The last leg of the 701-km Samruddhi Mahamarg was inaugurated at Igatpuri by Chief Minister Devendra Fadnavis and his deputies Ajit Pawar and Eknath Shinde on Thursday afternoon.

Describing the project as an engineering marvel, Fadnavis said by connecting the expressway with the proposed Vadhvan port, the state government is planning to develop it as an “economic corridor”.

A smart integrated traffic management system will be installed on the expressway soon, the chief minister said, adding they have given the ‘right of way’ to the Gas Authority of India Limited for laying the pipeline while making the access control road between Mumbai and Nagpur.
