The David L. Lawrence Convention Center (DLLCC) is a 1,500,000-square-foot (140,000 m²) convention, conference and exhibition building in downtown Pittsburgh in the U.S. commonwealth of Pennsylvania. It is served by two exits on Interstate 579. The initial David L. Lawrence Convention Center was completed on the site on February 7, 1981, but as part of a renewal plan the new, completely redesigned center was opened in 2003 and funded in conjunction with nearby Heinz Field and PNC Park. It sits on the southern shoreline of the Allegheny River. It is the first LEED-certified convention center in North America and one of the first in the world.
