<p>The Mumbai Metropolitan Region Development Authority (MMRDA) on Monday successfully launched the longest Orthotropic Steel Deck (OSD) at the under-construction Mumbai Trans-Harbour Link (MTHL).</p>.<p>Weighing around five to six Boeing aircraft, this OSD is the 14th of 32 OSDs to be erected within the project. It is also the longest one.</p>.<p>The first OSD was launched on April 1, 2022.</p>.<p>The OSD is a steel deck superstructure strengthened or stiffened both transversely and longitudinally which will carry the vehicular load more efficiently among three planes and improve the load-carrying capacity of the bridge as compared to the concrete superstructure for a similar span. OSD Steel Deck Superstructure has lesser self-weight than concrete or composite.</p>.<p>Speaking at the launch, MMRDA Metropolitan Commissioner S V R Srinivas, said, “It is a significant milestone that team MMRDA has reached in MTHL. Teams are moving in sync with our catchup plan towards commissioning the project by next year-end."</p>.<p>The 22-km-long cable-stayed bridge would be similar to the Hangzhou Bay Bridge in China (36 km) and King Fahd Causeway in Saudi Arabia (26 km). </p>.<p>The MTHL would connect Sewri in Mumbai with Nhava-Sheva across the harbour.<br /> </p>
