Hammersmith Bridge is a suspension bridge that crosses the River Thames in west London. It enables pedestrians and cyclists to cross between the southern part of Hammersmith in the London Borough of Hammersmith and Fulham, on the north side of the river, and Barnes in the London Borough of Richmond upon Thames, on the south side of the river. The current bridge, which is Grade II* listed and was designed by civil engineer Sir Joseph Bazalgette, is the second permanent bridge on the site, and has been attacked three times by Irish republicans. It was closed indefinitely to all motor traffic in April 2019 after cracks were discovered in the bridge's pedestals.
