DES MOINES, Iowa (AP) – Crews are assessing damage to Iowa highways and beginning repairs now that the Missouri River has dropped to lower levels after a summer of flooding. Sections of the Interstates 29 and 680 are largely rubble, leaving workers with a daunting number of repairs and little time as winter approaches. Officials say they’ll fix as many roads as possible this fall and hope to have at least single lanes open on damaged stretches of interstate by December, but some work will have to wait until next year. Iowa Department of Transportation spokeswoman Dena Gray-Fisher says in some spots, “there isn’t any road left. You’ve got to start from scratch.” Gray-Fisher says a contract for bids will go out Friday to rebuild a badly damaged three-mile stretch of I-680.
