Here is The Sioux City Journal:

The Iowa Transportation Commission on Tuesday committed to widening half the mileage of U.S. Highway 20 with two lanes to four lanes by 2013.

The eastern Iowa two-thirds of the highway across Iowa was widened to four lanes many years ago, but the western portion has been delayed, leaving 86 miles with two lanes from Moorland to Moville.

Commissioners at the Muscatine meeting approved another 12 miles for four-laning Highway 20, from two miles east of Sac City at County Road N14 to U.S. Highway 71 at Early. The estimated cost is $48 million.

The president of Interstate Power & Light, who is also the former chairman and a longtime member of the Iowa State Transportation Commission, says four-laning U.S. 30 through Iowa is the “right answer,” while a plan to do the same with U.S. 20 is a project backed by more political arm-twisting than common sense.

Tom Aller, who is also senior vice president of energy delivery for the Alliant Energy Corp., which owns IPL, talked about the state’s transporation future in a wide-ranging interview with this writer, who doubles as a Carroll Daily Times Herald reporter and Iowa Independent fellow.

“When you run the models, four-laning Highway 30 is the right answer,” Aller said. “It diverts that traffic off (Interstate) 80 to a different route. When I was on the commission, I advocated for that solution. What I advocated also was that we didn’t spend another dime on (U.S.) 30 or (U.S.) 20 until we made that decision. My position on 30 was not anti-Carroll or western Iowa or pro-eastern Iowa. It was ‘let’s make a decision what we’re going to (do to) solve the I-80 problem.’ I could never get the commission to do that, including the last two years when I was chairman, because of the enormous political pressure in northwest Iowa to four-lane 20. I’m not on the commission anymore. But there is no justification for four-laning Highway 20. There is no computer model. If it was built tomorrow, there would never be any traffic on it.”

Aller served on the Iowa State Transportation Commission from 1995 through 2003, including serving as the chair from 2001-2003.

“The issue on I-80 east and west is probably the single most important problem we have facing the transportation system in Iowa,” Aller said. “It’s overloaded. It’s continuing to be overloaded. It’s dangerous to drive on. It’s increasing truck traffic. There are two potential solutions to relieving I-80. One is four-laning Highway 30. The other is four-laning Highway 20.”

According to the U.S. Highway 30 Coalition of Iowa, the Interstate 80 corridor has the most population (947,010), followed by U.S. 30 (524,562) and U.S. 20 (473,812). U.S. 30 is also the longest road in the state at 331 miles, stretching from the Mississippi to the Missouri.

One of the more divisive battles in western Iowa is over the priority in funding for U.S. 30 and U.S. 20.
