In the U.S. state of Indiana, Interstate 70 (I-70) travels east–west across the state passing through the capital of Indianapolis. I-70 crosses from Illinois into Indiana near Terre Haute and departs into Ohio at Richmond. It covers 156.60 miles (252.02 km) in Indiana, paralleling U.S. Route 40 (US 40), the old National Road.
The Indiana portion of I-70 begins at the Illinois state line west of Terre Haute. Heading east, I-70 crosses the Wabash River soon after entering the state. US 40 travels concurrent with I-70 briefly before breaking off and traveling north of the interstate into the center of the city. The interstate crosses through the south side of Terre Haute, where it has an interchange with US 41/US 150. Just outside the city to the east, I-70 passes near Terre Haute International Airport before continuing onward to the east-northeast through rural lands towards Indianapolis. This stretch of I-70 does not have any interchanges with any significant cities until it reaches the Indianapolis metropolitan area, but it does pass within proximity of Greencastle.
Entering the Indianapolis area, I-70 passes through the southern reaches of Plainfield in Hendricks County, home to many logistics and warehousing companies. Shortly thereafter, it enters Marion County and the City of Indianapolis, passing just to the south of the Indianapolis International Airport, where the freeway now serves as the passenger terminal's main vehicular access point. Just beyond the airport, I-70 has an interchange with the I-465 beltway for the first of two times. Curving northeast, then east, the interstate then crosses the White River, passing just south of Lucas Oil Stadium and downtown Indianapolis before reaching I-65.
Turning north, the next section of I-70 along the east side of downtown Indianapolis travels concurrent with I-65. The two major interchanges at either end of this concurrency are often referred to as the "North Split" and the "South Split", forming the eastern leg of a section of freeways and surface streets locally known as the "Inner Loop" (as opposed to the "Outer Loop" of the I-465 beltway). The north split is also called the "Spaghetti Bowl" due to the visual complexity of the overlapping freeways, ghost ramps, and overpasses that were originally intended as a connection to a never-built portion of I-69. Upon leaving I-65 at the north split, I-70 reaches a maximum width of ten lanes (five in each direction) as it departs downtown Indianapolis toward the east-northeast. On the east side of town, I-70 again intersects with the I-465 beltway before departing the city, county, and metro area in a nearly due-east direction towards Ohio.
The portion of I-70 east of Indianapolis has been designated as the "Anton Tony Hulman, Jr. Memorial Way". Tony Hulman is most known for rescuing the Indianapolis Motor Speedway in 1945 and making the Indianapolis 500 popular. This stretch of I-70 does not have any interchanges with any significant cities until it reaches Richmond, but it does pass within proximity of both Greenfield and New Castle. On the northwest side of Richmond, US 35 joins I-70 and remains on the freeway as both routes jointly cross into Ohio. It also has an interchange with US 27 providing access to Richmond south of the interstate. On the east side of Richmond, US 40 intersects with I-70 immediately to the west of the Ohio state line.
Changes in the route
|This section needs expansion with: Overall history of route construction. You can help by adding to it. (January 2015)|
Between 2003 and 2005, I-70 was rebuilt about 1,000 feet (300 m) south of its original alignment on the western edge of Indianapolis. This reconstruction was done to allow expansion of runways at Indianapolis International Airport.
