"pass 300,000 people a day" This strikes me as implausible because it implies 208 cars per minute, 24x7
The picture looks like a driveway, and my local interstate has 75K cars/day at 65 MPH and takes 4 lanes and they're pondering making it a 6 lane due to massive congestion due to economic and population growth in the area. I'm looking forward to saving a lot of time after they build the 6 lane.
I would theorize this is merely an on-ramp to a road network that overall passes 300K. It might be adequate for that if its just a few thousand cars per day.
I'm also impressed they can carry 300K people/day on a $2.3M bridge. Not unusual to blow half a billion per mile on a reconstruction project for a large wide interstate in the USA. $2M will get you roughly a small freeway overpass in the USA. The picture in the article looks more like an overpass or onramp than a mainline bridge. A new, long, wide, heavy weight limit mainline bridge over a large river can exceed a quarter billion in the USA. Its possible they're clickbaiting calling a mere onramp a "bridge" as if they're replicating the florida keys LOL.
Traffic in India is a different beast. Your calculation assumes each person is in a separate car, but that is not common. Many people travel on motorcycles or mopeds, often with multiple people on each. Motorized 3-wheel rickshaws are common. There are buses, cars (often with multiple people per car), etc.
