PUBLIC PATH




This design applies an inverted interpretation of modern society’s harvesting principles.
Instead of harvesting energy from society itself, the design proposes to collect and recycle the energetic waste that is transportation.
This bridge performs as a self-sustainable organism, propelled solely by it’s primordial program, human circulation feeding an energetic closed-circuit (energy production is generated by the main program) which illuminates itself and the surrounding areas.
The programatically binomial bridge directly reflects two distinct behaviors - translated into two different speeds of interaction.
This proposal hence rejects usual typologies for cyclist and pedestrian bridges (trajectories such as rotation, zig-zag or others), but instead proposes a continuous straight path where the linear height variation becomes more natural and easier to overcome.
The binomial program on this bridge is, by default, split, as we are facing different speeds and different translation movements (smooth for bicycles and stepped for pedestrian). Still, both programs are symbiotically intertwined, interacting as a unified extension of the proposed and existing surrounding circulations and landscape.

In this linear typology, the apparent disadvantage of a larger span, becomes an advantage due to it’s natural site integration:
- the bicycle path is an instinctive continuation of the desired paths on both sides.
- the pedestrian path is a stepped landscape that flows into the existing site spreading connective paths over variable surrounding topography.

SELF SUSTAINABLE BRIDGE
Piezo Field/ Perforated Facade
Energy can be collected through piezoelectric materials when stress is applied. The design integrates piezoelectric-arrayed pathways within both circulation paths (cyclists and pedestrians) along the bridge.
As people move through the bridge, energy is collected. The crowd generated electricity is then fed back from the floors into the walls. These same walls are populated with LED lights which illuminate the bridge through the perforated facade
The Piezoelectric paths collect and store energy, establishing a looped chain reaction of farming energy and supplying instant feedback.
The facade therefore performs at two different levels, illumination and ventilation, having complementary patterns on each side which establish an even amount of perforation along the bridge for illumination and ventilation.
