The Rithala to Narela corridor of Delhi Metro's Phase IV project is all set to get a spur or branch line extension to connect Holambi Kalan and providing better connectivity to the northwest part of the national capital. The nearly 23-km-long extension of the Red Line (Rithala-Shaheed Sthal New Bus Adda) is going to be the first Metrolite corridor of the capital, with the trains running on a rail-based dedicated corridor on the middle of the road, which will be fenced from both sides. Since this corridor will bring some much-needed public transport connectivity to DDA's Narela sub-city, it has decided to contribute ₹1,000 crore for the development of the project. A joint site inspection has already taken place, informed Anuj Dayal, executive director (corporate communications) at DMRC.
DMRC had suggested that one single alignment cannot serve the entire area with just one corridor. Therefore, in addition to the original corridor already proposed between Rithala and Narela, a spur of 5.6 km length from Puth Khurd to Holambi Kalan is also being planned. This spur from Puth Khurd to Holambi Kalan is suggested to serve the future developments in the area.
