The Iowa Department of Transportation’s road conditions map show that I-80 is closed in both directions between exit 57, east of Walnut, and exit 70, just west of Adair. A detour has been set up.  (As of 11:35, one-lane of I-80 eastbound was re-opened).

Authorities were cleaning up a crash near the grass fire. Iowa Department of Public Safety spokesman Sgt. Scott Bright says there were no serious injuries in the crash, and that officials do not believe the crash and fire are related.

Bright says officials shut down the stretch of I-80 for fear that smoke from the fire could cut visibility and cause collisions.
