- Bridge constructed on 18-inch prestressed concrete piles, with over 1,900 linear feet of piling driven to depths up to 60 feet using a 300-ton crane and heavy-impact diesel hammer.
- Structure built with Florida Slab Beams and a cast-in-place reinforced concrete deck containing over 210 cubic yards of Class II concrete topping with shrinkage-reducing admixture.
- Deck and approach slab pours performed at night using a Bid-Well screed system to maintain temperature control and traffic continuity.
- Substructure included cast-in-place concrete bents and reinforced abutments, supported by deep foundations to meet FDOT LRFD standards.
