架构师提供的文本描述。塔比亚特桥是伊朗迄今为止建造的最大的人行桥。位于德黑兰北部，连接两个公共公园，跨越沙希德莫达雷斯，城市的主要高速公路之一。‘Tabiat’在波斯语中的意思是‘自然’。

Text description provided by the architects. Tabiat Bridge is the largest pedestrian bridge built so far in Iran. Located in north of Tehran, it connects two public parks by spanning over Shahid Modarres, one of the major highways of the city. ‘Tabiat’ means ‘Nature’ in Persian language.

这座桥长约270米，由一个三维桁架组成，它有两个连续的水平，位于三个树形柱上。主列之上有两个平台，形成第三级观点。所有的层次通过楼梯和多个坡道相互连接，提供了从每一层到另一层的多条路径。尽管桥梁通常被认为是结构项目，但这里的方法更多的是建筑。

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.

这座桥是根据五个主要建筑设计的：

The bridge was designed based on 5 main premises:

不是把一个公园的一个点连接到另一个点，而是把一个公园的多个点和另一个公园的多个点连接起来。这座桥在西面入口处延伸到60米，在公园的同一层形成一个广场；这使得人们很难辨认出公园的尽头和桥的起点。两边和两层入口都有多条通道，将大桥与两个公园的其他重要点连接起来。

1-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. There are multiple paths on both sides and both levels entrances that connect the bridge to other important points of both parks.

桥不仅是一条过路，也是一个停留的地方。桥下有一家咖啡厅和一家餐厅。此外，各层都设有多个长凳及其他座位区，使用者可以在桥上停留多久，便可欣赏到其他地方看不到的景色。

2-Bridge is not only a path to pass but a place to stay. There is a café-Gallery and a restaurant in the lower level of the bridge. In addition to this there are many benches and other seating areas in all levels which make it possible for the users to stay on the bridge for as long as they want to, and enjoy the scenery which they cannot see from any other place.

3.为了避免一个更多的前进命令的观点，这座桥的曲线图、宽度的变化和地板的轻微斜率减缓了使用者的速度，提供了一种漫游的感觉，并使用者的视线不断地转向公园、城市景观和山脉。

3- To avoid a one point perspective which more commands for moving forward, this bridge by its curvilinear plan, changes in widths and the slight slope of the floors slows down the user, offers a sense of wander and constantly shifts views of users towards the parks, cityscape and mountains.

4.由于双方都有如此多的树木，因此选择了树木最少的地点来确定柱子的位置，以尽量减少对现有树木的影响。

4-Since both sides had so many trees, locations with minimum number of trees was selected for locating the columns in order to minimize the impact on the existing trees.

5.由于结构的深度足以使其成为一个建筑空间，它是一个三维桁架，即结构本身，同时也提供了一个建筑空间。这提供了较低的水平，这是覆盖和使桥梁可用在雨天和极端阳光条件下，变化的宽度和高度的桁架提供了双曲的动力形式。

5-Having the depth of structure large enough to make it as an architectural space, It is a 3 dimensional truss that is the structure itself at the same time provides an architectural space. This provides the lower level which is covered and makes the bridge usable in both rainy and extremely sunny conditions, changes in the width and height of the truss provides a double curved dynamic form.

该桥梁的建筑和结构设计发生在2009年秋季至2010年秋季，建筑和结构小组之间进行了非常密切的合作，并于2010年秋季至2014年秋季的4年内建造。它于2014年10月落成，成为德黑兰的第三个象征。

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.
