Ship impact is a major consideration in the design of bridges. Forces calculated using the various methods in use can be very large and vary considerably. This paper describes the method used in the design of the Hungerford footbridges over the River Thames in central London, UK, and compares the results with other methods. Eurocode 1 is shown to produce large variations, depending on which method is used. The design and construction of the ship impact protection for Hungerford Bridge is also described.
