BWI Marshall Airport could be getting a $425 million improvement project, the largest in its history

The state is poised to spend $425 million on an extensive renovation of the busiest parts of BWI Marshall Airport. On Wednesday, the state’s spending board will consider a $332.5 million contract with a Bethesda-based construction firm to advance that massive capital improvement project at the Anne Arundel County airport. The contract with Clark Construction Group is the second construction package for the overall project that would connect the airport’s A and B concourses and improve its luggage handling by creating a new security screening system. It is the largest terminal improvement project in the airport’s history, said Jonathan Dean, a spokesperson for BWI. The project was temporarily placed on hold in April 2020 because of the coronavirus pandemic.
