The movement of tides is an important factor in the construction of the 5th and 6th lines between Diva and Thane, as the work enters a crucial phase. Truck movement to build the bridge can only be done during low tide, and this affects work.

"The railway project involves building a bridge on the creek at Mumbra on the south side of the station. The water levels vary as per tide, so engineers need to be very careful when and how to continue work, and allow truck movement for moving debris etc. Firstly, the soil is soft and it leads to sinking, and secondly if a truck enters at the time of high tide, it could sink. A truck had sunk in October 2018," a senior railway official said. The Mumbai Railway Vikas Corporation is building the line.
