Nashville metropolitan area

The Nashville metropolitan area is located in the central part of the state of Tennessee, entirely within the Grand Division of Middle Tennessee, as defined by state law. Both the geographical center and population center of Tennessee are found in Murfreesboro, the second-largest city in the metropolitan area. Geologically, the metropolitan area covers most of the Nashville Basin, a geological dome. Parts of the region extend onto the Highland Rim, an elevated plain which completely surrounds the Nashville Basin. Both of these physiographic provinces are part of the Interior Low Plateaus of the Interior Plains. The highest point in the metropolitan area is Cannon County's Short Mountain, a monadnock that is an outlier of the Cumberland Plateau. The region is characterized by a combination of uneven rolling hills and relatively level plains, and is underlain with porous sedimentary bedrock such as limestone, sandstone, and shale, which form karst. As a result, the region contains many caves, underground streams, and depressions, and sinkholes are a common problem in the region.{{cite web |last1=Moore |first1=Harry |last2=Drumm |first2=Eric G. |title=Karst Geology in Tennessee |url=https://extension.tennessee.edu/publications/Documents/W453-C.pdf |publisher=University of Tennessee Institute of Agriculture |access-date=May 23, 2021 |location=Knoxville}}

Nashville is located in the northwestern corner of the basin, and most of Nashville's suburban growth has occurred to the south, southeast, east, and northeast of the city, due to the more level terrain of the basin. Much of the metro area contains extremely fertile soils, and crops such as corn and tobacco are commonly grown in the more rural parts of the metropolitan area. The Cumberland River passes through central part of the region, and is served by several tributaries, including the Stones, Harpeth, Caney Fork, and Red rivers.{{cite web|url=https://www.tn.gov/environment/program-areas/wr-water-resources/watershed-stewardship/watersheds-by-basin/cumberland-river-basin-barren-river-watershed.html|title=Cumberland River Basin & Barren River Watershed|author=|website=tn.gov|publisher=Tennessee Department of Environment and Conservation|access-date=June 23, 2020}} A small portion of the southern part of the metropolitan area, including most of Maury County, is within the drainage basin of the Tennessee River.{{cite web |url=https://www.loc.gov/item/2008628288 |title=Tennessee Valley Area: pictorial map |author= |date=1939 |publisher=U.S. Government Printing Office |access-date=June 23, 2020 |via=Library of Congress}} A small part of the northern part of the region is within the Green River watershed.{{cite web|url=https://www.tn.gov/environment/program-areas/wr-water-resources/watershed-stewardship/watersheds-by-basin/cumberland-river-basin---barren-river-watershed/barren-river-watershed.html|title=Barren River Watershed|author=|website=tn.gov|publisher=Tennessee Department of Environment and Conservation|access-date=June 23, 2020}} The Nashville metropolitan area is one of the most biodiverse inland regions in the United States, and is home to extremely rare ecosystems known as cedar glades, which are found in areas with shallow limestone bedrock that is largely barren of overlying soil, and are also one of the most endangered ecosystems in the nation, due to the rapid growth of the region.{{cite journal |last1=Quarterman |first1=Elsie |author1-link=Elsie Quarterman |title=Ecology of Cedar Glades.

Hickman County was removed in 2018,{{Cite web|url=https://bidenwhitehouse.archives.gov/wp-content/uploads/2018/09/Bulletin-18-04.pdf|title=Office of Management and Budget}} but was restored in 2023.

The Nashville-Davidson–Murfreesboro, TN, Combined Statistical Area (CSA) is the result of the addition of the Micropolitan Statistical Areas of Shelbyville (Bedford County), Lawrenceburg (Lawrence County) and Lewisburg (Marshall County) to the Nashville-Davidson–Murfreesboro–Franklin, TN, Metropolitan Statistical Area. The population of the CSA as of the 2020 United States census was 2,143,158.{{cite web|url=https://www2.census.gov/programs-surveys/popest/datasets/2010-2018/counties/totals/co-est2018-alldata.csv|title=County Population Totals and Components of Change: 2010–2018|website=www.census.gov}}

Three major interstate highways serve the Nashville metropolitan area, converging in downtown Nashville as a contiguous freeway loop. Most of the rapid growth of the Nashville metropolitan area has occurred along three major interstate highway corridors. Interstate 40 runs in an east-to-west direction, and connecting the region to Memphis to the west and Knoxville to the east. Interstate 65 runs north to south, and connects to Huntsville, Alabama to the south and Louisville, Kentucky to the north. Interstate 24, while technically an east-west interstate, runs in a northwest-to-southeast orientation, connecting the region to Clarksville to the northwest and Chattanooga to the southeast. Within the metro area, I-40 serves a suburban corridor that consists of the eastern neighborhoods of Nashville, including Donelson and Hermitage, and the cities of Mount Juliet and Lebanon. I-24 serves the suburban areas of Antioch, La Vergne, Smyrna, and Murfreesboro to the southeast, which is both the most populated and, in general, is the most congested corridor in the region. The I-65 corridor to the south consists of the suburban cities of Oak Hill, Berry Hill, Brentwood, and Franklin, and I-65 also serves the Nashville suburbs of Goodlettsville, Hendersonville, and Millersville to the north. Interstate 440 serves as a southern bypass around downtown Nashville, and Interstate 840 is an outer southern bypass around Nashville. State Route 155 (SR 155, Briley Parkway) is a freeway that bypasses downtown Nashville to the north and provides access to a number of tourist attractions including the Grand Ole Opry. SR 386 (Vietnam Veterans Boulevard) is a freeway that serves the suburbs of Hendersonville and Gallatin, and SR 396 connects Spring Hill to I-65.{{cite map|title = 2020 Official Transportation Map|year = 2020 |url = https://www.tn.gov/content/dam/tn/tdot/maps/state-maps/2020_Transportation_Map.pdf|publisher = Tennessee Department of Transportation|access-date = June 4, 2020}}
