AMES, Iowa – Sept. 20, 2019 – Area flooding has caused the Iowa Department of Transportation to close Interstate 680 from the Missouri River to the I-29 interchange near Crescent around 10 p.m. this evening.

Interstate 29 in the area was closed early this morning and is expected to remain closed over the weekend.

Relying on phone or in-vehicle navigation systems may not be reliable as closure changes happen rapidly and navigation systems can route traffic through areas not designed for heavy or some types of traffic.
