This year will be full of preparation for extending US 20’s four lanes east from Moville, and there are construction events scheduled through 2018. The Sioux City Journal has coverage and a timeline.
IA 31 will be rerouted out of Correctionville this year, taking it away from the famous jog in the middle of town.
An infusion of cash from the 10-cent increase in the gas tax could mean that US 20 is four lanes across Iowa (except for the Julien Dubuque Bridge) by the end of this decade, which would be much faster than previous timetables. Double fences along 20 in far western Iowa show that some right-of-way has already been acquired, and that is part of what makes this project ripe for acceleration. (Say goodbye to that angled intersection with old 20 east of Cushing, though.)
