The upper level has been planned as a road crossing while the lower deck is intended to carry Metro Line 13, creating an integrated transport corridor. Present arrangements require commuters to travel about thirty nine km and spend ninety minutes on the route between the suburbs, whereas the proposed alignment would cut this to five km and a ten minute drive, substantially reducing travel time.
The scheme is expected to offer relief to the estimated one point eight million (1.8 mn) residents of the Vasai Virar belt and to ease pressure on existing road networks through improved public transport connectivity. The estimated cost stands at Rs 25 billion (Rs 25 bn), reflecting the scale and complexity of a double deck crossing designed to combine urban rail and highway capacity.
Of the five government clearances required for the project, three have already been secured from the Maharashtra Maritime Board, the Inland Waterways Authority of India and the Maharashtra Coastal Zone Management Authority, leaving two approvals outstanding. The revived proposal signals renewed momentum for a scheme that planners say would strengthen suburban integration, improve commuting efficiency and support wider development objectives in the northern reaches of the Mumbai metropolitan region.
