Stream Enclosure Project
32’ Span x 8’ Rise Arch- Box

An ECO-SPAN® arch box bridge adds a key visual element to a 3-acre park at a corporate campus in Naples, Florida. The company completed a $100 million expansion project at its headquarters with amenities such as an office tower, a 160-room hotel for visiting guests, and a wellness and medical center.

The expansion project also included a pedestrian-friendly, university-style campus with walking and biking paths. A 3-acre park was added with a 1,000 square foot pavilion for outdoor events. The precast arch box bridge formed a stream enclosure that was built to convey water under the new park, which includes basketball courts, tennis courts, and open space.
