Baltimore-Washington International Thurgood Marshall Airport, handling a record number of passengers, is undergoing a $60 million expansion.

The state of Maryland is investing in the airport to help keep up with the crowds. Maryland Governor Larry Hogan announced the airport’s international Concourse E will expand by 70,000 square feet on three levels, adding six new gates, restrooms and operational support areas as well as renovations to an existing 20,000 square feet. Two of the new gates will be full service, while four will be for arrivals only. Concourse E services airlines including British Airways, Condor, Norwegian and Wow Air.

“BWI continues to set records and this expansion highlights the continued success of our airport, as well as Maryland’s flourishing economy,” said Hogan. “This expansion will create new job opportunities for hardworking Marylanders, while bringing greater ease and efficiency to international travel, tourism and trade.”

The gates are expected to be in operation by the end of summer 2018. This is the international terminal’s second recent expansion project. The first project, completed in November 2016, added a new eight-lane security checkpoint, food, retail outlets, a secure connector between Concourse D and Concourse E and reconfigured airline gates to support added international service. BWI set a record in 2016 with 25.1 million passengers.
