Jinnah Avenue is an important road located in Blue Area, the main business district of Islamabad. The Blue Area is the commercial and business hub of Islamabad, Pakistan. It is called the "Blue Area", because it was represented in blue color in the original design (master plan) of the planned city. The area is actually a corridor that runs along Islamabad's Khayaban-e-Quaid-e-Azam (also known as Jinnah Avenue), Islamabad's primary arterial road which leads up to the main government buildings. It is characterized by clean, wide roads and tall buildings among the panoramic greenery of the adjacent areas. It is limited by Nazimuddin Road to the northwest and A. K Fazl-ul-Haq Road to the southeast and Ibn-e-sina road to the south west.
