Updated 18th October 2025- A general contractor, J.H. Findorff & Son, has been selected to lead the construction, with work split across four bid packages. Site work is slated to begin as early as August 2025, with demolition of the existing concourse starting around September, and the new two-gate international terminal (55,700 sq ft) expected to follow. Funding includes airport revenue plus federal and state grants, and the redevelopment will replace the outdated international arrival facility, bringing arrivals and departures into one integrated space.
Published 16th September 2025- Milwaukee Mitchell International Airport (MKE) and Milwaukee County have broken ground on a $95.2 million redevelopment of Concourse E, a project that will replace the long-shuttered facility with a modern two-gate concourse connected directly to the airport’s main terminal. Construction is expected to begin in late 2025 and wrap up in 2027.
Concourse E originally opened in 1969 but was removed from regular service in 2017 following years of underutilization. International arrivals to Milwaukee have since been processed in the separate International Arrivals Building (IAB), outside the main terminal — a setup that officials acknowledge has long been less than optimal.
A New Gateway for International Arrivals
The new concourse will directly replace the IAB. County and airport authorities indicate that the design will allow airlines to process international and domestic operations at the same gates, removing the current need to tow aircraft between the main terminal and the IAB. The concourse will also nearly triple the hourly number of international passengers that can be processed — from about 140 at the IAB to about 400 in the new building — thanks in part to the addition of two new passenger boarding bridges.
Funding and Economic Impact
Milwaukee County states that the project will be paid for exclusively by airport revenue and bonding, supplemented by $13.5 million in federal funding. The airport does not use property tax dollars to operate or fund itself. County and airport officials also state that the redevelopment will support 200 construction jobs during the build-out phase.
Contracting and Schedule
The county is delivering the project through multiple bid packages, covering demolition, construction of the new concourse, fueling systems, and jet bridges. Procurement documents identify J.H. Findorff & Son as the main construction contractor. The airport schedule anticipates site work to begin in late 2025 with completion in 2027.
Looking Ahead
When finished, the redeveloped Concourse E will restore a great deal of Milwaukee Mitchell’s terminal capacity, modernize the international arrivals experience, and make things more efficient for both passengers and airlines. Airport officials say the project is a major step forward in positioning MKE as a more competitive gateway for the region’s future air service needs. This mirrors large-scale aviation upgrades across the U.S., such as the rehabilitation of Salt Lake City International Airport in Utah, a $4.1 billion initiative designed to enhance efficiency and passenger experience while supporting long-term growth.
With the Concourse E Redevelopment, MKE joins a growing list of major U.S. airports undertaking massive upgrades, including the $3.4 billion New Terminal 1 expansion at San Diego International Airport, which has begun construction on Phase 1B. Another notable example is the rehabilitation of Salt Lake City International Airport in Utah, a $4.1 billion project aimed at improving capacity, efficiency, and overall passenger experience.
