As of the 2020 Census, the county had a population of 657,974, making it the fourth-most populous county in Michigan, and the largest outside of Metro Detroit. Its county seat is Grand Rapids. The county was set off in 1831, and organized in 1836. It is named for New York jurist and legal scholar James Kent, who represented the Michigan Territory in its dispute with Ohio over the Toledo Strip.

The Grand River is a river in the southwestern portion of the southern peninsula of Michigan, United States, that flows into Lake Michigan's southeastern shore. It is the longest river in Michigan, running 252 miles (406 km) from its headwaters in Hillsdale County on the southern border north to Lansing and west to its mouth on the Lake at Grand Haven.
The Croton Aqueduct or Old Croton Aqueduct was a large and complex water distribution system constructed for New York City between 1837 and 1842. The great aqueducts, which were among the first in the United States, carried water by gravity 41 miles (66 km) from the Croton River in Westchester County to reservoirs in Manhattan. It was built because local water resources had become polluted and inadequate for the growing population of the city. Although the aqueduct was largely superseded by the New Croton Aqueduct, which was built in 1890, the Old Croton Aqueduct remained in service until 1955.

Larrys Creek is a 22.9-mile-long (36.9 km) tributary of the West Branch Susquehanna River in Lycoming County in the U.S. state of Pennsylvania. A part of the Chesapeake Bay drainage basin, its watershed drains 89.1 square miles (231 km2) in six townships and a borough. The creek flows south from the dissected Allegheny Plateau to the Ridge-and-valley Appalachians through sandstone, limestone, and shale from the Devonian, Mississippian, and Pennsylvanian periods.
Pine Creek is a tributary of the West Branch Susquehanna River in Potter, Tioga, Lycoming, and Clinton counties in Pennsylvania in the United States. The creek is 87.2 miles (140.3 km) long. Within Tioga County, 23.25 miles (37.42 km) of Pine Creek are designated as a Pennsylvania Scenic River.
Starrucca Viaduct is a stone arch bridge that spans Starrucca Creek near Lanesboro, Pennsylvania, in the United States. Completed in 1848 at a cost of $320,000, it was at the time the world's largest stone railway viaduct and was thought to be the most expensive railway bridge as well. Still in use, the viaduct is listed on the National Register of Historic Places and is designated as a National Historic Civil Engineering Landmark.
Tunkhannock Creek Viaduct is a concrete deck arch bridge on the Nicholson Cutoff rail segment of the Norfolk Southern Railway Sunbury Line that spans Tunkhannock Creek in Nicholson, Pennsylvania, in the United States. Measuring 2,375 feet (724 m) long and towering 240 feet (73.15 m) when measured from the creek bed, it was the largest concrete structure in the world when completed in 1915 and still merited "the title of largest concrete bridge in America, if not the world" 50 years later.
The Rosalia Railroad Bridge was built by the Chicago, Milwaukee, St. Paul and Pacific Railroad in 1915 to replace an earlier timber trestle. The bridge was designed as a concrete arch, unusual for a railroad bridge, because it crosses the Northern Pacific Railroad tracks, a state highway, and is visible from Steptoe Battlefield State Park. The railroad wanted an impressive-looking bridge. The viaduct consists of two spans, separated by an embankment. East of the 334-foot (102 m) embankment there is a 114-foot (35 m) span crossing over the Northern Pacific tracks. To the west is a 502-foot (153 m) span that crosses Pine Creek, railroad tracks, and the highway.
Plaster Creek is a 25.9-mile-long (41.7 km) urban stream in Kent County, Michigan in the United States. It is a tributary of the Grand River. The stream is named for the large deposit of gypsum found at its mouth. Its mean monthly flow averages 22 million gallons per day.
The US 41–Fanny Hooe Creek Bridge is a highway bridge located on US Highway 41 (US 41) over the Fanny Hooe Creek about one mile east of Copper Harbor, adjacent to Fort Wilkins State Park, in Grant Township, Michigan. It was listed on the National Register of Historic Places in 1999.
The M-26–Cedar Creek Culvert is a short highway bridge located on M-26 over Cedar Creek in Eagle Harbor Township, Michigan. The Keweenaw County Road Commission built the bridge in 1930; they also built the M-26–Silver River Culvert and the US 41–Fanny Hooe Creek Bridge around the same time. The M-26–Cedar Creek Culvert was listed on the National Register of Historic Places in 1999.
The Lyman Viaduct is a buried railroad trestle built over Dickinson Creek in Colchester, Connecticut in 1873. Along with the nearby Rapallo Viaduct, it is one of the few surviving wrought iron railroad trestles from the first generation of such structures. It was built for the Boston and New York Air-Line Railroad, whose successor, the New York, New Haven and Hartford Railroad (NYNH&H), buried it in sand rather than replacing it with a stronger structure. The viaduct was added to the National Register of Historic Places in 1986, since it is capable of providing detailed information about construction methods of the period. The viaduct now carries the multiuse Air Line State Park Trail.
The Massillon Bridge Company, most commonly abbreviated Massillon Bridge Co., was located in Massillon, Ohio and founded by Joseph Davenport in 1869. The company became incorporated in 1887 and remained in operation through the early 1900s. Steel truss bridges built by the Massillon Bridge Co. can be found throughout the midwest.
The Lockington Locks are a group of canal locks on the former Miami and Erie Canal in Lockington, Ohio, United States. Built beginning in 1833, the locks opened for regular use in 1845. The system consists of seven locks: six together at one end, and a seventh at the southern end. Along with features such as basins to allow canal boats to turn around, the locks stretch for 3.75 miles (6.04 km) between Lockington in far southern Shelby County and Washington Township in far northern Miami County.
The Minnesota and International Railway Trestle at Blackduck in Beltrami County, Minnesota was the longest timber trestle in the state. It was built in 1901 and 1902 by the Minnesota and International Railway, a subsidiary of the Northern Pacific Railroad, on a line between Koochiching and Bemidji, Minnesota, where it met a branch line of the parent railroad running north from Brainerd. The bridge carried the railroad over Coburn Creek and a difficult marsh in Blackduck and was noted for its considerable length and intact substructure when it was added to the National Register of Historic Places 2014.
The Third Street Railroad Trestle is a historic wooden railroad trestle bridge crossing Shoal Creek in downtown Austin, Texas. Built around 1922 by the International–Great Northern Railroad, it replaced an earlier bridge in the same place. The bridge was used by the I–GN Railroad, the Missouri Pacific Railroad, and the Missouri–Kansas–Texas Railroad until 1964, when commercial rail traffic stopped; after 1991 the bridge was abandoned. It was added to the National Register of Historic Places in 2021.
