The David L. Lawrence Convention Center (DLLCC) is a 1,500,000-square-foot 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.
