The Gateway project is a sports Mecca situated on a 28-acre site two blocks from the heart of downtown Cleveland. When completed in 1994, $362 million complex will feature a 42,000-seat, natural grass baseball stadium for the Cleveland Indians and a 21,000-seat indoor arena for the Cavaliers basketball team. Construction began in January 1992. More than 7,500 pieces of precast concrete and 55,000 cubic yards of ready mixed concrete were used in the stadium, and 4,000 precast pieces and 19,000 cubic yards of ready mixed concrete were used in the arena.
