Blood, Trauma, and Biohazard Cleanup in Duluth, MN

Duluth is the county seat of St. Louis County, Minnesota, sitting at the western tip of Lake Superior, the world's largest freshwater lake by surface area.

The city is named for Daniel Greysolon, Sieur du Lhut, the French explorer who reached the area in 1679 to open fur-trade routes.

Duluth was first settled in 1850-51, platted in 1856, and incorporated as a city on March 5, 1870.

The 2020 census counted 86,697 people in Duluth, down from a peak of 107,884 in 1960 at the height of the iron-ore and shipping booms.

Census Bureau survey estimates for 2020-2024 count about 37,447 households in Duluth, averaging 2.18 people per household.

With Superior, Wisconsin, Duluth forms the Twin Ports, and its harbor is the farthest-inland deepwater port in the world - ocean-going ships reach it from the Atlantic via the St. Lawrence Seaway, some 2,300 miles away.

Duluth's Aerial Lift Bridge was built in 1904-05 as the first transporter (ferry) bridge in the United States and converted into a vertical-lift bridge in 1929-30; it was listed on the National Register of Historic Places in 1973.

The bridge leads to Minnesota Point, also called Park Point, a roughly six-mile sand spit that is the world's longest freshwater baymouth bar.

Nicknamed the 'Zenith City,' Duluth climbs a steep hillside above Lake Superior, a layout that has earned it comparisons to San Francisco.

Since 1977, Duluth has hosted Grandma's Marathon every June, run along the Lake Superior shore from Two Harbors into the Canal Park district.
