Hartsfield-Jackson International Airport is raising $474 million in bond financing for capital improvements.

The airport plans to use the bond financing for future terminal and concourse improvements, including an expansion of the Concourse C midpoint and upgrades to aging escalators and elevators. It is also using the bond funding to replacing short-term commercial financing. The interest rates on the bonds are "some of the best rates we've gotten in a long time," said airport general manager Louis Miller. Issuing the bonds costs the city about $4.3 million.

The Atlanta city council voted at a special meeting Wednesday to approved the bond deal, which is set to close May 3.
