While the first phase of the Samruddhi Mahamarg, from Nagpur to Shirdi, has been thrown open for the public, work on the project's 13.1-km-long package 14—which comprises India's widest road tunnels—is also nearing completion.

Each of the two tunnels, which pass through Igatpuri’s Kasara ghat section, is 7.78 km long and 17.6 metres wide and comprises three lanes in both directions. They are the longest tunnels in the state. The crucial package, which also comprises two viaducts, an interchange, a toll plaza, multiple cross passages and box culverts, will connect Pimpri Saroddin and Vashala Budruk.
