The Gateway Sports and Entertainment Complex is an entertainment complex located in downtown Cleveland, Ohio. It opened in 1994 and is owned by the city of Cleveland and Cuyahoga County and is managed by the Gateway Economic Development Corporation, a non-profit group with board members who are appointed by county and city leaders. The complex mainly consists of Progressive Field, a 34,830-seat baseball park that serves as home of the Cleveland Guardians of Major League Baseball, and Rocket Mortgage FieldHouse, a 19,432-seat arena primarily the home of the Cleveland Cavaliers of the National Basketball Association. In addition, the complex includes a transitional space known as Gateway Plaza and the Gateway East parking garage. Gateway is roughly bounded by East 9th Street to the east, Huron Road to the north, Ontario Street to the west, and Carnegie Avenue to the south, and forms the basis of the larger Gateway District of downtown Cleveland. The two facilities are connected to Tower City Center and the RTA Rapid Transit system via an underground walkway. Facilities Progressive Field was completed first, opening on April 4, 1994, as Jacobs Field. It cost approximately $175 million to build, of which $91 million, or 52%, came from Indians owner Richard Jacobs. The remaining $84 million, or 48%, was from a 15-year sin tax. It was designed by HOK Sport (now known as Populous), a division of Hellmuth, Obata and Kassabaum. HOK designed it as a retro-modern ballpark, similar to their just-completed Oriole Park at Camden Yards in Baltimore, with asymmetrical fences of varying heights, a smaller upper deck, and stepped tiers. The ballpark was situated in a way that would showcase Cleveland's downtown skyline. Rocket Mortgage FieldHouse, originally named Gund Arena and later known as Quicken Loans Arena, has dimensions of long by wide by high (). It was designed by Ellerbe Becket Sports & Venue and Robert P. Madison International Inc., a local architectural firm. Similar to the ballpark's downtown views, the arena has a by bay window that faces southeast and shows off the city's industrial Flats. The construction and engineering were completed by an integrated team from Ellerbe Becket. The underground service area can accommodate 26 tour buses. It was built for approximately $152 million and opened on October 17, 1994. Gateway Plaza is multifunctional open space situated between Rocket Mortgage FieldHouse to the north, Ontario Street to the west, Gateway East parking garage
