St. Louis Lambert International Airport has received $30 million in federal grant funding toward construction of a new central utility plant (CUP). The CUP is a key component of the airport’s plan to consolidate its two terminals into a single facility and modernize passenger operations.
The facility will house critical infrastructure systems, including power, water, heating and cooling equipment needed to support the future terminal complex.
The grant is the latest in a series of federal investments supporting the airport’s multi-billion-dollar terminal consolidation program, which aims to streamline operations, improve passenger flow and position STL for future growth.
In addition to federal funding, STL’s signatory airlines approved more than $331 million in 2023 for projects tied to the consolidation effort, including the utility plant, a new deicing pad, relocation of airfield maintenance facilities and other supporting infrastructure.
The airport’s approved master plan envisions an updated, consolidated terminal with up to 62 gates, multiple concessions, new roadways and expanded parking facilities designed to accommodate future passenger growth through 2040 and beyond.
Airport officials said the terminal consolidation program is currently at the 30 percent design milestone, with additional reviews at the 60 percent and 90 percent stages ahead before the project moves into procurement and construction.
