APIExecutable4/7Query nowOpen workbench Subscribe🇫🇷France

This dataset lists height clearances and weight limits for bridges on departmental roads, published via the Issy-les-Moulineaux open data portal. The values reflect restrictions indicated by road signage or the load-bearing capacity of the structures themselves. It provides a free, authentication-free API for accessing bridge clearance and weight-limit information at national scope in France, useful for route planning, freight logistics, and infrastructure management where vehicle dimensions or weight could exceed the constraints of a given crossing.Gabarits et limitations de poids des ponts sur les routes départementales. Ce jeu de données détaille les gabarits des routes départementales. Les valeurs présentées correspondent aux limitations imposées par les panneaux de signalisation ou à la résistance aux charges des ouvrages. Ces informati...
