I-29 Accidents in Western Iowa

I-29 is one of the roads I know best. I am intimately familiar with it, I drive it throughout the year, and I have represented clients hurt up and down it. I know the construction that has reshaped it around Council Bluffs, and I know the particular challenges of a highway that runs beside the Missouri River for most of its length. This page explains what makes an I-29 crash different, which rules apply, and what to do if you or someone in your family was hurt on it. For crashes on I-80, including the stretch I-80 shares with I-29 through Council Bluffs, see my I-80 page for Nebraska and Iowa.

The Road, From the Missouri Line to South Dakota

By the Federal Highway Administration’s count, I-29 covers 151.93 miles in Iowa, and its Iowa cities are Council Bluffs and Sioux City (FHWA route log, January 2026). For three of those miles it shares the road with I-80 in Council Bluffs, and for almost ten it carries I-880 as well. Between the two cities it passes Missouri Valley, where the I-29/US 30 interchange is Exit 75, and it meets I-680 and I-880 north of Council Bluffs. Iowa’s interstate speed limit is seventy miles per hour (Iowa Code § 321.285).

Council Bluffs: A Rebuilt Interstate With Old Habits Around It

The original interstate system through Council Bluffs was built to 1960s design standards and, in Iowa DOT’s words, “remained virtually unchanged until the early 2000s.” The agency describes it as “Packed with traffic and frequent crashes,” with many features that “did not meet today’s design standards” (Iowa DOT). The answer was the $1.5 billion Council Bluffs Interstate System Improvement Program, designed to “Modernize and improve 14 miles of interstate,” including what Iowa DOT calls the area’s first dual, divided freeway, where I-80 and I-29 run side by side.

A modern interchange still produces crashes when drivers misjudge it. Through Council Bluffs, I-29 carries Omaha commuters, long-distance through traffic, and trucks moving between two interstates in a short distance. Lane choices have to be made early, and late merges, sudden lane changes and rear-end crashes in slowing traffic follow when they are not. When I look at a crash in this stretch, the exact lane, the signs the driver passed, and the point where the vehicles came together all matter, so the first job is pinning down the location precisely.

When the River Takes the Road

Few interstates have a history with water like this one. I-29 runs through Missouri River bottomland, and when the river rises the road closes, sometimes for months.

• 2011. Iowa’s emergency management after-action report counted “54 miles of Interstate Highway” among the roads closed by Missouri River flooding. I-29 was closed from the Missouri border to milepost 32 from June 15 to October 8, from milepost 55 to 71 north of Council Bluffs from June 9 to September 23, and at Hamilton Boulevard in Sioux City from June 4 to September 1 (Iowa HSEMD).
• 2019. The Federal Highway Administration’s first estimate put flood damage in Iowa above $90 million, “with the damage on I-29 alone estimated at $40 million” (FHWA). Iowa DOT later wrote that the flooding caused I-680, I-29 and other routes “to go out of service for weeks or months” (Iowa DOT).
• 2024. Iowa DOT announced it would close I-29 from milepost 55, at 25th Street on the north edge of Council Bluffs, to the I-29/880 interchange near Loveland as the Missouri rose (Iowa DOT).
• 2025. In November 2025, Iowa DOT reopened a southbound lane of I-29 south of the South Dakota border in Sioux City after repairing damage “caused by last year’s flooding” along the Big Sioux River (Iowa DOT).

Floods matter to an injury claim long after the water goes down. Repairs mean lane closures, narrowed lanes and work zones, sometimes for a season or more. Detours push interstate traffic, including trucks, onto county roads that were never meant to carry it. A driver who comes over a rise at seventy into a lane closure is one of the most dangerous situations on any interstate, and the people in the stopped cars are almost never the ones at fault.

The Crashes This Road Produces

Two recent I-29 crashes I have written about, listed below, show the pattern. Near Crescent, the Pottawattamie County Sheriff’s Office said an earlier collision had closed the left lane and that a semi “failed to slow down for the traffic,” striking four stopped vehicles. Near Honey Creek, a semi split in half after striking a bridge column, killing the driver and a passenger. Neither post describes a case of mine; they are news, reported as the authorities described it. They do show the two hazards that come up again and again on this road: queues that form behind an earlier crash or a lane closure, and heavy trucks at highway speed with little room for error.

