ST. LOUIS — St. Louis Lambert International Airport sold $287 million in bonds earlier this week to finance capital improvements.

Improvements include the design and construction of a new central utility plant, the design and construction of a new de-icing pad and a new airfield maintenance facility, according to the city of St. Louis’ website.

“These funds are a key piece of ensuring that we have infrastructure and facilities that serve STL for years to come,” Airport Director Rhonda Hamm-Niebruegge said.

The proposed funding sources include general Airport Revenue Bonds, FAA Airport Improvement Program grants, passenger facility charges and Airport Development Fund dollars, according to the city’s website.

“Investors continue to show strong interest in St. Louis Airport Revenue Bonds even in a very challenging municipal bond market,” Comptroller Darlene Green said.
