North Dakota
As bridge repairs add up, North Dakota might need to rethink approach, Gov. Kelly Armstrong says
GRAND FORKS — North Dakota has 1,325 bridges identified as needing repairs, according to a national report.
And of the 4,255 bridges in North Dakota, 11% — or 467 of them — are structurally deficient, according to data compiled and distributed by the American Road and Transportation Builders Association. North Dakota ranks No. 10 nationally for structurally deficient bridges as a percentage of total bridge inventory, according to the ARTBA.
It’s a statewide problem that may require a new approach, Gov. Kelly Armstrong says, because “there is no way a local county can repair every bridge they have — especially in rural counties.” Some money exists for repairs, the governor said, but there just won’t be enough to fix all of the structures on the ever-growing list of projects.
Perhaps a better plan, according to Armstrong, is to rethink the state’s bridge grid.
“I think eventually the state and (affected) counties are going to have to work out what a 21st-century infrastructure looks like,” he said.
Because of the evolving way North Dakotans live and do business, the state could probably do with fewer bridges, he believes.
“You wouldn’t build the bridge infrastructure the same way in 2025 that was done in 1925. Nobody’s making a living on a quarter-section of land anymore; farming’s an economy of scale. Some of this is, replace the ones you need,” Armstrong said. “You’re going to have to make some tough decisions, particularly if you’re someone that lives on the north side of that bridge or the south side of that bridge and now has to go 6 miles out of their way.”
In northeast North Dakota, where numerous streams and rivers make their way into the north-flowing Red River, the number of bridges needing repair is especially high. For example, three of the top four most-traveled structurally deficient bridges in the state are in Grand Forks County, according to the ARTBA national report.
Atop the list is the Kennedy Bridge, which carries traffic on U.S. Highway 2 across the Red River on the north edge of Grand Forks. No. 2 is the Interstate 29 bridge over Grand Forks’ DeMers Avenue, followed by a Cass County highway over the Sheyenne River. At No. 4 is a rural I-29 bridge over County Drain No. 11, also near Grand Forks.
The long list of bridge repairs in the immediate Grand Forks area is enough to add a certain edge to Nick West’s job as Grand Forks County engineer.
“It’s a little stressful,” West said. “But it’s also rewarding when you can fix them.”
As reported in 2024 by the Herald, Grand Forks County has the most locally owned bridges of any county in the state, at 284. Of those, the county owns somewhere around 250 — the number changes every year, West said. He keeps a list of bridges that are most worthy of attention and tackles a portion of the list each year.
Grand Forks County Administrator Tom Ford says West is “passionate about his job.”
“He has a plan,” Ford said, “and he’s doing an excellent job prioritizing what needs attention. But you fix a couple of bridges, and as you fix a couple, other ones still on the list are aging. You just take it a bridge at a time and culvert at a time and be as responsive as you can.”
The end goal, Ford said, is to repair and fix the people’s infrastructure, “but we can only address what the budget allows,” he said.
West, Ford said, probably feels like he’s playing “Whac-A-Mole,” the old carnival game in which players use a mallet to try to strike fake moles as they poke their heads from holes in a cabinet. As one mole dives into a hole, another arises elsewhere on the board. Over time, the game has become a metaphor for attempting to complete a nearly impossible and frustrating task.
To reduce the number of moles on the board — or in a real sense, the bridges on the list — funding will always be the hurdle, Armstrong, West and Ford all say.
“I’d be lying to you if I said there’s enough (funding) to fix them all,” Armstrong said, adding that fixing all of the bridges “shouldn’t be the goal” if the state someday does rethink its bridge infrastructure.
So-called Prairie Dog funding — dollars derived from oil and gas tax revenues — has been used successfully for bridge repairs, West said. Operation Prairie Dog was created in 2019 as House Bill 1066, which made changes to oil and gas production tax distribution formula.
The bill’s passage provided a “new source of infrastructure funding for cities, counties and townships in non-oil-producing counties and airports throughout the state,” according to a description on the North Dakota Treasurer’s Office website. It allocates up to $250 million of oil and gas tax revenue per biennium to three buckets: municipal infrastructure, county and township infrastructure, and airport infrastructure.
More state money is coming, Armstrong noted.
“We did some things at the legislative session where they moved more money directly to (the Department of Transportation) through (percent of market value), and it allows for more money to be used locally, for more county projects,” he said.
