The use of double tees with wide flanges allows the use of fewer beams, which stay in place to form the deck, resulting in a shorter construction time.
The design was called "NEXT D" with an 8-inch (20 cm) flange thickness that does not require deck topping, allowing the wearing surface to be applied directly onto the beams.
