Interstate 670 (Kansas–Missouri)
Interstate 670 (I-670) is a 2.81-mile-long (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 also makes up the south side of Kansas City's Downtown Loop, where it passes under the southern half of the Kansas City Convention Center.