Iowa’s rules of the road speak directly to the first one. A driver “shall not follow another vehicle more closely than is reasonable and prudent,” with regard for the speed of traffic and the condition of the highway (Iowa Code § 321.307). In a rear-end crash into stopped traffic, that rule is usually the starting point of the liability case.

The Iowa Rules That Decide an I-29 Claim

Fault shared among several drivers

Iowa reduces an injured person’s damages by their own share of fault and bars recovery only when the claimant “bears a greater percentage of fault than the combined percentage of fault attributed to the defendants” and released parties (Iowa Code § 668.3). That is more forgiving than Nebraska’s rule, which bars recovery when the injured person’s fault equals or exceeds that of the defendants. When several drivers share the blame, a defendant found 50 percent or more at fault can be made to pay all of the economic damages, such as medical bills and lost income (Iowa Code § 668.4).

Seat belts

The other side will often ask whether you were buckled. In Iowa, not wearing a belt “shall not be considered evidence of comparative fault.” It can be used only to reduce damages, only if the defense first offers substantial evidence that it contributed to the injury, and by “an amount not to exceed twenty-five percent of the damages awarded” (Iowa Code § 321.445).

A drunk driver and the bar that served him

Iowa allows a claim against a licensee “who sold and served any alcoholic beverage directly to the intoxicated person, provided that the person was visibly intoxicated at the time” (Iowa Code § 123.92). Noneconomic damages against the bar are capped at $250,000 unless the jury makes specific findings, such as a substantial or permanent loss or impairment of a bodily function, substantial disfigurement, or death. The deadline that sinks these claims is the notice: “Within six months of the occurrence of an injury,” the injured person must give written notice to the licensee or its insurer (Iowa Code § 123.93). Nebraska has no comparable claim against a bar that served an adult driver, which is one more reason an Omaha family hurt on the Iowa side should not assume Nebraska rules.

Insurance

Iowa’s minimum liability limits are twenty thousand dollars for one person’s injuries, forty thousand for everyone hurt in the crash, and “fifteen thousand dollars because of injury to or destruction of property of others” (Iowa Code § 321A.21). Those numbers do not go far after an interstate crash. Every Iowa auto policy must include uninsured and underinsured motorist coverage unless the policyholder rejected it in writing (Iowa Code § 516A.1), and that coverage on your own policy is often where the real money is. See underinsured motorist coverage.

Work Zones and Stopped Vehicles

Flood repairs and rebuilding mean I-29 is rarely without a work zone somewhere. Iowa DOT reported 741 work zone crashes statewide in 2025 and 6,639 from 2016 through 2025 (Iowa DOT). Iowa doubles the scheduled fine for any moving violation in a road work zone, and speeding there carries fines from $195 for up to ten miles over the limit to $1,285 for more than twenty-five over (Iowa Code § 805.8A). Iowa’s move-over law protects people stopped on the shoulder, including stranded drivers, tow operators and troopers, and a violation that injures someone can bring an extra $500 fine, or $1,000 when someone is killed (Iowa Code § 321.323A). A citation is not a verdict, but it is evidence, and I want the records behind it.

Trucks on I-29

A commercial truck on I-29 is governed by safety rules that Iowa law requires to be “consistent with the federal motor carrier safety regulations” (Iowa Code § 321.449). That means hours-of-service limits, electronic logs, driver qualification files, inspection and maintenance records, and federal insurance minimums for interstate carriers. Those records are the backbone of a truck case, and they can be overwritten or discarded if no one demands them. I send preservation letters early. The details are on my truck accident page and my page on preserving truck crash evidence.

