click hereDharwad - Lokapur - Vijayapura Highway KA SH 34 to also on the global standard model, still rail in under consideration between Dharwad and Lokapur. Similar for Bagalkot Kudachi line, KA SH 18 Mudhol - Chikkodi - Nippani is there in parallel. I think SWR is now building new lines in parallel to state and national highways. another example is Davanagere - Tumakuru new line in parallel to Golden Quadrilateral.
