In the case of an old brickwork bridge over the railway, the ultimate responsibility for the structure of the bridge tends to fall on the railway company, as the freeholder of the bridge. However, if the damage is caused by traffic regulations allowing vehicles to damage the structure (too many heavy lorries, travelling too fast), then the responsibility will pass back to the highway authority. With a modern bridge, built as part of a modern road system, the bridge will typically be owned by the highway authority, who will have the duty to maintain it. This Q&A refers to ‘railway bridges’ which are a special category, due to the fact that most of them were constructed by the railway companies in the Victorian period, rather than by the county councils in the post-war era.