During his January budget address, Armstrong touched on the state’s infrastructure concerns.
“We have construction needs, and our budget addresses them head-on,” he said during the speech.
He proposed a $464 million bonding package to tackle big projects like a new State Hospital in Jamestown; airport projects in Grand Forks, Dickinson and Fargo; and a military gallery at the North Dakota Heritage Center.
“To repay these bonds, we propose increasing the percent of market value, or POMV, which is applied to the Legacy Fund to calculate the earnings available for use every two years,” he told lawmakers.
At the time, the POMV was 7% of the average five-year balance of the Legacy Fund, he said. Armstrong suggested a 1.5% increase, half of which to be used for repaying the bonds for the hospital, airport and Heritage Center projects, with the other half to be used to support state and local infrastructure projects.
The Legislature did not go along with the 1.5% increase to a full 8.5%, but did approve increasing the POMV to 8%. A portion of the increase — 30% — will be used for highway infrastructure projects.
Still, the governor says, it’s important to think about what future travel trends hold for state infrastructure.
“The reality is, our job is to get (the state’s ag products) from farm to market as quickly as possible. What that looks like and what that future looks like is probably different than what people have lived (throughout the years),” Armstrong said. “We’ll fix some of them, (but) there’s no way we’re going to be able to fix them all.”

Scientists discover ancient river-dwelling mosasaur in North Dakota
Some 66 million years ago, a city bus-sized terrifying predator prowled a prehistoric river in what is now North Dakota.
This finding is based on the analysis of a single mosasaur tooth conducted by an international team of researchers from the United States, Sweden, and the Netherlands.
The tooth came from a prognathodontine mosasaur — a reptile reaching up to 11 meters long. This makes it an apex predator on par with the largest killer whales.
It shows that massive mosasaurs successfully adapted to life in rivers right up until their extinction.
Isotope analysis
Dating from 98 to 66 million years ago, abundant mosasaur fossils have been uncovered in marine deposits across North America, Europe, and Africa.
However, these marine reptile fossils have been rarely found in North Dakota before.
In this new study, the large mosasaur tooth was unearthed in a fluvial deposit (river sediment) in North Dakota.
Its neighbors in the dirt were just as compelling: a tooth from a Tyrannosaurus rex and a crocodylian jawbone. Interestingly, all these fossilized remains came from a similar age, around 66 million years old.
This unusual gathering — sea monster, land dinosaur, and river croc — raised an intriguing question: If the mosasaur was a sea creature, how did its remains end up in an inland river?
The answer lay in the chemistry of the tooth enamel. Using advanced isotope analysis at the Vrije Universiteit in Amsterdam, the team compared the chemical composition of the mosasaur tooth with its neighbors.
The key was the ratio of oxygen isotopes.
The mosasaur teeth contained a higher proportion of the lighter oxygen isotope than is typical for mosasaurs living in saltwater. This specific isotopic signature, along with the strontium isotope ratio, strongly suggests that the mosasaur lived in a freshwater habitat.
Analysis also revealed that the mosasaur did not dive as deep as many of its marine relatives and may have fed on unusual prey, such as drowned dinosaurs.
The isotope signatures indicated that this mosasaur had inhabited this freshwater riverine environment. When we looked at two additional mosasaur teeth found nearby, slightly older sites in North Dakota, we saw similar freshwater signatures. These analyses show that mosasaurs lived in riverine environments in the final million years before going extinct,” explained Melanie During, the study author.
Transformation of the Seaway
The adaptation occurred during the final million years of the Cretaceous period.
It is hypothesized that the mosasaurs were adapting to an enormous environmental shift in the Western Interior Seaway, the vast inland sea that once divided North America.
Increased freshwater influx gradually transformed the ancient sea from saltwater to brackish water, and finally to mostly freshwater, similar to the modern Gulf of Bothnia.
The researchers hypothesize that this change led to the formation of a halocline: a structure where a lighter layer of freshwater rested atop heavier saltwater. The findings of the isotope analyses directly support this theory.
The analyzed mosasaur teeth belong to individuals who successfully adapted to the shifting environments.
This transition from marine to freshwater habitats (reverse adaptation) is considered less complex than the opposite shift and is not unique among large predators.
Modern parallels include river dolphins, which evolved from marine ancestors but now thrive in freshwater, and the estuarine crocodile, which moves freely between freshwater rivers and the open sea for hunting.
Findings were published in the journal BMC Zoology on December 11.
