Western Indiana

Just west of the town of Terre Haute, Interstate 70 in Illinois crosses the border into Indiana from St. Louis. At the town of Terre Haute one crosses the Wabash River and crosses US 41. The US 40 runs parallel to I-70 for a short distance here, both roads have 2×2 lanes. A 100-kilometer stretch then follows to the Indianapolis region. I-70 leads here through sloping to flat terrain with partly quite a lot of forest. Near Greencastle you cross the US 231. I-70 has 2×2 lanes all the way to the edge of the Indianapolis metropolitan area.

Indianapolis

I-70 then traverses the metropolitan area of ​​the state capital Indianapolis. The highway is rapidly widening here, with 2×3 lanes on the edge of the urban area to up to 15 lanes near the airport in the west of the city. It then crosses Interstate 465, which forms the Indianapolis ring road. I-70 then counts 2×3 lanes to downtown Indianapolis. At the center one crosses the White River, after which there is a short double numbering with Interstate 65 along the east side of Downtown Indianapolis. This part has 2×4 lanes. I-70 also has 2×4 lanes until the eastern interchange with I-465, then the highway has 2×3 lanes until just outside Indianapolis.

Eastern Indiana

There is then another 100 kilometer stretch to the Ohio border. Here, US 40 runs mostly south of I-70, also with 2×2 lanes. The highway leads through flat agricultural land with meadows and little afforestation. Also, no larger rivers are crossed here. The highway goes around the town of Richmond, where it crosses US 27, after which the border with Ohio follows. Interstate 70 in Ohio then continues toward Columbus.

History

The predecessor of I-70 was the US 40, which before 1960 already had 2×2 lanes throughout almost the entire state. The first section of I-70 to go under construction was the bypass of the eastern town of Richmond, which opened circa 1961. By 1965, it was already possible to bypass Indianapolis via I-465 along the south side of the city. The next major opening was the Terre Haute bypass, circa 1966/1967. In the late 1960s, construction progressed significantly, opening large portions west and east of Indianapolis, and by 1970, I-70 outside Indianapolis was complete. This made I-70 the second Interstate Highway in Indiana to open all rural routes, after I-74. Indianapolis’ entire urban highway network was built last, along with I-65. This section opened in 1976, completing both I-65 and I-70.

Widenings

The 2×3 lane portions of the urban core of Indianapolis were constructed directly like this in 1976.

Due to the construction of a new terminal at Indianapolis Airport, I-70 has been realigned west of I-465 with a parallel structure. This was constructed in the period 2003-2004. The highway here has been drastically widened from 2×3 to 14 lanes (4+3+3+4).

In 2012, a six-mile section of I-70 on the east side of Indianapolis was widened to 2×3 lanes.
