First two images are of current Biggest bridge in the world

**🇨🇳Danyang–Kunshan Grand Bridge (164.8km)**

China took **4 years** (2006-10)

Then comes India 

🇮🇳**Mumbai–Ahmedabad High Speed Rail Corridor ie. Mumbai–Ahmedabad HSR (353km)**

Out of which \~320km**\*\*** of viaduct is already completed 

Which is twice the current record!!

India took **4 years and 4 months**

(Construction of first viaduct was on 25 November 2021)

Reason for such a rapid pace of construction:

Use of 

**Full Span Launching Method (FSLM) (In the image 3/4)**

This significantly reduces the time required to build viaduct 

(40 meter of literal bridge is constructed at a time)

  


**This** results in higher cost of building HSR in india

**🇨🇳China** : Approximately **$17–$21 million per km**.

**🇮🇩Indonesia** : Approximately **$51–$58 million per km**.

**🇺🇸USA** : Approximately **$34–$200+ million per km**.

**🇮🇳India** : Approximately **$42.3 million per km** (based on latest 2026 revised estimates).

  
As the whole construction is on viaducts!





That's still a crazy achievement!
