Seasonal Airfield Construction and Maintenance at MSP

The airfield at Minneapolis-St. Paul International Airport (MSP) is one of the busiest in the United States. Maintaining airfield features (i.e. runways, taxiways, aircraft parking surfaces, etc.) requires coordination of regularly-scheduled construction and/or maintenance tasks that involve pavement, painting, electrical work, signage, navigational aids, and area protection barriers. Most often these activities will occur during the nighttime hours because the lull in aircraft and passenger activity offers safer conditions for construction workers and reduced impact on scheduled operations. Major construction and maintenance projects are conducted during spring, summer, and autumn when the earth is not frozen.

People residing in areas around MSP may notice unusual sounds, lights, or aircraft activity when these construction or maintenance activities are occurring.

A joint sealing project will be conducted on Runway 12R-30L from May 12 to 29. This runway will be closed from 11 p.m. to 5:30 a.m. After this project is completed, nighttime operations will be back to “normal.”

It is important to note that airfield construction and/or maintenance may require closing one or more runways at MSP temporarily, even when the activity is not occurring on the runway itself because the area around a runway is just as protected as the runway surface for safety reasons.

Even temporary runway closures impact how aircraft operate into and out of MSP. When one or more of the runways are closed, the arrivals and/or departures that would normally use that runway will be directed by air traffic control to use an open runway, inevitably changing where aircraft are flying in the sky.
