on the south side of West Float.{{harvnb|Ashmore|1982|p=156}} Established in 1853, Thomas Brassey's Canada Works was built to the east of the Great Float. The entrance to the Great Float was originally through the Great Low Water Basin, which was enclosed in 1877 as Wallasey Dock. After this date, access from the river was provided via Alfred Dock and Morpeth Dock.

The Resurgam, one of the first submarines, was tested in the Great Float in 1879.

In the early 20th-century, Birkenhead Docks became an important flour milling centre, with numerous companies, including Joseph Rank Ltd and Spillers, located on the Great Float's quaysides. In the 1990s, long after the industry had gone into decline, most of these buildings were demolished. Two large warehouses remain, which have now been converted into residential apartments.

The Great Float was the site of the Warship Preservation Trust's exhibits from 2002 until its closure in February 2006.

LCT 7074 Landfall is the last remaining tank landing craft which had served during D-Day. The landing craft was one of the Warship Preservation Trust exhibits and had sunk in East Float following the liquidation of the trust in 2006. The craft was refloated on 16 October 2014.{{cite web|url=http://www.liverpoolecho.co.uk/news/d-day-landing-craft-raised-wirral-7938679|title=D-Day landing craft to be raised from Wirral dock|publisher=Trinity Mirror Merseyside|access-date=16 October 2014}}{{cite web|url=https://www.theguardian.com/uk-news/2014/oct/15/d-day-tank-carrier-landfall-refloated-liverpool|title=D-day tank carrier Landfall refloated for restoration|publisher=Guardian News and Media Limited|access-date=16 October 2014}}

The following docks were originally accessible from the Great Float:

In addition, three graving docks existed in the Great Float for ship repairs. Bidston No.3 Dock remains in use as part of the facilities of Cammell Laird Shiprepairers and Shipbuilders Ltd.{{cite web|url=http://www.clbh.co.uk/facilities/bidston-repair-birth|title=Bidston Repair Berth|publisher=Cammell Laird|access-date=31 August 2016|archive-url=https://web.archive.org/web/20160821054445/http://www.clbh.co.uk/facilities/bidston-repair-birth|archive-date=21 August 2016}} The other graving docks were filled in during the 1980s.{{citation

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.{{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}} When originally built, all four were hydraulic swing bridge types. In the 1930s, most were replaced by bascule bridges.{{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}}

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.{{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}} Renovation work in the same year also replaced the "A" bridge with a lifting bridge powered by hydraulic rams. Work was expected to be completed by November 2017 but, due to complications, the bridge was not reopened until 28 June 2018.{{cite web |title=New dock bridge opens |url=https://wirralview.com/news/new-dock-bridge-opens |access-date=29 June 2018 |website=Wirral View |language=en}}File:Duke Street Bridge - geograph.org.uk - 588922.jpg

Joining the southern end of the Poulton district of Wallasey with the north end of Birkenhead, Duke Street bridge is also a bascule bridge but with painted green girders. Originally, it was a swing bridge.

Furthest upstream is the Penny Bridge, on Wallasey Bridge Road, which crosses the head of the pool to connect Poulton with Bidston in Birkenhead. Replacing an earlier wooden bridge of 1843, the name derives from the 1896 one penny toll to cross in one direction.{{cite web|url=http://www.mikekemble.com/mside/wallasey1.html|title=Wallasey History (page 1)|first=Mike|last=Kemble|access-date=3 July 2009|url-status=usurped|archive-url=https://web.archive.org/web/20090722165224/http://www.mikekemble.com/mside/wallasey1.html|archive-date=22 July 2009}}{{cite web|url=http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/pages/Bir%20Dks%20021.html|title=Birkenhead Docks (photo 21)|publisher=Merseyside Views|access-date=3 July 2009|url-status=usurped|archive-url=https://web.archive.org/web/20080331094401/http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/pages/Bir%20Dks%20021.html|archive-date=31 March 2008}} The bridge was replaced again in 1926{{citation |url=http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/pages/Bir%20Dks%20022.html |title=Birkenhead Docks (photo 22) |publisher=Merseyside Views |access-date=3 July 2009 |url-status=usurped |archive-url=https://web.archive.org/web/20080404041102/http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/pages/Bir%20Dks%20022.html |archive-date=4 April 2008}} and provided access to Bidston Dock. The bridge was replaced by a new swing bridge in 1996 but since the dock itself has been filled in the mechanism has fallen into disrepair through lack of use and the bridge is now effectively a static structure.

Jesse Hartley, who was responsible for many of Liverpool's maritime structures – including the Albert Dock, designed the Central Hydraulic Tower and Engine House (the tower is an accumulator tower). Providing power for the movement of lock gates and bridges at Birkenhead Docks, it was completed in 1863. The design of the building was based on the Palazzo Vecchio in the Piazza Della Signoria, Florence, Italy. In March 2021, it was announced that the building would be brought back in to use as a Maritime Knowledge Hub and will be a national base for marine engineering research and development and survival training as well as providing business accelerator space for the maritime sector. The project will cost £23m.{{cite web |url=https://www.birkenhead.news/ambitious-plans-agreed-for-wirral-landmark/ |title=Ambitious plans agreed for Wirral landmark |author= |date=5 March 2021 |website= |publisher=Birkenhead News |access-date=26 May 2021 |quote=}}

Peel Holdings announced on 6 September 2006 the Wirral Waters project. This would allow for a £4.5bn of investment in the regeneration of the dockland area. This equates with an investment of over £14,000 for each of the 320,000 population of Wirral. At the East Float and Vittoria Dock, the development would include several 50-storey skyscrapers, {{convert|5000000|sqft|m2|-3}} of new office space and {{convert|11000000|sqft|m2}} for new residential apartments. A retail and leisure quarter at the former Bidston Dock site would encompass another {{convert|571000|sqft|m2|-2}} of space. The whole project is estimated to create over 27,000 permanent new jobs, aside from the employment required for construction and other peripheral employment.{{citation|url=http://www.peelwaters.co.uk/pdf/W_050906.pdf|title=Peel unveil plans for £4.5 billion 'Wirral Waters' scheme|publisher=Peel Waters|date=5 September 2006|access-date=3 July 2009}}{{dead link|date=October 2017 |bot=InternetArchiveBot |fix-attempted=yes }}
