  • Extends FLL boundaries by elevating the runway over roadways and a rail line
  • Increases airport capacity by accommodating larger passenger aircraft
  • Helps FLL meet increasing travel demand and enhance the customer experience.

Towering 60-feet in the air at the Ft. Lauderdale-Hollywood International Airport (FLL), a mechanically stabilized mountain supports a pair of massive concrete bridge structures. These structures were designed to safely carry even the world’s largest passenger aircraft over active roadways, including U.S. 1, E. Perimeter Road, and the Florida East Coast Railway. The structures include six parallel tunnels topped with a 500,000 square-foot runway deck capable of handling the rough landing of a fully loaded 747 or Airbus A360. This engineering feat is only the second of its kind in the U.S., following a similar configuration at the world’s busiest airport, Atlanta Hartsfield-Jackson International.

The structures are part of the Broward County Aviation Department’s plan to expand and elevate FLL Runway 9R-27L to an overall length of 8,000 feet—a critical component of the airport’s $791 million improvement program designed to increase airport capacity, enhance the air traffic system, and accommodate larger passenger aircraft for the 23 million passengers it serves annually.

What We Did

With little precedent to follow, Gannett Fleming drew upon our specialized niche expertise to provide geotechnical design engineering and analysis, turnkey intelligent transportation systems (ITS) design and construction services, and construction inspection services for the Runway 9R-27L expansion project.

As the geotechnical engineer of record, we performed standard penetration test and auger borings, as well as geotechnical engineering and design support for the mechanically stabilized earth walls, embankments, roadway, bridge foundations, drilled shaft foundations, water retention areas, and signal poles. Gannett Fleming also designed and implemented ITS at FLL to support traffic management and operations as part of the Runway 9R-27L expansion project. We provided complete design services and technical integration for extensions to two separate ITS subsystems, including the Broward County Aviation Department system, as well as the Florida Department of Transportation’s fiber-optic communication network system.
