"Tabiat" Bridge


Moddares Highway by the end of spring 2013

Tabiat” bridge, linking Ab-o-Atash and Taleghani parks, has a unique structure, designed by Leila Araghian. This bridge has earned a lot of credits for Diba Tensile Architecture so far. 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.
Tehran has grown to a metropolitan city which its traffic jams, busy streets and endless hours wasted in commuting can frustrate the residents and they miss the beautiful view of snow capped Alborz mountain range located in the north of the city. Tabiat bridge gives Tehrani people an opportunity to shake away their stress and exhaustion by just lingering their walk on the bridge and enjoy the marvelous view of whole Tehran.


In the preliminary design, the bridge consists of a main body that crosses over Moddares highway. there are several walkways spreading through Talegani park that have access to the bridge. The curved body of the bridge in different heights, gives visitors countless views and perspectives. 

 


3 Levels of the Bridge

As said above, this iconic pedestrian bridge is designed in 3 levels. The first level has a café gallery and a coffee shop. 



The second level is mainly  designed for people who are crossing from one park to the other, they maybe walking, biking ,skating or riding on a horse carriage.




Finally, level three, or the stay zone, is a place to stay and sightsee. In the middle of the bridge there are stairs and ramps  designed  to get from one level to another. The ramps make all the levels of the bridge accessible for wheelchairs.





Structural Analysis And Engineering

"Tabiat" bridge is a very complex structure. the tree-like columns and unsymmetrical curved body of the bridge made the engineering calculations even more complicated for Massimo Maffeis engineering team,  but all in all a massive steel structure held by only 3 columns can take anyone's breath away.

At the moment only the main body of Tabiat bridge is under construction and will be completed by the end of June 2013.

 The award-wining design

In spring 2009 “Nosazi AbbasAbad” Company held a competition to design a pedestrian bridge, but not an ordinary one; they wanted a special bridge, “a place to stay”. In the first round only the concepts of the design were formed which are shown in the picture below. Leila Araghian’s design was one of the four best designs.



 

The second round was mostly focused on the actual design, considering the budget and timing of the project. The holders of the competition wanted the bridge to become one of Tehran’s landmarks. At this point the preliminary design changed into a complex and dynamic form, yet keeping the initial concepts of the design. The final design was the winner of the competition.
Finalaizing the design was a parallel work between architects and engineers which took about one year and the construction started in fall 2010.
