The 2,000-Ton Structure for the three-level pedestrian bridge been completed in less than two years. The design of this three-level pedestrian bridge is inspired by ancient Iranian architecture in which, bridge was not just a crossing path, linking 2 sides of a river or valley, but It was a place to stay, relax and enjoy beautiful views
The architectural and structural design of the bridge happened from fall 2009 to fall 2010 by a very close collaboration between architectural and structural teams, and was constructed in 4 years from fall 2010 to fall 2014. It was inaugurated in October 2014 as the third symbol of Tehran
Construction of the bridge started in 2010, using a total of 2000 tonnes of steel and 10000 cubic metres of concrete before it was finished in October 2014. Construction of the bridge over a large highway was described as a big challenge, with platforms and temporary tunnels built to ensure that nothing fell on to the road below.
Instead of connecting one point on one park to one point on the other, the design was to connect multiple points on one park to multiple points on the other. The bridge widens to 60 meters on its west entrance and forms a plaza on the same level of the park; this makes it difficult to recognize where the park ends and the bridge starts
The bridge is about 270 meters long and consists of a 3 dimensional truss with two continuous levels that sits on three tree shape columns. There are two platforms on top of the main columns forming the 3rd level viewpoints. All the levels are connected to each other by stairs and multiple ramps, providing multiple paths throughout the bridge to get from each level to another. Even though the bridges are usually considered as structural projects, here the approach is more architectural
