The longest national highway that crosses Telangana is NH7, which enters the state from its North, starting from Adilabad and going on to Mahbubnagar before exiting the state on its South. Along the way it touches the important districts of Nizamabad, Medak, Rangareddy and Hyderabad, the capital of the state. The Hyderabad city would serve as the joint capital of both Telangana and the rest of Andhra Pradesh for ten years.
