Interstate 670 (abbreviated I-670) is a 2.81 mile (4.52 km) connector highway between I-70 in Kansas City, Kansas and I-70 in Kansas City, Missouri. The highway provides a more direct route through downtown Kansas City than the older mainline I-70, and avoids the sharp turn (and reduced speed limit) of the latter at the west end of the Intercity Viaduct. I-670 is also designated Alternate Interstate 70, one of the few interstates to be designated as an alternate. Interstate 670 also makes up the south side of Kansas City's downtown highway loop, where it passes under the southern half of H. Roe Bartle Hall.

The road crosses the Kansas River and the West Bottoms which was the former location of the Kansas City Stockyards, on the I-670 Viaduct. The leg of the highway west of I-35 has Kansas Department of Transportation signs proclaiming it the Jay B. Dillingham Freeway[1] although maps list it as the Jay B. Dillingham Memorial Highway.[2] Dillingham was a former president of the Stockyards.

Route description

The freeway begins with ramps from I-70 meeting to form I-670 just before a bridge over the Kansas River, which is located just south of the confluence of the Kansas and Missouri rivers. I-70 at that point comprises U.S. Route 24, U.S. Route 40, and U.S. Route 169. The freeway then crosses the KansasMissouri state line and enters Kansas City, Missouri. The road then interchanges with Interstate 35 before meeting its terminus at I-70. The freeway continues as I-70.[3]


The freeway was not part of the original planned freeways around Kansas City in 1955.[4] The section east of the I-35 interchange was built first and finished in 1968.[5][6] The western portion was not planned until 1971, and was not finished until several years later.[7][8] By 1987, the freeway was extended slightly westward in the downtown Kansas area,[9][10] but was not fully extended to I-70 until 1991, when it was fully opened.[11][12]
