Le réseau autoroutier SANEF est équipé de nombreux ouvrages de traversée hydraulique. L'un d'entre eux situé sous l'autoroute A1, à hauteur du point kilométrique 75 est constitué d'un double busage en acier de diamètre 1600 mm en passage inférieur vis-à-vis de la section courante. Cet ouvrage étant en acier, il est attaqué par la corrosion. Il est également mis en évidence des problèmes de déversement et de corrosion feuillante des palplanches associées à cet ouvrage ainsi qu'en aval de l'ouvrage, la présence d'affouillements et de maçonneries dégradées Il s'agira donc de nettoyer l'ouvrage, puis de réhabiliter l'ouvrage par chemisage et de procéder à des opérations de réparation pour les ouvrages associés à l'OTH.
