Thousands of Iowans will be hitting the road over the Memorial Day weekend and they’re being reminded to watch out for construction zones. Mark Bortle, with the Iowa Department of Transportation, says one of the bigger projects in central Iowa is along Interstate 35 from West Des Moines, south to just beyond the town of Cumming.

Other roadwork will impact travelers in western Iowa.

While the DOT will not be doing work in most construction zones over the holiday weekend, Bortle says motorists should still slow down when they see the black-on-orange warning signs and merge into the appropriate lanes as soon as they can.
