Mayenne department in France maintains a dataset of specific points on exceptional transport routes that may hinder or damage convoys. These crossings, which include structures like bridges, gantries, and traffic lights, are identified and validated by prefectural decrees based on agreements with infrastructure managers. The dataset was published by the Bureau de Recherches Géologiques et Minières and last updated in November 2021.
