Travelers who pass through Baltimore-Washington International Thurgood Marshall Airport will see some big changes during the next two years.
The airport is beginning a $100 million concourse renovation project. There will be additional and larger security checkpoints. Moving sidewalks will be added as well as new food and retail stores.
The project is expected to be completed in the summer of 2013.
BWI also announced that AirTran will move to the Southwest Airlines terminal on Wednesday to accommodate the companies' recent merger. Delta airlines will take AirTran’s former space.
