The Great Lakes Seaway Trail, formerly named and commonly known as the Seaway Trail, is a 518-mile (834 km) National Scenic Byway in the northeastern United States, mostly contained in New York but with a small segment in Pennsylvania. The trail consists of a series of designated roads and highways that travel along the Saint Lawrence Seaway—specifically, Lake Erie, the Niagara River, Lake Ontario, and the Saint Lawrence River. It begins at the Ohio state line in rural Erie County, Pennsylvania, and travels through several cities and villages (including the cities of Buffalo, Niagara Falls, Rochester, Oswego, and Ogdensburg) before ending at the Seaway International Bridge northeast of the village of Massena in St. Lawrence County, New York. It is maintained by the non-profit Seaway Trail, Inc.
The Seaway Trail was first designated in 1978 as an 80-mile (129 km) byway leading from the Seaway International Bridge to the Thousand Islands Bridge. It was extended southwestward across the state of New York in the mid-1980s and into Pennsylvania in 1996. The byway is recognized as a state scenic byway by both New York and Pennsylvania (the latter designation coming in 2003) and was named a National Scenic Byway in two stages. In New York, the Seaway Trail became one of the first byways in the nation to be declared a National Scenic Byway when it received the distinction in 1996. The Pennsylvania portion of the byway was added in 2005. The Seaway Trail was officially renamed the Great Lakes Seaway Trail in 2010.
