April 9, 2004: Once US 30 was expanded to four lanes around Colo, an exit tab was added to this sign. The interchange was constructed along with the realigned 30 in the 1960s but tapered back to two on either side. Finally, finally, the four-lane 30 was extended east of this interchange in 2010.
When the exit tab was added, though, it was put on the wrong side. As a right-hand exit, the tab should be on the right side. This was eventually corrected.
This sign mentions Des Moines although eastbound 30 traffic headed that way mostly would’ve exited at I-35. Either way, it’s the next major city south.
