Baltimore-Washington International (BWI) Thurgood Marshall Airport in the US is to undergo a $100m renovation project to transform its central section.

The project will widen the checkpoint to help relieve congestion so that passengers will be able to move among concourses A, B and C without having to pass through security for a second time.
