The 'Twin Ports' of
Duluth,
Minnesota and
Superior,
Wisconsin are located at the western part of
Lake Superior (the westernmost of
North America's
Great Lakes). They are
twin cities and
seaports, connected to the
Atlantic Ocean through the Great Lakes and the
St. Lawrence Seaway. The Twin Ports are at the core of the
U.S. Census Bureau's "Duluth-Superior
Metropolitan Statistical Area", which includes all of Wisconsin's
Douglas County, and Minnesota's
Carlton and
St. Louis counties. With a 2000 census population of 275,486, the Duluth-Superior MSA ranked as the 163rd largest metropolitan area in the United States.
The area is home to two very long bridges: the
Richard I. Bong Memorial Bridge (carrying
U.S. Highway 2) and the
John Blatnik Bridge (carrying
I-535 and
U.S. Highway 53). While their central spans are not notably lengthy, the overall lengths are very impressive, with each reaching across more than 1.5 miles (2.5 km) of water.

The Aerial Lift Bridge in 1990
However, when visitors to the area come to see bridges, they pay much more attention to the historic
Aerial Lift Bridge that serves as a gateway to the port. It must be raised and lowered whenever ships enter or exit the Duluth side of the harbor, though the natural inlet closer to Superior doesn't have anything over it.
Together, the cities rank as the 19th-busiest port in the country overall (44.2 million
short tons
[40.1 million metric tons
] per year) as of
2002, though the area is the 7th-busiest port (13.8 million short tons
[12.5 million metric tons
] per year) when measured on foreign
exports alone.
