Due to an exceptional flood in the late spring of 2018, the battery of six culverts under the road at km 19.8 gave way causing the road to subside. The planned works consist mainly of:

1. Moving the temporary bridge that was built in an emergency. It must be moved to allow the construction of the permanent structure in the axis of the current road. The temporary bridge will then remain in place during the construction of the permanent arch.

2. Construction of the permanent structural steel arch made of steel over the watercourse.

3. Dismantling of the temporary bridge.
