Living bridge?

This northeastern indian bridge is said to be one of the most strongest bridge ever created. the bridge can carry 50 person crossing at the same time.

What makes this bridge differ from the rest is that it is made up of living tree roots. thus, making the bridge stronger.
The planning of the bridge merely took the locals 10-15 years.They require the harvesting of a few betel nuts to create and the credit for their development goes to a tribe in the hilly Khasi and Jaintia region of India, which is considered one of the wettest places on Earth.
“The War-Khasis, a tribe in Meghalaya, long ago noticed this tree and saw in its powerful roots an opportunity to easily cross the area’s many rivers. Now, whenever and wherever the need arises, they simply grow their bridges,” claims the Atlas Obscura.
The Khasis had their own root-guidance system, which they developed by slicing the betel nut trunks down the middle and hollowing them. This would force the thin, amenable roots of the rubber tree to grow straight out. When they reached the other side of the river, they would take root in the soil of the bank. The living bridge over time was thus created.
