August 31, 2008: IA 110’s south end is along the last big part of US 20 in Iowa that will be expanded to four lanes.
The DOT held a meeting a week ago today regarding an upgrade to the last major two-lane stretch of US 20 in Iowa. This covers the segment from the Ida/Sac county line east to US 71, which has an accelerated timeline from the increase in the gas tax. Most of this part of the four-lane will run north of the current section-line road (PDF map), possibly because of grooved pavement used in the center stripe right now. The segment farther west to Correctionville was covered in a meeting earlier this year.
The construction will require a detour (PDF). If you drive 20 right now, you can see that the future westbound lanes stop abruptly before a farmstead, which will be lost in the construction.
