Looking at the workers on the construction site, wearing work uniforms marked with the traditional yellow of the City of a Thousand, it is easy to guess that the Urban Municipality of Antananarivo (CUA) is overseeing minor works on the traffic island along the Route des Hydrocarbures in Ankorondrano. What a shame! It is equally easy to imagine that the concrete blocks erected between each pedestrian crossing, located on either side of the road, are intended to stop two-wheelers seeking shortcuts, even if it means abruptly cutting across the line of cars traveling in either direction. An accident-prone maneuver that justifies the implementation of such a makeshift system (D for deterrent) on this expressway, even though traffic is often slowed by congestion. However, this constitutes an abnormal risk for third parties and users of this public infrastructure, which it is under administrative law. Indeed, people, particularly those with reduced mobility, who use it regularly or even occasionally, could trip on these markers and injure themselves. Or even fall directly between cars, without drivers necessarily having the time or reflex to avoid potential victims of "public works damages," for which responsibility falls to the public entity on whose behalf the work was carried out. In this case, it is the CUA, which is legally responsible for accidental and/or permanent damages caused by the structures in its custody. As such, it is obliged to compensate for losses suffered by users or third parties, according to the principles of strict liability, or presumed liability in matters of public works damages, such as those that could be caused by these red and white markers, which are apparently not retroreflective, so that users can see them at night on this poorly lit road. What a shame!
