Arch bridge5/21/2023 ![]() ![]() Arch foundations must therefore prevent both vertical settling and horizontal sliding. Described by the Detroit Free Press as melding the city’s passion for football with a love for autos, it was added that “only time will tell what place will take in metro Detroit’s Gallery of Public Art. The arch bridge carries loads primarily by compression, which exerts on the foundation both vertical and horizontal forces. Hailed as one of the world’s most innovative structures when it was constructed, the I-94 Gateway Arch Bridge received several national awards acknowledging its innovative approach to solving redundancy issues that are common with tied arches and the soil requirements of a true arch. The Ponte Vecchio ('Old Bridge', Italian pronunciation: ponte vkkjo) is a medieval stone closed-spandrel segmental arch bridge over the Arno River, in Florence, Italy. The air sealed within the ribs is dry, which helps to prevent moisture that could lead to corrosion. A network bridge is a virtual network device that forwards packets between two or more network segments. Arch: The arch is the arrangement of stone which transfers its own weight and any weight above it down to the abutments upon which it rests. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. Safety and ease of maintenance were also key to the design the bridge’s arch ribs are sealed and pressurized to maintain constant deflection and allow for easy inspection access with minimal traffic disruption. Arch bridges are used for long-span bridges after suspension and cable-stayed bridges. An arch bridge is a bridge with abutments at each end shaped as a curved arch. Below ground, the structure’s longitudinal ties compensate for unstable soils which would have rendered a true arch design impossible. The bridge’s design is an innovative blend of form and function-from the roadway, the structure maintains the sleek appearance of a true arch bridge, further enhanced by pressurized arch ribs resembling footballs. ![]() ![]() Constructed as part of a larger I-94 reconstruction project in anticipation of Super Bowl XL, the Gateway Arch Bridge is a signature modified tied arch structure carrying six lanes of traffic just outside of Detroit. ![]()
