March 22, 2003: Former south end of IA 341 at US 18 in Ruthven.
The DOT appears to be phasing out overhead amber and red lights at intersections across rural Iowa. Two news stories from opposite corners of the state — in the Emmetsburg News and Fairfield Ledger — cover plans to take out beacons at Ruthven (above) and Birmingham, so I think it’s fair to extrapolate a trend.
In place of the beacons on the road that stops will be solar-powered flashing stop signs, the News reports. I don’t know what the through road will get, most likely an “Intersection Ahead” sign with its own flashing amber light.
