The airport that traded a 'V' layout for an inverted 'Z'
In short: Jacksonville International Airport is currently undergoing a structural evolution. To solve complex traffic conflicts, planners are moving away from its current 'V' runway pattern toward a geometric 'inverted Z.' This shift highlights the constant tension between historical infrastructure and the demands of modern aviation.
The airport’s layout history is defined by necessity. When Jacksonville International Airport opened on September 1, 1968, it replaced Imeson Field primarily because the terrain at the old site prevented lengthening runways for commercial jets. Early designs even experimented with passenger flow, initially trying to separate arriving and departing passengers on different sides of the terminal—a layout that has since been replaced by a more standard multi-level configuration.
Current expansion is driven by record-breaking growth; in 2019, the airport handled over 7.1 million passengers, and it hit a new record of 7,647,916 in fiscal year 2024. To accommodate this, the Jacksonville Aviation Authority (JAA) is moving toward a master plan introduced in 2020. This plan proposes building an 8,000-foot runway in the southwestern portion of the airport to create an 'inverted Z' layout. This specific geometry allows for simultaneous independent operations on the current northern runway and the future southern runway while eliminating directional conflicts at the tip of the existing 'V' pattern.
The facility also serves as a critical military hub, housing the 125th Fighter Wing. While it lacks the massive infrastructure of major bases, it supports approximately 300 full-time and 1,000 part-time personnel. The airport continues to balance these complex demands—from hosting F-35A Lightning II aircraft to managing high-volume commercial traffic and navigating significant infrastructure repairs, such as a $38 million parking garage reconstruction following a 2025 fire.
