In today’s societies, the semantic vacuum in urban spaces and the overwhelming attention to cavalry and mere use have reduced the position and concept of bridge architecture — especially in linear urban spaces.

Therefore, in addition to paying attention to the structural structure of the new bridges, attention should be paid to the meaningful elements in their architecture, in order to persevere with vitality in explaining the nature-oriented approach.

In this regard, one of the characteristics of assessing urban spaces is quality, a sense of belonging to a place that by creating meaning leads to the formation of spatial identity.

Such spaces are valued and differentiated by communicating with the audience as places for the constant return of the people to them.

Hence, by modeling the Khaju Bridge On the Zayandeh River in the city of Isfahan, as a successful example in creating a sense of belonging to the place and Vitality and communicating with people over time, and modeling the Nature bridge as a bridge that has been able to improve the quality of communication and social interactions and the provision of human beings, and among the amusement spaces of two Water and Fire, and Taleqani Parks and above the Modarres Highway that one of the large highways of Tehran, creates an environment that show people tend to spend more time on Herrera from the bridge.

The similarity between the two bridges is as follows: The nature bridge is designed for walking. Pedestrian traffic is on the two floors and we are witnessing the movement and stay on this bridge because of the oval stations that are installed on the bridge and above the bridge there is a flow of cars that have a sensation similar to the Khaju Bridge, while observing Water flows from below the bridge.

The Khaju Bridge, built in 1650, and the Nature Bridge built in 2014 are presented as two 3D models by our team.

Khaju Bridge is one of the most famous, oldest and finest of Iranian bridges in Isfahan. It was built by the Persian Safavid king, Shah Abbas II, around 1650 AC on the foundations of an older bridge. Serving as both a bridge, and a dam (or a weir), it links the Khaju quarter on the north bank with the Zoroastrian quarter across the Zayandeh River.

Khaju is one of the bridges that regulate the water flow in the river because there are sluice gates under the archways over the river. When the sluice gates are closed, the water level behind the bridge is raised to facilitate the irrigation of the many gardens along the river upstream of this bridge.

On the upper level of the bridge, the main central aisle was utilized by horses and carts and the vaulted paths on either side by pedestrians.

Octagonal pavilions in the center of the bridge on both the down and the upstream sides provide vantage points for the remarkable views.

The lower level of the bridge may be accessed by pedestrians and remains a popular shady place for relaxing.

This bridge is one of the finest examples of Persian architecture at the height of Safavid cultural influence in Iran.

In words of Upham Pope and Jean Chardin, Khaju Bridge is «the culminating monument of Persian bridge architecture and one of the most interesting bridges extant…where the whole has rhythm and dignity and combines in the happiest consistency, utility, beauty, and recreation.»

Khaju Bridge was named as world’s ‘multifunctional bridge’ in 2008. It also joined the list of most amazing bridges of world in the same years.

Khaju Bridge, except for the goal of crossing the bridge,

There are spaces that encourage pedestrians to stand up and watch the Zayandeh River.

There is also a platform and edges that encourage the person to sit and stop.

In the lower part of this bridge,

There are stone columns in the direction of the flow of water with sharp edges to slow down the water and prevent damage to the bridge

 In the other direction, there are stone steps for the flow of water, which provides a good space to sit and enjoy the flow of water.

The materials used are bricks and tiles, which were used as materials for the famous buildings of that time, such as Sheikh Lotfollah Mosque and …

Architectural design and construction of this bridge took place in the fall of 2009 through the fall of 2010 by Iranian architect Leila Araghian. It was built in the 4 years from autumn 2010 to autumn 2014.

Nature Bridge won the Aga Khan Award for Architectureof 2016, and won the prize in the Highways & Bridges category of Architizer’s 2015 A+ Awards.

Tabiat Bridge is the largest pedestrian bridge built so far in Iran.

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.

The nature bridge like the Khaju Bridge has spaces to stand and enjoy the view that is made in 2 floors.

Moving cars on the Modarres Highway below the nature bridge is similar to the flow of river water at Khaju Bridge.
