PIARC Congresses

Since the first World Road Congress held in Paris in 1908, PIARC has organized the World Road Congress every four years in one of member countries, with the aim to share techniques and experiences worldwide in the field of road infrastructures and road transport.

PIARC has also organized the International Winter Road Congress every four years since 1969.

The 13th World Road Congress was held in Tokyo in 1967, and the 11th International Winter Road Congress was held in Sapporo in 2002.
