MMRDA unveils longest steel deck on Mumbai Trans Harbour Link

02 Nov 2022 CW Team

The Mumbai Metropolitan Region Development Authority (MMRDA) accomplished a significant milestone by successfully launching the longest orthotropic steel deck, weighing as much as six large-sized aircraft, on the Mumbai Trans Harbour Link.

A material is said to be orthotropic if its mechanical or thermal properties are distinct and independent in three mutually perpendicular directions.

What precisely are orthotropic steel decks?
The orthotropic steel deck is a longitudinally stiffened superstructure [part of the bridge that provides the horizontal span] that will carry the vehicular load more efficiently and will improve the bridge's carrying capacity in comparison to the concrete superstructure.

As a result of its lower self-weight than concrete or composite, an orthotropic steel deck superstructure is preferred.
