Initially the four runways were to be long and constructed of macadam with asphalt topping, along with the landing mat. On 30 October 1942, Change "G", ordered the runways lengthened to 5000 ft, and to now be constructed of concrete. Each runway was thick and not reinforced. The runways ran northeast to southwest, northwest to southeast, east to west, and north to south. Lights were located every along the length of three runways, with the northwest to southeast runway being spaced at intervals. The ends of the runways were separately marked with two, three, four, and five lights. There was a temporary landing field built for official visits during construction of the base.
