'''Hammersmith Bridge''' is a [[suspension bridge]] that crosses the [[River Thames]] in west [[London]]. It links the southern part of [[Hammersmith]] in the [[London Borough of Hammersmith and Fulham]], on the north side of the river, with [[Barnes, London|Barnes]] in the [[London Borough of Richmond upon Thames]], on the south side of the river. The current bridge, which is [[listed building|Grade II* listed]] and was designed by [[civil engineer]] Sir [[Joseph Bazalgette]], is the second permanent bridge on the site,<ref name=listing>{{NHLE |num=1079819 |desc=Hammersmith Bridge |date=12 May 1970 |access-date=26 May 2015}}</ref> and has been attacked three times by the [[Irish Republican Army|IRA]].

The bridge was closed indefinitely to all motor traffic in April 2019 after cracks were discovered in the bridge's pedestals.<ref>{{Cite news |url=https://www.bbc.com/news/uk-england-london-47891838 |title=Hammersmith Bridge 'closed indefinitely' |date=11 April 2019 |work=[[BBC News]] |access-date=12 April 2019 |language=en-GB}}</ref> The closure was extended to pedestrians and cyclists between August 2020<ref name=ESAug20>{{cite web |title=Hammersmith Bridge fully closed following fresh safety concerns |url=https://www.standard.co.uk/news/london/hammersmith-bridge-closure-a4524336.html |website=Evening Standard |access-date=13 August 2020 |language=en |date=13 August 2020 |first=Daniel |last=O'Mahony}}</ref> and July 2021 when limited use resumed.
