Temporary runway closures are due to weather, construction, and/or routine maintenance
Runway closures at Minneapolis–Saint Paul International Airport (MSP) are sometimes necessary and can be attributed to a combination of factors, including weather, construction, and routine maintenance.
Weather conditions and heavy traffic can cause runway pavement deterioration. To ensure optimal functionality and safety, regular maintenance procedures such as cleaning, filling, pavement grading, crack sealing, and marking restoration are carried out. During such maintenance work, partial or temporary runway closures are required. Visual indicators, such as markings, are used to inform pilots of runway closures. A lighted runway closure X, made up of four arms with 20 spotlights each, is used to indicate a temporarily closed runway.
Construction activities can also lead to partial runway closures or changes in the runway threshold. In such cases, aircraft may have to utilize alternative take-off and landing areas, and they can only land from the opposing direction. Construction projects can impact the typical runway use patterns and may require temporary runway closures to ensure the safety of construction crews and aircraft.
Minneapolis–Saint Paul International Airport (MSP) has scheduled essential airfield maintenance projects and construction for 2025. These projects will involve temporary runway closures, specifically the south parallel runway (Runways 12R/30L), which will impact flight patterns and noise levels in the surrounding areas. The MAC Community Relations Office will provide updates and information about runway closures lasting 30 minutes or longer.
During the construction period in 2025, Air Traffic Control (ATC) will prioritize runway availability, wind conditions, and operational efficiency to direct aircraft over less-populated residential areas when possible. The Federal Aviation Administration (FAA) will also implement traffic management initiatives to control the flow of aircraft in and out of MSP during the closures, ensuring efficient and safe use of the airport.

Air Traffic Control (ATC) will adjust runway operations to minimise disruption
Minneapolis-St. Paul International Airport (MSP) is not entirely shut down. However, there is currently a Traffic Management Program in place due to runway construction. As a result, Air Traffic Control (ATC) will play a crucial role in adjusting runway operations to minimise disruption and ensure the smooth flow of air traffic.
ATC will implement various strategies to manage the temporary runway closures efficiently. They will utilise the available runways optimally, adjusting taxi routes and take-off/landing patterns as needed. By doing so, ATC can maintain a safe and efficient flow of aircraft, minimising delays caused by the construction work.
During peak hours, when traffic volume is high, ATC may employ tactical procedures such as metered departures or arrival management programmes. These procedures help regulate the flow of aircraft, preventing congestion and reducing the impact of reduced runway capacity. The specific procedures will depend on the prevailing wind directions, available runways, and other operational factors.
ATC will also work closely with pilots and airlines to ensure they are aware of any changes in runway operations. Effective communication is vital to ensuring that all parties are prepared for the adjusted procedures, which may include modified approach paths or departure routes. Additionally, ATC may provide performance-based navigation (PBN) procedures, offering precise, satellite-based guidance to aircraft, further enhancing efficiency and safety during this period of disruption.
To keep travellers, staff, and the community informed, MAC staff will provide regular construction updates through various channels. These include airport newsletters, website updates, MSP Noise Oversight Committee (NOC) meetings, and quarterly listening sessions. By staying informed, all stakeholders can better plan and adapt to the temporary changes in runway operations, helping to minimise disruption and maintain a positive travel experience.
