October 27, 2011: This intersection on US 30, the north end of old IA 234, has had several non-fatal crashes in the past few years, KCCI reports.
The now-seeming tradition of trouble with at-grade intersections on roads upgraded to four lanes in Iowa continues, this time in State Center.
Left turns from US 30 into State Center have resulted in multiple crashes, KCCI reported last month. The median of US 30 is not wide enough for a stop sign in the middle. See also this Marshalltown Times-Republican story.
The KCCI story says advance intersection warning signs will be coming to the location. I expect them to be similar to the ones at the Springville intersection on US 151.
It’s taken Springville a decade just to get an interchange on the five-year plan. State Center likely has the room for one, at the cost of at least the Wolf Country Customs building. Since this is a very flat area, a bridge over 30 would have to be entirely built up. That’s what happened with US 218 at the Youngville corner, so it’s not impossible.
