Several state and county road projects begin this week in the vicinity of the U.S. Highway 169 and Iowa Highway 141, and motorists should plan to give themselves a little more time for travel.
The Dallas County Secondary Roads Department will be closing until further notice 128th Place between U.S. Highway 169 and Bouton while they work to repair a frost boil on the one-mile stretch of granular-surface road.
If the weather holds, crews could begin this week hauling on rock and grading the road, according to Dallas County Assistant Engineer Andy Case.
“I think it’s something they can get shaped up in a day or two,” Case said. “It’s just a matter of hauling in the rock and getting in there with skiploaders and our motor graders to clean up the ruts and fill everything back in and blade the road up.”
Only local and emergency traffic will allowed on 128th Place between U.S. Highway 169 and Bouton for the duration of the repair work.
Traffic on a short stretch of U.S. Highway 169 will be reduced to one lane for about two weeks while Iowa Department of Transportation (DOT) road crews repair approaches to the bridge over Beaver Creek south of 130th Street and west of Bouton.
Drivers crossing the bridge should expect single-lane traffic in alternating directions controlled by temporary traffic lights. A width limit of 17 feet is also in effect.
Repairs to bridge approaches become necessary when the roadbed rises or falls during winter freezes, which leads to an uneven alignment of the roadway surface with the bridge surface.
“That differential is a problem area every time with roads,” said Dennis Ward, Iowa DOT construction supervisor. “We keep trying new things, and we can’t quite get that figured out yet, that differential between movement and non-movement.”
Ward said contract workers with Hawkeye Paving will “saw out about 10 feet of that portion and go down there and do some rework and rebar and pour some concrete in.” He said he expects the work to be completed by April 18.
Traffic will also be barred from 130th Street between U.S. Highway 169 and M Avenue for the duration of the repair work.
The DOT will make similar bridge repairs on Iowa Highway 141 east of County Road R30. Eastbound and westbound traffic will be reduced to one lane in each direction with a 17-foot width limit. Ward said the provisional completion date for this work is also April 18.
To the west of Perry, I Avenue from 130th Street north to the Boone County line will also be closed until further notice while country road crews repair damage to the one-mile stretch of granular-surface road caused by excessive truck traffic.
The Dallas County Roads Department this week launched a real-time online road construction map to assist county residents with travel information.
