Another $15 million in federal funding has been awarded to the state for ongoing upgrades to BWI Thurgood Marshall Airport's runways, legislators announced Tuesday.

The Airport Improvement Program funding, won by the Maryland Department of Transportation and the Maryland Aviation Administration, follows an initial $5.7 million the airport has already received and further chips away at the overall $44 million cost of the project, aimed at improving traffic flow of taxiing aircraft.

"Maryland jobs and billions in revenue for our state depend on maintaining BWI Marshall as a safe, dependable and efficient hub for domestic and international travel," said U.S. Sen. Ben Cardin, a member of the Senate's transportation and infrastructure subcommittee, in a statement applauding the award. "Continued federal investment in BWI Marshall reflects our commitment to maintaining safety and the health of our regional economy."

"It means jobs today to construct the improvements to BWI's runway infrastructure," said U.S. Sen. Barbara Mikulski, chair of the Senate appropriations committee, in her own statement. "And it means jobs tomorrow by ensuring that BWI remains a safe, efficient travel center and an economic engine for Maryland."

The project will help bring BWI's aging runways into Federal Aviation Administration safety and design standards, in part by shifting one of the airport's taxiways to increase the open space between it and others.

The project will "complement" another, $350 million runway enhancement project that is also under way, officials said.
