<< According to official records, the design for the bridge shifted multiple times over the past seven years, largely due to conflicts between the Public Works Department (PWD) and the Railways. The two agencies couldn’t agree on how to share land, and in trying to work around both railway property and the new Metro line, they ended up producing a final layout with an abrupt 90-degree angle.

I love that mindset. Europeans would have simply refused and 100 years later it would have probably been build after all legal has been cleared. Indians instead never say no. That's how you build software, so why not bridges.

Shouldn't the bureaucracies be penalized, instead of the poor engineers?

The engineers built the 90-degree layout specified by their clients!

I wouldn't be surprised if there's a paper trail documenting the engineers' objections, signed and notarized by the clients.

It's hard for me to judge the engineers without knowing more.

No. I'm a licensed civil engineer in the US. The license comes with an explicit duty to the public, to uphold public safety. I am in responsible charge of the work I produce and personally liable for the safety of that work, in perpetuity, and it SHOULD be that way. Any plans that I produce are subject to that standard.

India has a similar system for public works projects where a licensed engineer MUST supervise the work.

Frankly, sometimes I think the software world would be a lot better off with a similar system.

This doesn't look unsafe though, just inconvenient.

Both in the US[1] and UK[2] you can find bridges with actual 90-degree angles. The one in India[3] is more like 75 degrees.

I am curious, how did you find those?

I like to think that it's (posh accent) "Yes good sir, I do indeed keep an extensive collections of references to exotic bridge layouts"

What would be neatest is to learn that there is an exotic geospatual query language. "no junction and road bend radius less than 20M within 50 meters of bridge"

But I suspect it is a well formulated web search "Complaints about right angle overpass"

And final thoughts, Your right, it is not much different than a common freeway offramp system. So I am not sure what the fuss is about. Perhaps too constrained, and it needs a larger turning area?

in the 90s i built a webinterface for a database of architectural details for a university department. i don't know if it included bridges, but i am sure that some university departments teaching bridge building or traffic planning somewhere have a database of bridge layouts. maybe this one here: https://urbannext.net/