Nebraska Residents Hurt on I-29

Omaha-area drivers cross the river every day, and many of the people hurt on I-29 live in Nebraska. Living in Nebraska does not usually bring Nebraska law with you. Nebraska courts apply “the local law of the state where the injury occurred” unless another state has a more significant relationship to the issue (Griffith v. LG Chem America, 315 Neb. 892 (2024)). Iowa courts use the most-significant-relationship test (Moad v. Dakota Truck Underwriters (Iowa 2013)). For a crash on an Iowa interstate, both roads usually lead to Iowa law.

The deadline is where this bites. Nebraska allows four years for most injury claims; Iowa generally allows two (Iowa Code § 614.1). Nebraska’s own borrowing statute says that when a claim is based on another state’s law, “the limitation period of that state applies” (Neb. Rev. Stat. § 25-3203). There is a narrow exception for some Nebraska residents, but I treat two years as the deadline for any I-29 crash. More on Iowa’s clock is in my Iowa statute of limitations guide.

I am licensed in Iowa as well as Nebraska, and I take cases anywhere in both states. An I-29 case may be filed in the Iowa county where the crash happened, and I handle it there.

When the Claim Is Against the Government

Some I-29 crashes raise questions about the road itself: a closure that was not marked, a detour, a repair zone, a drop-off. Those claims exist, but they are narrow and the deadlines are strict. A claim against the State of Iowa is “forever barred” unless it is made in writing and filed with the director of the department of management within two years (Iowa Code § 669.13). A suit against a city or county must be brought “within two years after the alleged wrongful death, loss, or injury” (Iowa Code § 670.5). Both the State and local governments are protected from claims that a road was negligently designed or built if it met the engineering standards in effect when it was built, though for cities and counties that protection “shall not apply to claims based upon gross negligence” (Iowa Code § 670.4). In most I-29 cases the claim is against a driver or a trucking company, but when the road is part of the story, the government deadlines have to be identified in the first weeks.

After an I-29 Crash: A Short Checklist

• Pin down the location: the mile marker, northbound or southbound, and the nearest exit. On I-29 that also tells you the county and whether the Iowa State Patrol or a sheriff’s office took the report.
• Move to safety if you can, and turn on your hazard lights. A stopped car on an interstate is a target for the next driver who is not paying attention.
• Report it. Iowa has its own reporting rules; see where to report a car accident in Iowa.
• Photograph the scene, including any lane closure, detour or flood-repair signs, because those change quickly.
• Write down the truck’s company name and DOT number if a semi was involved.
• Get medical care the same day, and keep every record and bill.
• Talk to a lawyer before giving a recorded statement to anyone’s insurer, including your own.
• If alcohol was involved, mark the six-month dram shop notice on the calendar now.

Frequently Asked Questions

Does Iowa law apply if I live in Nebraska and crashed on I-29?

Usually, yes. Both Nebraska and Iowa courts generally look to the law of the state where the injury happened unless another state has a more significant relationship to the issue. For a crash on an Iowa interstate, that is usually Iowa.

How long do I have to bring an I-29 injury claim?

Iowa generally allows two years. Nebraska generally borrows the other state’s deadline when the claim is based on that state’s law, so plan on two years even if you live in Omaha. A claim against a bar requires written notice within six months.

Can I recover if I was partly at fault?

Yes, unless your share of fault is greater than the combined fault of the defendants and released parties. Your damages are reduced by your percentage of fault.

Will not wearing a seat belt ruin my Iowa claim?

No. In Iowa it is not comparative fault. It can reduce damages by no more than 25 percent, and only if the defense shows it contributed to the injury.

Who is responsible when a semi hits stopped traffic on I-29?

Usually the truck driver, and often the trucking company for the driver’s conduct and its own hiring, scheduling and maintenance. The truck’s logs, engine data and camera video should be preserved quickly.

Can I sue the state over a flooded or closed section of I-29?

Sometimes, but those claims are narrow. Iowa protects the State and local governments from many design and construction claims, and a claim against the State must be filed in writing within two years.

Do you handle cases in Sioux City and other parts of western Iowa?

Yes. I am licensed in Iowa and take cases anywhere in Iowa and Nebraska, including Council Bluffs, Missouri Valley and Sioux City.
