“Propylee” is the futuristic walkway designed by French archistars Fabrice Notari and Rudy Ricciotti. This 8-meter-high raised over pass includes also a green area and aims at making the famous “Boulevard du Jardin Exotique”, one of the main entrance routes to the Principality of Monaco, even more suggestive. The works, including NPS® BASIC beams assembly, were carried out during the night, thus ensuring a smooth flow of daily traffic and the lowest impact on the local community.
