In a bid to ensure better connectivity, with the proposed international airport at Navi Mumbai and the growth centers in Raigad district, the state government is planning a monorail route on the Mumbai Trans Harbor Link (MTHL). Work on the 22-kilometer long MTHL, which will connect Sewri in mainland Mumbai to Nhava across the creek, is due to begin on January 26 next year, and senior state government officials said that a lot of thought is being given on whether the civil structure for a monorail route could be incorporated in the design of the bridge. The Mumbai Metropolitan Region Development Authority (MMRDA) has already set in motion the process for the first monorail service between Jacob Circle in Central Mumbai to Wadala and from there to Chembur in the eastern suburbs. Officials said the same route could be extended across the creek from Wadala. They added that there were technical problems in incorporating the design for a metro railway in the Rs 8,000 crore, eight- lane MTHL, as the resonance and vibrations caused by the comparatively heavier metro were not suitable to the present design of the bridge.
