Work progresses on the $5.4-million, 20,000-square-foot hangar project at the Bartlesville Municipal Airport. Koehn Construction crews were working on structural steel erection this week on the site. The airport received more than $2.38 million from the Oklahoma Aerospace and Aeronautics Commission to help fund the construction of the hangar and the adjacent apron/taxilane pavement, with the remaining $3.02 million funded by the Bartlesville Development Authority. The project is expected to be complete by fall of 2026.
