Interstate 80 is closed between mile markers 266 and 267, with a 281-mile long detour to get around it: Eastbound through traffic must leave I-80 at Des Moines and travel north to another highway, then east to Dubuque  , where it can move south  to return to Interstate 80 at the Quad Cities, with westbound through traffic following the opposite route. Local traffic is being allowed, since this shuts off a 150-mile stretch of highway.
