MUMBAI, May 12 -- The city's two new road-over-bridges (ROB) over its suburban rail lines, one at Reay Road and the other at Titwala, are expected to be inaugurated by chief minister Devendra Fadnavis on Tuesday. The bridges, constructed by Maharashtra Rail Infrastructure Development Corporation (MRIDC), will boost East-West connectivity in the areas. The Reay Road cable-stayed ROB, built at a cost of Rs.266 crore, will have six lanes. As it links Byculla with Brittania Industries, motorists can save peak-hour commute time by 30 minutes. The Titwala ROB is a four-lane structure spanning 820 meters at the new Titwala Railway Station on the Kalyan Ring Road. Built at a cost of Rs.100 crore, the bridge will significantly reduce congestion on one of the region's busiest corridors. It will improve connectivity between Ambivili and Kalyan via Shree Siddhivinayak Ganesh Mandir. The Titwala ROB will also improve punctuality of suburban train services as it will replace the existing level crossing gates. MRIDC officials said upcoming ROBs at Dadar (Tilak Bridge), Ghatkopar, and Byculla will be completed soon. Shashank Rao...
