Abstract: This invention discloses a set of components that have been designed and engineered and have functionalities, dimensions and structural properties specifically intended to enable selected combinations of the components to be assembled into modular sections of an enclosed and elevated roadway suitable for bicycles, other small vehicles and pedestrian walkways. Such modular sections can, in turn, be joined together and interconnected so as to form a network of roadways that include main thoroughfares and branches and other desired functions such as rest stops and parking facilities. Furthermore, the disclosed set of components enables a process to plan, design, engineer and configure networks of enclosed and elevated roadways to serve a specific municipality, campus, military base or any other geographical region.
