ASCE hosted a national student steel bridge competition which required architecture and interior design students to pair together to revitalize Philadelphia's Reading Terminal Viaduct. To serve as a connecting terminal from the Reading Viaduct to Center City’s redeveloping neighborhoods, Skywalk is a preservation tactic for the elevated train tracks that have been abandoned in the 1980s. To tie back to the theme of a Skywalk, the bridge crosses over the Vine Street Expressway which allows for an overview of the neighborhood and a view of the Philadelphia Skyline. To establish a relationship between the bridge and the surrounding city, a conceptual theme for lightness is shown with the use of mirrored glass on the exterior to camouflage the space in with the sky while hiding the interior walkway through the museum. With this incorporation of immateriality, the use of a support base system is emphasized through a cable-stayed/ suspension bridge which gives the illusion of a floating space. Railways play a big role in transition into the industrial ages and throughout history, materials such as concrete and steel have provided the basis for bridges. As for Skywalk, concrete is the structure for the pathways including the walk-able pathway leading the roof of the inhabitable space. This path takes more of a scenic route with the use of green spaces to contribute to the sustainable innovations used in this project which serve as intensive vegetated living roof to catch storm water run-off and protection from sun exposure.
