All nine of the bridges were constructed as part of the London & Bristol Railway, otherwise known as the Great Western Railway (GWR), engineered by Isambard Kingdom Brunel and built and opened in eight sections between 1835 and June 1841. They are all located on the first section of the railway to be completed (from Bishop’s Road, London to Maidenhead Riverside), opened on June 4th 1838. These nine overbridges were originally of a single span. Each has been extended at least once, but all retain significant elements of their original fabric, most notably their main 30ft span semi-elliptical arch over the railway. All of the bridges are examples of a single generic bridge type, constructed in the United Kingdom in thousands during the 18th and 19th Centuries, in order to carry lesser roads and lanes over canals and railways.
