ONL [Oosterhuis_Lénárd] has won the prestigious design competition for a 1.8 kilometer long barrier of silence along the A2 highway at Haarrijn, Utrecht (NL). This new barrier will protect the future residential development “de Haarrijnseplas” from the sound of the A2 highway and it will merge with the commercial buildings in the industrial zone. This fusion creates a coherent architectural image from a series of incidents.
