Dear friends today i am going to discuss about underwater construction so my confusion is how engineers can construct bridges,roads and other underwater construction in big rivers and seas because it is impossible to control water and it is hard to change the direction of water.

On the flat land it is quite easy to build buildings,brides,home, and roads but inside water is hard and life challenging job.

My confusion is how engineer plan to remove water from the site of construction and start building construction on sand.

I salute to those workers who work underground and build such amazing construction and make life easy for travellers.
