In Mangalore, a five-year-old proposal to widen the 90-km stretch from Mulki to Thokkottu via Kateel, Bajpe, Polali, BC Road and Mudipu has been revived. According to a top official of the National Highways Authority of India (NHAI), this proposal is now before the Authority for preparing a feasibility report.    NHAI said that the proposal came up for discussion at a meeting chaired by Union Minister for Transport and Highways Oscar Fernandes in Bangalore about two months ago. The minister instructed to appoint a consultant to prepare a feasibility report of the project aimed at making the stretch a four-lane road and the NHAI is looking into it.    The stretch, which starts at Mulki on NH 66 ends on the same highway at Thokkottu, near Ullal. It is aimed at easing the traffic congestion on National Highway 66, between Mulki and Thokkottu, and on National Highway 75, between Mangalore and BC Road.
