The Helix Bridge in Singapore is the world's first double helix pedestrian bridge and was completed on April 24, 2010. On that night, people flocked to the heart of Singapore to attend the grand opening ceremony of this landmark footbridge. The Helix Bridge has become a landmark in Singapore, located nearby the Marina Bay Sands.
The Helix Bridge itself is a development goal in the Marina Bay area. The Bridge runs parallel to the Marina Bay Highway Bridge, connecting the Marina Bay center with the South Marina Bay area, forming a large-scale development that integrates top-level landscapes with a business and financial center.
The Helix Bridge is a pedestrian walkway constructed of stainless steel with two spiral structures that wrap around opposite directions. Its design is inspired by the spiral geometric arrangement of DNA, reflecting the meaning of life continuation and renewal, and growth. Let's learn more about the actual size of the Helix Bridge in this post.
Description of the Helix Bridge Size
The 280-meter-long pedestrian bridge, the world's first double-helix Bridge, connects central Marina Bay and a large casino/hotel resort. It is a very lightweight bridge constructed almost entirely of duplex stainless steel. The outer helix is formed from six tubes; the inner helix consists of five tubes, both 273 mm in diameter. The double helix's inner helix supports the shaded perforated glass and stainless steel mesh canopy. Duplex stainless steel has many advantages: this highly corrosion-resistant duplex stainless steel ensures low maintenance and aesthetic durability over its bridge design life of at least 100 years in Singapore's hot and humid marine climate.
The Bridge will also connect Marina South and Marina Central, forming a 3.5-kilometer pedestrian loop around Marina Bay. The first local Art Park was located near the entrance of the Helix Bridge; some other facilities were opened simultaneously. There are five circular viewing platforms on the Bridge where pedestrians can rest or overlook the city, and it is also the best place to watch water sports and fireworks.
The Helix Bridge Size
The Helix bridge is constructed of two spiral curves made of stainless steel pipes that are intertwined and spiral to form a core structure that is 280 meters long. It is 6 meters wide and can accommodate 16,000 people simultaneously. The 280 m Bridge comprises three 65 m spans and two 45 m end spans. The adjacent motor bridge is 303 meters long and nearly 40 meters wide, with three two-way lanes. The Bridge weighs around 1700 tonnes in total.
|Total Length||280 m (920 ft)|
|Max. Capacity||16,000 people|
|Weight||around 1700 tonnes|
|Longest Span||65 m|
Whether viewed from the bridge deck or the viewing platform, the Helix Bridge makes the city's skyline even more spectacular. The stainless steel surfaces render brilliant night lighting effects, as they reflect the light of special lamps built into the bridge to enhance the aesthetics of the design. Each viewing platform is the best spot for tourists to take photos with the great night view of Marina Bay. Walking on this bridge with changing lights, you can appreciate the architecture that combines art and practicality, experience the creative urban construction of Singapore, and feel the endless energy of life.
