Tucked away in Kasganj district in Uttar Pradesh, the Nadrai Aqueduct has no cement, no steel, and no modern machinery holding it up, yet it has been carrying the Ganga Canal clear over the Kali River since the 19th century, and it's still doing the job today.
There's a bridge in Uttar Pradesh that leaves people scratching their heads the moment they see it. A river flows beneath it. A canal flows on top of it. And it has been doing exactly this, without a single bag of cement or a rod of steel, for well over 130 years. Locals know it by a couple of other names too, "Jhaal Ka Pul" and "Angrezi Pul," or the English Bridge, a nod to the colonial engineers who built it.
