One of the two primary commercial runways at Baltimore-Washington International Marshall Airport is closing next week for runway reconstruction.

The runway will close Monday for the next two months. The repairs are part of a series of improvements BWI is making to its airfield spanning several years, including runway repairs, improving areas surrounding the runways and upgrading navigational tools.

Typically, when both of the commercial runways are in use, one of them is used for arrivals and the other for departures, said BWI spokesman Jonathan Dean.

The runway closure shouldn’t really affect travelers, Dean said. The main exception would be during “poor or extreme weather conditions.” In other words, if there are already delays due to the weather, those could be compounded by having one runway out of service.

The intersection of these runways was reconstructed last September.
