Delhi Metro announced the completion of two tunnels on the Janakpuri (West)-Botanical Garden corridor. Two parallel tunnels at Dabri Mor were completed with the help of two tunnel boring machines (TBM). The two TBMs - named 'Rid-dhi' and 'Siddhi' - emerged at the Dabri Mor station after boring the two 1.2-km- (0.7-mile-) long twin tunnels. While one of the TBMs was inserted in December last year, the other TBM had started work in January. These are the first tunnels to be completed on this corridor, the Times of India reported.
