The Mumbai Trans Harbour Link is a 6-lane road bridge across the Mumbai Bay between Sewri in Mumbai and Chirle in Navi Mumbai. When completed, it would be the longest sea bridge in India. MTHL is divided into three construction packages for execution, in which package 1 comprises 10.38 km of bridge section spanning across the Mumbai Bay and Sewri Interchange. The total bridge is of about 22 km length which comprises 16.5 km of sea bridge and 5.5 km of viaducts on land on both ends of the bridge, the MMRDA further said.
"Team MMRDA has achieved another milestone by installing the 1st Composite Steel Girder Span out of 5 that will connect MTHL PKG 1 with Eastern freeway.

MTHL is the Engineering Marvel which will decongest Mumbai city and connect it to the mainland," said S.V.R. Srinivas IAS, Metropolitan Commissioner, MMRDA.
