The Iowa DOT has reduced Highway 92 to one lane as it starts construction work on the highway. The area of highway between Iowa Highway 5 and US Highway 63 is expected to be just one lane until they complete construction around July 2nd. Two pilot cars are in operation in Marion County; motorists can expect a delay of 15-20 minutes if using that route. Flaggers will be on the road between 6am and 8pm weekdays and Saturdays.
