The pedestrian footbridge that at in the northern entrance of the municipality of Azagra (Navarra) suffered the collision of a tractor that circulated with its shovel lifted. The structure of the footbridge is formed by a spatial mesh of steel bars, with spherical knots of solid steel. The aforementioned impact caused the fall of one of the knots along with the disabling of the incident bars in it.

Despite the impact, the structure maintained a configuration that made possible a new equilibrium scheme, thanks to the moderate internal redundancy of the original mesh.

Windmill designed and calculated the necessary reinforcement to reopen the walkway to the public with a sufficient safety margin.

It should be noted that it has been necessary to carry out a spatial evolutionary calculation that has contemplated two phases: the post-impact situation and the post-reinforcement situation.
