A new stretch of Bengaluru's Namma Metro train service will be inaugurated today, on the occasion of Makara Sankranti, and will be thrown open to the public from Friday. The stretch on Green Line connects the existing Yelachenahalli Metro Station to the Silk Institute Metro Station on Kanakapura Road -- a highway out of Bengaluru. It will be inaugurated by Union Minister Hardeep Singh Puri.
