1. Introduction
Depending on the purpose, a bridge can be planned in various shapes. To enable a large amount of transportation, a bridge designer can apply several design considerations to a bridge design. Let’s look at one of them.
A double-layer bridge provides more space through the double-layer girder to transport vehicles, trains, or pedestrians. This type of girder has enough vertical clearance to carry them. Therefore, it could make clearance issues under the bridge, and also it could make aero stability issues. Nevertheless, the double-layer girder can be one of the available options for a bridge in areas where heavy traffic is expected.

Bridges have a strong presence. For example, when we are walking or passing by a bridge, we always say we are crossing the "000 bridge". As soon as you get on the bridge, you no longer simply look ahead but start looking at the incredible scenes surrounding the bridge. Besides, most bridges are built with various aesthetic factors, forcing tourists and travelers to take out their cameras and smartphones. Like this, bridges are always in our daily lives and remain in our memories.
We have selected five of the most beautiful "Photo Spot" bridges around the world in this article. The current pandemic situation has made it impossible to travel and see these amazing bridges. That's why we have provided you with some information and some stunning "Photo Spots" where you can take incredible pictures once this pandemic is over.

Background
In 2016, Kolkata witnessed a major steel bridge failure of the Vivekananda Road Flyover during construction which led to 27 deaths and 50 injured. The construction work of a 2.2km flyover began in 2009 and was expected to be completed in 2010. Although six years behind schedule, it was not yet completed the erection part till 2016 (Figure 1).
Geometric Properties of Sections
The geometric properties of sections, which are indicators of the structural performance and load resistance capacity of sections, are characterized by the section shape and dimensions, regardless of material properties. These section properties are needed to calculate the bending/shear stresses, deflections, strength, and buckling, which are essential factors for the overall structural design of bridges.
