All flyovers in the city have tiny bumps every few metres because engineers who construct these elevated roads put expansion joints in place to connect two girders — leading to the problem. The Eastern Freeway that connects orange gate near P D’Mello Road to Ghatkopar via Chembur, will, however, have no such rickety joints.

Expansion joints are the exact point where two girders of a flyover meet. A few millimetres of space is kept between girders to allow for expansion and contraction as per the changes in temperature. “While constructing the elevated portion of the freeway a lot of attention was given to the expansion joints. We have made sure motorists have a smooth ride while driving on the flyover,” said a senior MMRDA official on condition of anonymity.
