Concourse J features a vaulted roof structure, which covers the entire structure and includes a 36-foot cantilevered section at the south end of the concourse, that comprises tapered steel rib members and wide flange beams. Each steel rib has several different radii and no two ribs have the same geometry, which adds to the complexity of the structure.
