Posted on: March 16, 2019

AMES, Iowa – March 16, 2019 – 7PM – The I-29/U.S. 34/U.S. 275 interchange (exit 34) has now closed in Mills County due to a levee breach. Several flood closures remain in place for Interstates 29 and 680 as well as many surrounding roads and others throughout Iowa. Travel in Missouri and Nebraska is also being impacted by flooding, according to the Iowa Department of Transportation.

Interstate closures include:

  • I-680 in both directions
    between the Nebraska border and I-29 near Crescent (Mormon Bridge).
    The North portion of I-680 between I-80 and I-29 remains open for northbound traffic.
  • I-29 in both directions
    between the I-680 interchange (near Loveland) and North 25th Street in Council Bluffs.
  • Northbound I-29
    between U.S. 136 in Missouri (near Rock Port, MO) and the Iowa 92 interchange (in Council Bluffs).
  • The I-29/U.S. 34/ U.S. 275 interchange (exit 34 near Pacific Junction) has also been closed.
  • Southbound I-29
    between the I-80 interchange in Iowa (near Council Bluffs) and U.S. 136 in Missouri (near Rock Port, MO).

Local traffic is urged to check for current flood-related closures and detour routes. Detour routes and closures are changing rapidly, as levees continue to breach south of the Council Bluffs area.

Interstate 29 travelers are being detoured using the following route:

Northbound I-29 traffic is being detoured at I-35 in Kansas City, MO where travelers will continue north on I-35 into Iowa. From Des Moines, travelers will drive west on I-80 and continue onto I-680 to connect back with northbound I-29 in Iowa.

Southbound I-29 traffic will be detoured at Loveland onto eastbound I-680 where travelers will continue on to eastbound I-80 to Des Moines. From Des Moines, travelers will head south on I-35 into Missouri where travelers can connect with I-29 in Kansas City, MO.

Travelers should be aware that westbound I-680 on the detour route in Iowa is reduced to one lane due to damage from previous flood waters.
