Examines the detailing that is peculiar to a concrete bridge and which need to consider buildability, durability and maintainability as well as safety and aesthetic issues.  The weather is the main source of concern for most external details, with water, often laden with salt, able to reach almost everywhere.  Every surface must therefore be detailed on the basis that it will get wet – this requires a positive drainage and drip system for all near-horizontal surfaces.  To protect details within the concrete, the characteristics of the concrete must be specified, which will depend on particular site conditions.  Working to these specifications will ensure that the concrete is best suited to its location, in order to provide a low maintenance working life.
