Construction of the Chabanne wildlife crossing

As part of the 2×2 lane project of the RN2 at the Vaumoise bypass between the Aisne and the Oise, Matière was asked for the construction of a wildlife crossing.

This biological corridor of Chabanne is 25m wide and consists of 2 reinforced concrete vaults surmounted by a ground cover. The wildlife pass is between the communes of Coyolles and Vaumoise in the Oise.

The parts of this structure were manufactured in our Souleyrie factory
