Travel directions

I-465 on the east side of Indianapolis.

The start and end point of I-465 is at the interchange with Interstate 65 on the south side of the city. The highway runs west from here in 2×3 lanes, through the southern neighborhoods of Indianapolis. The city is striking because it has few suburbs, unlike many other American cities. Just after the interchange with I-65, one crosses US 31, a major north-south axis in the state. One then crosses the River White, and the highway then curves slowly to the north. At Indianapolis airport, one crosses Interstate 70, the highway from St. Louis.

One then crosses several major roads, such as US 40 and US 36, which run to the west. Interstate 74 exits at the suburb Speedway, which is double-numbered with the ring. I-74 runs toward Peoria in Illinois. After that, 2×3 lanes will be available, and like so many highways in the United States, I-465 also has a wide left hard shoulder that can be converted to HOV lane or full 4th lane in the future. Northwest Indianapolis crosses Interstate 65 again, which leads toward Gary and Chicago.

The highway then passes through a business park, and intersects Interstate 865, a short highway connecting I-65 and I-465. I-465 turns east here, passing through the northern neighborhoods of Indianapolis. One then crosses the US 31 for the second time, which leads to the city of South Bend. Interstate 69, the highway to Fort Wayne and Lansing, begins on the northeast side of Indianapolis. The highway then turns in a southerly direction and then has 2×4 lanes. On the east side of the city, it again crosses Interstate 70, which leads to Dayton and Columbus. Not far after, one reaches the interchange with Interstate 74, which leads to Cincinnatiruns. A few kilometers later you reach the starting point again with Interstate 65.

History

I-465 on the west side of Indianapolis.

Indianapolis was historically an important interchange of US Highways, 6 US Highways converged in the city; US 31, US 36, US 40, US 52, US 136 and US 421. Before the construction of the highways, US 31, US 40 and US 52 had already been extended as a 2×2 divided highway to well outside Indianapolis.

As such an important intersection of through roads, the construction of I-465 was given priority, it was one of the first beltways of all Interstate Highways, large parts of which were built in the 1960s. The first part was constructed around the west and south sides of Indianapolis and opened in three phases between 1962 and 1964. This allowed north-south traffic and some east-west traffic to bypass the city. In 1965, all east-west traffic was also able to bypass Indianapolis via the ring road. After that, the North Ring and the North East Ring, which were built in a short time and completed by 1970, were missing.

I-465 was critical to through traffic from the start. Unlike many other American cities, the ring road was built earlier than the highways along the center. Most of I-65 and I-70 within the beltway were not opened until 1976.

Widenings

Large parts of Interstate 465 were widened and converted after 2000.

Western

The west ring of Indianapolis originally had 2×3 lanes, but has been phased out from 2×4 to 2×5 lanes over the period 2005-2014. First, the northernmost portion of the west ring has been widened, between I-65 and I-865, and finally, the portion immediately south of I-74, with the interchange converted from cloverleaf to turbine. The interchange with I-70 has been converted from clover turbine to semi-turbine.

North ring

The north ring originally had 2×3 lanes throughout. First, in the 2010-2013 period, the eastern half between US 31 and I-74 was widened to 2×5 lanes. Then a park with the Keystone Parkway was also built.

Eastern ring

The eastern ring was the first to be widened. As early as 1999-2003, the section between I-69 and I-70 was widened and interchanges were converted. Around 2001/2002 the interchange with the I-70 was converted from bow tie to modified turbine. The connection with 56th Street was converted from cloverleaf to parclo around 2004, including a parallel structure. Around 2003, the interchange with I-74 was also converted from cloverleaf to semi-turbine. North of this is a parallel structure to US 52, which has existed since at least the early 1990s, but was also modified around 2003.

Future

In the future, Interstate 69 will be routed over the East and South Rings of Indianapolis, connecting both parts of I-69.

Traffic intensities

Every day, 167,000 to 183,000 vehicles drive along the east side between I-69 and I-70, a dip of 110,000 to 120,000 vehicles between I-70 and I-74, 115,000 to 120,000 vehicles between I-74 and I-65 the southeast side, 105,000 to 120,000 vehicles between I-65 and I-70 on the southwest side, 115,000 to 140,000 vehicles on the west side between I-70 and I-74, and 115,000 vehicles further up to I-65. The link between I-65 and I-865 has 90,000 to 115,000 vehicles and 130,000 to 150,000 vehicles on the North Ring.
