For more than 160 years, just two railway tracks have connected Mumbai to the rest of India along Western Railway’s northern corridor. Now, this longstanding bottleneck is finally being addressed, with new bridges across the tidal Vaitarna River set to more than double the corridor’s track capacity.

In a major milestone for the Virar-Dahanu quadrupling project, the challenging South Vaitarna bridge has been completed, while its northern counterpart is nearing completion, bringing the expansion of Mumbai’s suburban railway network closer to reality.
