Work included an expansion of runway 01L/19R, rapid-exit taxiways and parking bays. The runway was extended by (2790 metres to 3190 metres) on the northern side and on the southern side and was fitted with CAT-I facilities for night use. A 119-year-old mosque that lies 30 metres from the runway' northern end prohibits further expansion in this direction. The longer runway, 01R/19L, was upgraded from CAT-I to CAT-II ILS status to allow landings in poor visibility. In August 2014, it was announced that the instrument landing system of the primary runway would be upgraded to CAT-IIIb. This allows flights to operate till visibility drops below 50 metres. The secondary runway would be upgraded to CAT-II. The upgrading work would start from February 2015 and would be completed by the end of 2015.
