The bridge has always been linked to transportation and connection, but what little few know is that it was once directly linked to inhabitable spaces. The idea of the inhabitable bridge was overly used in the medieval ages and soon after the industrial age the bridge was slowly forgotten. These bridges were built due to the high density of population in the cities and building bridges that also functioned as residences and commercial spaces was the most practical and logical solution at the time. Planet Earth is now home to over 7 billion inhabitants and counting. With this increasingly large population, and lack of residential space, incredibly high prices in urban centers, the inhabitable bridge is the only answer that we as a population need to look forward to.
Unlike regular utilitarian bridges, which only support the destinations, the inhabitable bridge creates a destination within itself. Inhabitable bridges offer a new solution to urban cities, they create a destination in the interstitial space that typical utilitarian bridges occupy, space that we have agreed on to be uninhabitable. The construction of mixed-use structures on bridges would save resources but also land which is one of the most precious resources that we have. These bridges would not only serve serve as connections within the city and residences but they would actually pay for themselves in the end. As the taxes paid by the bridge dwellers would go directly to the bridge maintenance, repairs and construction costs. These new bridges are self-sustaining and offer a solution to our ever growing problem.
There are thousands of main span bridges around the world from San Francisco to Dubai, from Montréal to Hong Kong and none of which is utilizing the concept of inhabiting the infrastructure. The importance of reviving the inhabitable bridge is crucial for the survival of our urban cities. It will allow our cities to continue to grow without the need to increase our urban density or the height of our skyscrapers.
The concept for this bridge was creating a skyscraper that resembles the “typical” form of a bridge. This would allow an easier transition for this typology to go from bridge to home. It uses a modular system similar to its neighbour, Habitat 67. By using modular construction the bridge could be built in different phases based on demand, budget, time and constraints, all while being inhabited. It would also allow the bridge to be constructed in a fraction of the cost and at a much faster rate than typical construction. Every major city could utilize this concept and since it is a modular construction, it could be tailored to fit their needs and demands.
The piers of the bridge would serve as more than typical structural elements but as energy providers. With the use of water turbines harnessing the power of the river's current, which in Montréal can go from 3 to 5 knots. The turbines would be located in the center of the columns where they would funnel the water to increase the volume and force which in return would augment the power generated. The two turbines combined could generate enough electricity to power almost 200 regular houses. This would definitely diminish the heighten load that the bridge will need in order to power all the spaces.
This particular bridge was designed for the city of Montréal, Québec which is in need of both residences and bridges. The “Sky Bridge” was the perfect solution for the area not only for its residential and infrastructural demands but for its identity. Montreal has lacked an true landmark that could compete with major cities around the world for the 30 years. This bridge would create that identity, that landmark that would put Montréal back on the map where it belongs, it would be the new gateway into the city and everyone who sees it would remember the city that built the first 21st century inhabitable bridge.
