The Inner Harbor is a historic seaport, tourist attraction, and landmark of the city of Baltimore, Maryland. It was described by the Urban Land Institute in 2009 as "the model for post-industrial waterfront redevelopment around the world". The Inner Harbor is located at the mouth of Jones Falls, creating the wide and short northwest branch of the Patapsco River. The district includes any water west of a line drawn between the foot of President Street and the American Visionary Art Museum. The name "Inner Harbor" is used not just for the water but for the surrounding area of the city, with approximate street boundaries of President Street to the east, Lombard Street to the north, Greene Street to the west, and Key Highway on the south. The harbor is within walking distance of Oriole Park at Camden Yards and M&T Bank Stadium. A water taxi connects passengers to Fells Point, Canton, and Fort McHenry. History While Baltimore has been a major U.S. seaport since the 18th century, the historically shallow water of the Inner Harbor (prior to manipulation through dredging) was not conducive to large ships or heavy industry. These were concentrated in Locust Point, Fell's Point, and Canton. In the mid-20th century, Baltimore suffered from the economic decline of restructuring common to many industrial cities in the United States. Old harbors were abandoned with the arrival of container ships after World War II. Later, the old harbors were adapted as focal points to reconnect cities with their waterfronts, and develop public spaces, tourism, business, and housing. During the 1940s, John H. Threadgill, the head of the Steamship Trade Association, initiated a study for a cross-harbor bridge. A bridge across the Inner Harbor of Baltimore was one idea that was discussed frequently. In his capacity as head of the association, Threadgill ultimately recommended that the idea for a cross-harbor bridge be abandoned, due to the fact that Baltimore relied heavily on a shipping trade and fears that the bridge would negatively impede the flow of shipping traffic at the Port of Baltimore. Threadgill was named head of Baltimore's Port Commission during the 1950s. In the 1950s, economic changes ended both the freight and passenger use of the Inner Harbor, such as the Old Bay Line's steamers. Rotting warehouses and piers were eventually torn down and replaced by open, grass-covered parkland that was used for recreational purposes and occasional large events.
