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 freeway 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 freeway 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[2] although maps list it as the Jay B. Dillingham Memorial Highway[3]. Dillingham was a former president of the Stockyards.

I-670 is the multi-lane road going to the right of downtown Kansas City across the West Bottoms by the confluence of the Missouri and Kansas Rivers. I-70 goes to the left of downtown Kansas City close to the bend in the Missouri River
