Construction on Highway 92 near Indianola began Tuesday morning, after being delayed by the Iowa Department of Transportation earlier this week. The milling and overlay project, which began at the Warren County border on Highway 5, will cause one-lane traffic near the intersection of Highway 65/69 and cause delays. The lights at 12th Street and 15th Street will be set to flashing red during this time, and the City of Indianola asks that residents please use caution while driving in the area.
