This project looked at Baltimore as an example of a modern city that is still shaped by massive infrastructural constructions of the latter 20th century. Baltimore, like many cities, went through a period of dramatic change as large swaths of the city were demolished to make way for high-speed, multi-lane roadways. This period of infrastructural urbanism began at a time when social inequality was codified in the city by discriminatory housing policies. These roadways have both reinforced these inequalities and subverted the city’s natural systems. In this project, a green-way system with multiple 3D-thresholds was proposed to deal with both the physical disconnections and the community isolation caused by existing infrastructures in the city. These 3D-thresholds would function as gateways in the greenway system inside the city to reform the city's identity and proud.
