We recently showed you a wonderful trampoline bridge in Paris, now we head over to Russia to discover a trampoline sidewalk built by Salto Architects for this year's Archstoyanie Festival. By challenging traditional concepts of infrastructure, the architects were able to design an intelligent commuter lane that is emotional and corresponds to the local environment. WTF, America. Can we live? Hit the thumbs to explore Russia's "Fast Track" trampoline sidewalk in full detail.
