Mumbai: MMRDA launches two more OSDs on Mumbai Trans-Harbour Link
The Mumbai Metropolitan Regional Development Authority (MMRDA) this week launched a pair of 120-metre-long Orthotropic Steel Decks (OSDs) on the Mumbai Trans-Harbour Link (MTHL), a 22 km-long sea link that will connect south Mumbai with Navi Mumbai.
The OSD is a steel-deck superstructure, which can carry the vehicular load more efficiently and improve the load-carrying capacity of the bridge as compared to a concrete superstructure for a similar span.
The two 120-metre-long OSDs will each weigh 1300MT. Earlier on January 3, the MMRDA had launched a 70-metre-long OSD on Package 2. There will be a total of 70 OSDs on the MTHL.
