MANGALURU: Union Minister for Road Transport and Highways Nitin Gadkari on Thursday told the Lok Sabha that the proposed green tunnel bypass through Shiradi Ghat on Bengaluru-Mangaluru National Highway 75 is not viable, and instead, he has asked the National Highways Authority of India (NHAI) to prepare a detailed project report (DPR) for a four-lane road on the 26-km ghat stretch.
