Officials said that the bridge, connecting Mazgaon and Umerkahdi areas, would be completed in 19 months and would cost Rs 52 crores to build.
Hancock bridge, over 136 years old, was dismantled in November 2016 because its low height was creating problems during the conversion of Central Railway's electric traction from Direct Current to Alternating Current, said officials.
Speaking about the new bridge, Chief engineer (bridges) Shitalaprasad Kori told PTI that it would be longer and wider than the dismantled one.
Mumbai Mayor Vishwanath Mahadeshwar today laid the foundation for the bridge, which officials said will be constructed by civil engineering firm Sai Projects.
