The Marriott chain began with two motels in the 1950s. The first opened as a Quality Inn airport motel near Washington D.C. and another motel nearby, the Twin Bridges, a few years later. With the opening of the second motel, Marriott was born as a brand name. The Twin Bridges motel is still operating, but as a full-service hotel. The Twin Bridges property was demolished in 1990, but the Key Bridge property still operates.
