A $20 million grant from the Federal Aviation Administration will be used for improvements at Bradley International Airport in Windsor Locks, Gov. Ned Lamont and members of Connecticut’s federal legislative delegation said Friday. Money from the FAA’s airport terminals program will be used to increase the capacity of Bradley International’s ticket counter area as well as improving baggage handling at the airport. The federal money is a small piece of the $185 million price tag for the project, most of which will come from bonding, said Kevin Dillon, executive director of the Connecticut Airport Authority, which oversees Bradley’s operations. The FAA’s terminals program is funded through the Infrastructure Investment and Jobs Act, with $5 billion in grants available to address aging infrastructure of the nation’s airports. The work at Bradley is expected to create 2,500 jobs during the construction process.
