The airport has two parallel runways (4R-22L and 4L-22R) and a third runway (11-29) that is primarily used for commuter aircraft traffic. Runway 4R-22L is 10,000 feet long by 150 feet wide, and Runway 4L-22R is 11,000 feet long by 150 feet wide. Both runways have displaced thresholds to reduce community noise impacts. Visual aids include high-intensity edge lights, LED centerline and touchdown zone lighting, and high-speed exit taxiway centerline lighting. More than 12 miles of 75-foot-wide taxiways link the three runways with the central terminal and cargo areas. A $42 million rehabilitation of Runway 4R-22L was completed in 2012, and a $97 million rehabilitation of Runway 4L-22R, including the construction of multi-entrance and cross taxiways was completed in 2014. Runway 4R-22L changed its approach lighting system to an ALSF-2, and additional high-speeds P2 and P3 were completed in 2013. Runway 22L also was upgraded to a Cat III approach system allowing for landings in poor weather conditions.
