The Inner Ring Road refers to one of the two main ring roads, the main inner one and an outer one in Delhi, India. The two ring roads have a combined length of 87 km (54 mi). There are two less significant Ring Roads in Delhi apart from the above two, namely the Rural Ring Road, that runs across the rural areas on the fringe of North West Delhi and West Delhi Ring Road, limited only to the West Delhi region. The AIIMS-Naraina stretch is in the process of being made signal-free.
