There used to be a battery of three culverts in the stream under LA1 Road at km 19.8. An exceptionally high flood that occurred in the late spring of 2018 caused the battery of culverts to give way. They were completely swept away by the current, and the road collapsed. A temporary bridge was constructed urgently in the following days, and in fall 2018, another temporary bridge of higher capacity was built in the Road LA1 axis.

Due to technical and operational constraints, the Société de développement de la Baie-James decided to split the work contract into two phases spaced over time. The life of the temporary bridge was extended to cover the period from fall 2018 to summer 2019, and construction of the permanent structure was postponed to summer 2019.
