During the 1990s, the Noida extension (now a part of Gautam Buddh Nagar) became what is today known as Greater Noida. The Greater NOIDA Authority manages the development of the city. Greater Noida is connected to Agra by the six-lane Yamuna Expressway. The annual Indian Grand Prix is held at the Buddh International Circuit. Roads are wide with service lanes for every major road. The sectors are named by letters of the Greek alphabet. All cabling and utilities have been built underground. Alpha, Beta, and Gamma are the oldest sectors. The other emerging sectors include Xu, Delta, Mu, Omicron and Tau. The present GNIDA office is in Gamma  II sector just opposite the historical village Rampur Jagir/Jahangir where the revolutionary Pandit Ram Prasad Bismil lived in 1919 when he was hidden underground after the Mainpuri conspiracy. A park has been named "Amar Shaheed Pt. Ram Prasad Bismil Udyan" by the Uttar Pradesh Government.
