Pune-Mumbai Expressway 10-Laning Faces Delay As MSRDC Ordered To Conduct Fresh Surveys Before Expansion. The ₹14,260-crore project to widen the 94.6-km expressway from six to 10 lanes is likely to be delayed after MSRDC was directed to conduct fresh surveys. The additional assessment may push back approvals and construction, despite rising traffic pressure on the Mumbai–Pune corridor.
