Ambassador Bridge in the context of "Grosse Pointe"

The Detroit International Riverfront is a tourist attraction and landmark of Detroit, Michigan, extending from the Ambassador Bridge in the west to Belle Isle in the east, for a total of 5.5 miles (8.8 kilometers) along the Detroit River. The International Riverfront encompasses a cruise ship passenger terminal and dock, a marina, a multitude of parks, restaurants, retail shops, skyscrapers, and high rise residential areas along with Huntington Place. The Marriott at the Renaissance Center and the Robert's Riverwalk Hotel are also situated along the International Riverfront.

Private companies and foundations together with the city, state, and federal government have contributed several hundred million dollars toward the riverfront development. Key public spaces in the International Riverfront, such as the RiverWalk, Dequindre Cut Greenway and Trail, William G. Milliken State Park and Harbor, and a cruise ship passenger terminal and dock at Hart Plaza complement the architecture of the area. The area provides a venue for a variety of annual events and festivals including the Detroit Electronic Music Festival, Detroit Free Press International Marathon, the Detroit International Jazz Festival, Motor City Pride, the North American International Auto Show, River Days and Detroit China Festival.

The Detroit River is an international river in North America. The river, which forms part of the border between the U.S. state of Michigan and the Canadian province of Ontario, flows west and south for 24 nautical miles (44 km; 28 mi) from Lake St. Clair to Lake Erie as a strait in the Great Lakes system. The river divides the metropolitan areas of Detroit, Michigan, and Windsor, Ontario—an area collectively referred to as Detroit–Windsor. The Ambassador Bridge, the Detroit–Windsor Tunnel, and the Michigan Central Railway Tunnel connect the cities.

The river's English name comes from the French Rivière du Détroit (translated as "River of the Strait"). The Detroit River has served an important role in the history of Detroit and Windsor, and is one of the world's busiest waterways. It is an important transportation route connecting Lake Michigan, Lake Huron, and Lake Superior to Lake Erie and eventually to Lake Ontario, the St. Lawrence Seaway and the Erie Canal. When Detroit underwent rapid industrialization at the turn of the 20th century, the Detroit River became notoriously polluted and toxic. Since the late 20th century, however, a vast restoration effort has been undertaken because of the river's ecological importance.

Windsor (/ˈwɪndzər/ WIND-zer) is a city in southwestern Ontario, Canada. It is situated on the south bank of the Detroit River directly across from the U.S city of Detroit, Michigan. Geographically located within but administratively independent of Essex County, it is the southernmost city in Canada and marks the southwestern end of the Quebec City–Windsor Corridor. The city's population was 229,660 at the 2021 census, making it the third-most populated city in Southwestern Ontario, after London and Kitchener. This represents a 5.7 percent increase from Windsor's 2016 population census of 217,188.

The Detroit–Windsor urban area is North America's most populous trans-border conurbation. Linking the Great Lakes Megalopolis, the Ambassador Bridge border crossing is the busiest commercial crossing on the Canada–United States border, carrying about one-quarter of the two countries' trade volume.

The 30 largest trade partners of the US represented 86.1 percent of U.S. exports, and 89.6 percent of U.S. imports in 2024. These figures do not include services or foreign direct investment.

In 2024, Mexico was the largest trading partner of the United States, followed by Canada and China.

The Quebec Bridge (French: pont de Québec) is a road, rail, and pedestrian bridge across the lower Saint Lawrence River between Sainte-Foy (a former suburb that in 2002 became the arrondissement Sainte-Foy–Sillery–Cap-Rouge in Quebec City) and Lévis, in Quebec, Canada. The project failed twice during its construction, in 1907 and 1916, at the cost of 88 lives and additional people injured. The bridge eventually opened in 1919.

The Quebec Bridge is a riveted steel truss structure and is 987 m (3,238 ft) long, 29 m (95 ft) wide, and 104 m (341 ft) high. Cantilever arms 177 m (581 ft) long support a 195 m (640 ft) central structure, for a total span of 549 m (1,801 ft), still the longest cantilever bridge span in the world. (It was the all-categories longest span in the world until the Ambassador Bridge was completed in 1929.) It is the easternmost (farthest downstream) complete crossing of the Saint Lawrence River.

Tourism in metropolitan Detroit, Michigan is a significant factor for the region's culture and for its economy, comprising nine percent of the area's two million jobs. About 19 million people visit Metro Detroit spending an estimated 6 billion in 2019. In 2009, this number was about 15.9 million people, spending an estimated $4.8 billion. Detroit is one of the largest American cities and metropolitan regions to offer casino resort hotels. Leading multi-day events throughout Metro Detroit draw crowds of hundreds of thousands to over three million people. More than fifteen million people cross the highly traveled nexus of the Ambassador Bridge and the Detroit-Windsor Tunnel annually. Detroit is at the center of an emerging Great Lakes Megalopolis. An estimated 46 million people live within a 300-mile (480 km) radius of Metro Detroit.

Detroit's unique culture, distinctive architecture, and revitalization and urban renewal efforts in the 21st century have given Detroit increased prominence as a tourist destination in recent years. The New York Times listed Detroit in its list of 52 Places to Go in 2017, while travel guide publisher Lonely Planet named Detroit the second-best city in the world to visit in 2018. In 2022, Detroit was featured in Time's The World's Greatest Places list.

The Detroit–Windsor tunnel (French: tunnel de Détroit-Windsor), also known as the Detroit–Canada tunnel, is an international highway tunnel connecting the cities of Detroit, Michigan, United States and Windsor, Ontario, Canada. It is the second-busiest crossing between the United States and Canada, the first being the Ambassador Bridge, which also connects the two cities, which are situated on the Detroit River.
