The infrastructure of a city is determined by the skyscrapers, flyovers, and bridges. The stunning design of bridges has always captured the human imagination. It is an architectural marvel, to construct such pieces. Architects use innovative 3D modeling and virtual design to create different simulations of a bridge structure.
The construction of a bridge involves a complex undertaking of technical knowledge and architectural expertise. A bridge is often built to reduce traffic or to allow pedestrians to connect between two cities or to connect two different places. Aqueducts are the most ancient structures that served as an inspiration to modern-day bridges. They were used to transport fresh water for great distances during the medieval era. From spectacular suspension bridges to pedestrian walkways, construction of bridges is a challenging process and involves many years of endeavor.
Here is a brief view on the architecture and construction of some of the iconic bridges in the world.
The Golden Gate bridge is certainly the most spectacular bridge in California. It is one of the world’s longest to spanning 4200 feet. It is constructed with earthquake-resistant technology. This bridge has walkways, bicycling lanes, and a six-vehicle traffic lane. Eco-friendly cement is often used for the construction of sustainable buildings and bridges. The best cement for construction of a bridge is Grade 53 cement, due to its strength and durability.
MP Birla manufactures the best cement in India, in OPC, PPC and PSC categories. OPC is used for the construction of bridges. However, a blended mix of slag cement might be used in certain areas exposed to water. Ponte Vecchio in Florence, Italy is a classic example of renaissance infrastructure. It is a one-of-a-kind bridge spanning over the Arno river. This bridge had medieval century workshops and houses on the top of the structure. Now a major tourist destination in Florence, this bridge has a history of surviving through World War II.
The stunning Brooklyn Bridge across the New York City Skyline spans at a length of 1596 feet over the East River. It features a great pedestrian walkway for the walkers and the cyclists above the automobile lanes. The construction of this bridge was carried on fourteen years. Akashi Kaiko is the longest suspension bridge, located in Japan. It is also the tallest bridge in the World. It connects the city of Kobe with Iwaya. It spans a length of 3911m. This bridge is made of steel.
Irrespective of the construction material of cement or steel, understanding the construction techniques of bridges gives us an insight into the most marvelous structures of the world. It helps us to appreciate the endeavor of talented architects and designers. The design of bridges can also serve as an inspiration to modern construction work.
