This is a little late, but hey, so was the completion date of the project!<\/p>\n
The flyover ramp from northbound I-35 to westbound US 30 in Ames opened two days before the Iowa State-Iowa game<\/a>, alleviating one long-standing traffic headache for Des Moines metro travelers going to Ames.<\/p>\n This becomes the fourth interchange in Iowa where one of the ramps in a cloverleaf interchange \u2014 is a flyover instead of an inner loop. In the other cases, all exiting traffic leaves the mainline at the same time, then splits shortly thereafter.<\/p>\n There are quite a few pure cloverleafs left in Iowa, though, most notably I-80\/I-380 which is being turned into a turbine interchange. Others are at US 30\/61 in De Witt, I-29\/I-680 near Crescent, I-35\/US 20 near Williams, and I-80\/US 61 in Davenport. US 20\/75 on the east end of Sioux City was planned as a pure cloverleaf, but when the US 75 bypass was finally built the interchange became a six-ramp one instead. US 65\/69 is pretty much one, but the ramp from southbound 65\/westbound IA 5 to northbound 69 has a really hard right turn that isn’t really free-flowing.<\/p>\n","protected":false},"excerpt":{"rendered":" This is a little late, but hey, so was the completion date of the project!
