August 3, 2010: In the 1990s and 2000s, Missouri upgraded MO 152 to be a four-lane connector between I-29 and I-35 on the north side of Kansas City, but south of the airport. The use of Topeka as a control city is a little sleight of hand: MO 152 ends at I-435, 4 miles from the Kansas border, but MO 152/I-435/I-70 is a good way for Topeka/eastern Kansas traffic to get to I-35 without going through downtown.
