May 20, 2003: The curve seen here heading left (north) will be removed in 2018. In the decade since IA 363’s decommissioning, the ex-state highway has only been known by its county and city names, 55th Street and Sunset Street.
The Iowa DOT will remove the large curve of IA 150 west of Urbana, at former IA 363’s west end, after a two-vehicle collision resulted in the deaths of five people earlier this year. The four-way intersection near the curve will become the main intersection. Construction ($1.5 million) has a target period of fiscal 2018, although this was not included in the draft five-year plan released earlier this week.
The DOT released a 7-page study after the accident (link via Vinton Today website). Three-quarters of the traffic at the intersection runs east-west, heading to/from I-380. Southbound IA 150 will stop and northbound 150 will have a left turn. (The headline below is incorrect; it is not an S-curve.)
