According to Ehuacom, Indianapolis is the capital of the state of Indiana in the United States. The city has 882,000 inhabitants and is the 15th largest city in the country. The agglomeration has 2,127,000 inhabitants (2021). Indianapolis is the third largest state capital in the United States (after Phoenix and Austin).
According to mcat-test-centers, Indianapolis is notable for the fact that there are few suburbs. The majority of the metropolitan area consists of the city of Indianapolis itself, and is primarily located in the 977,000-population Marion County. It is one of the more important cities in the Midwestern United States, and is centrally located in the state of Indiana on the White River. The city is located 160 kilometers northwest of Cincinnati, 170 kilometers north of Louisville and 265 kilometers southeast of Chicago.
The city is located at a convergence of Interstate Highways and is therefore also called the ‘crossroads of America’. The agglomeration is located in fairly flat terrain, the area mainly consists of meadows. Unlike many cities in the eastern Midwest, the so-called Rust Belt, Indianapolis has not lost population since the 1950s, but has grown strongly, partly due to the annexation of surrounding areas. The counties surrounding Marion County are also growing strongly by Midwestern standards. The economy is based on services, although this used to be more related to industry. The region is known for affordability of housing, which makes it an attractive city to live in, which has resulted in a strong population growth. Indianapolis is after Dallas the largest city in the United States not located on a large waterway.
The highway network of Indianapolis.
Indianapolis has a full beltway, I-465. I -65 comes from the south, heading northwest, while I-69 starts from the ring road, heading northeast. I -70 forms an east-west connection, and I-74 a diagonal east-west connection from the northwest to the southeast. Almost the entire highway network of the agglomerate Indianapolis consists of Interstate Highways, which is quite unique. US 31 and SR-431 in the north of the city have also been developed as a freeway. In addition, some main roads have grade-separated intersections here and there, but cannot be qualified as highways. The highways converge at the center of town, and I-65 and I-70 are double-numbered here near the center. I-74 runs through the ring road.
In addition, Indianapolis is a center for several US Highways, which radiate to all parts of the state. This central location has allowed Indianapolis to benefit from economic growth. In particular, I-65 and I-70 are the main highways. The highway network is relatively adequately developed, with 2×3 lanes in many places, but also wider in places, especially along I-465, where parts also have 2×5 lanes.

The suburb of Carmel is located north of Indianapolis and is nationally known for its many roundabouts. It is the only place in the United States where roundabouts have been implemented on such a scale. On November 17, 2016, the 100th roundabout in Carmel was inaugurated.
Indianapolis in 1965. The city was one of the first to have a major beltway.
Construction of the Indianapolis highway system began in the late 1950s, and the first section, Interstate 74, opened in 1960. In 1961, the first section of I-465, Indianapolis’ ring road, opened. During the 1960s and early 1970s, the highway network around Indianapolis was completed. The last link was also one of the most important, when the double-numbering of I-65 and I-70 opened in downtown Indianapolis in 1976. No new highways were opened between 1976 and 2012, but highways were widened, especially the I-465 ring road. The main population growth has been on the north side of Indianapolis, in Hamilton County. To facilitate this, US 31 and State Route 431 were developed as a freeway around Carmel between 2010 and 2015.
Congestion occurs in Indianapolis, but is relatively limited. Major delays are an exception. The underlying road network is well developed and expanded, making it a reasonable alternative during incidents on the highways. Since 2000, the I-465 ring road has largely been widened, greatly reducing congestion here. A vulnerable part of the urban highway network is the double numbering of I-65 and I-70 where traffic converges on 2×3 lanes. In addition, there are a number of points around the center where exits merge on the left.
