TYLin was the Structural Engineer of Record for a new taxiway bridge at Tampa International Airport (TPA) in Tampa, Florida.
TYLin provided the structural design, construction plans, and construction administration support for a new taxiway bridge that adds a key connection between TPA’s main runways. The new bridge improves safety and allows planes to navigate the airfield more efficiently.
The bridge includes three spans with an overall width of 217 feet and total span of 228 feet.
The superstructure on the first two spans consists of cast-in-place post-tensioned concrete box girders. Post-tensioning ducts run both transversely and longitudinally along the first two spans. The third span consists of mildly reinforced concrete slab. The substructure is composed of abutments and piers that are supported by drilled shafts.
- The bridge was designed to carry the loads of a Boeing 777-300ER and a Boeing 747-400ER.
- TYLin’s structural design included Mechanically Stabilized Earth (MSE) walls.
