Originally a tiny layout built by Bangalore Development Authority (BDA) in the 1970s and was surrounded by villages like Gangenhalli on the west, the military campus on the east, Matadahalli by south and parts of Hebbal village by north. Close proximity to other high-profile areas like Sadashivnagar and Dollar's colony (SanjayNagar) led to rapid development of RT Nagar. Also setting up of a Head post office on RT Nagar main road provided further impetus to the growth of RT Nagar. It is a posh area in Bangalore.
Over the last few years RT Nagar has come to commonly represent many areas like MLA Layout, Gangenhalli (Ganganagar), Dinnur, SultanPalya, Kanakanagar, Manoranpalya and even Kavalabyrasandra simply because these areas fall under the RT Nagar head post office (with Pin code 560032) jurisdiction. Even today many businesses in these areas actually show "RT Nagar post" as an address line item.
Major commercials hubs for businesses in RT Nagar are the RT Nagar Main Road (80 Ft road), Dinnur Main Road, Sultan Palya Main Road and Ganganagar 5th Main (with a sizable number of Marwari shops). Most of the commercial activities of the area are centered on the 80 Ft Main road. There are many more commercial shops in the RT Nagar Main road which includes many food buildings and shopping buildings.
