Location of Three Bridges in London Borough of Ealing
Three Bridges, formally known as Windmill Bridge, is a three-level crossing of bridges in Southall, west London, England.[1] The project was Brunel's last to be finished before he died on 15 September 1859.
As the railway was the most recent addition, the design allowed the railway to be in a deep cutting so it wasn't visible from and didn't enter Osterley Park as well as being economically cheaper.[3][4][5] Work began in 1856, and was completed in 1859.[4]
The structure is a scheduled monument and is adjacent to a homonymous park[6]
