Five-level, 104,980-m² (1.13 million-ft²) convention facility and a later 9,755-m² (105,000-ft²) expansion with a signature glass entry canopy. The original convention center features the first use of specially designed trusses to create a "building-bridge" over a major freeway. The expansion houses space in “bridge structures” that span a city street to the original facility and rests on sliding bearings to isolate forces, thereby eliminating the need for seismically upgrading the original building.
