In mid-1997, the airport's name was changed to Bristol International Airport. In November 1997, the successful bidder for the purchase of a 51% stake in the airport company was revealed to be FirstBus. The remaining 49% was retained by the council. Work on the new terminal building had already started; it opened in March 2000, at a cost of £27M. In 2000, passenger numbers exceeded two million for the first time. A new control tower was built and the A38 road was diverted to cater for the installation of a Category 3 instrument landing system; these projects were completed in 2001.
