Höweler + Yoon Architecture has developed the "Shareway," a concept that unites communities along Interstate 95 between Boston and Washington D.C., into a mega-region called "Boswash." The concept "focuses on community access and seeks to bundle transport into a highly technical, optimized and continually flowing main artery," Donna Taylor writes. The artery is like a stacked highway, with each level serving different transportation needs. "Through a combination of physical infrastructure (hardware) and intelligent networks (software), Shareway makes travel effortless and reconfigures the structure of cities and suburbs," the architects note. "Proximity is a function of time and location. Geography is negotiated by speed. Distance is displaced by access. Convenience is remapped through new forms of conveyance."
