Shocker: Houston made another list of cities with the worst traffic. Courtesy photo

Few things are more frustrating for Houston drivers than sitting in bumper-to-bumper traffic. You're late, you're stuck, and you're wasting time and gas — every single day. It's no surprise that the Bayou City has ranked inside the top 10 in a new list of cities with the worst traffic.

The average Houston driver lost 62 hours to traffic delays in 2023, according to Inrix's latest Global Traffic Scorecard. That's 16 hours more than the time tallied in 2022, and 20 hours more than the national average of 42 hours lost. Ouch!

Trends across the country after the pandemic continue to contribute to congestion. Remote work has led to a longer stretch of high-traffic hours instead of the usual pre-9 am and post-5 pm rush hour surges — and less predictable peaks at that.

"On any given day, everybody might be going into the office and no one is expecting it," David Schrank, a senior research scientist at Texas A&M Transportation Institute, told The Hill in June 2024. "What if next Monday everybody gets called in? Then boom — it's gridlock."

On top of that, truck-related congestion (as anyone driving across Texas knows) has increased with the continued rise of e-commerce and home delivery, with one truck equaling two to three cars on the road.

To see where congestion is the biggest problem nationwide, Stacker ranked the 25 cities in the U.S. with the most time lost per driver due to congestion, according to data from Inrix. Houston lands at No. 8, the worst in Texas. Of course, Houstonians don't need a new survey to tell them just how miserable our traffic is - as our late, beloved columnist Ken Hoffman expressed earlier this year.

Three other cities in Texas have made the top 25-worst list: Dallas is No. 17, Austin is No. 21, and San Antonio rounds out the whole list at No. 25.

Stacker's analysis includes how much delays cost drivers based on median hourly wages in each metro area, per the Bureau of Labor Statistics, and comparisons to pre-COVID-19 pandemic hours lost, measured in 2019. Inrix calculated commute times by looking exclusively at the time it takes to get to and from major employment centers based on anonymized GPS data.

Downtown speed is the speed at which a commuter should expect to travel 1 mile into the city's downtown or central business area during peak morning hours, and the first quarter of 2024 versus the first quarter of 2023 metric is the change in travel times during those two periods.

Houston drivers have the 4th worst commute in America, study finds

on the road again?

For better or for worse, it's finally been confirmed – Houston traffic is among the worst in the nation, according to a new study by Forbes Home.

Houston ranked No. 4 in the Forbes study, which analyzed 25 of the largest U.S. cities to discover the average commute times for workers. Using 2021 U.S. Census data, the report determined the average time spent traveling to work in Houston is 30 minutes, which is only the ninth worst commute time out of all cities on the list.

"No amount of personal playlist songs, audiobooks, podcasts, commuter coffee, or glove compartment snacks can make a tough commute more pleasant," the report said.

While the COVID-19 pandemic brought commuting to a halt for most workers, about 74 percent of Americans are back to making those early morning and afternoon drives to-and-from their employers. Work-from-home rates have continuously dropped since 2020, which isn't helping the rise in commute times.

Houston has nearly 1.75 million workers over the age of 16 living within the area, and only 4.6 percent of households don't have access to a car. Unless workers live very close to their jobs, it's otherwise pretty difficult to walk or bike to work in such a gridlock-stricken city.

It surely doesn't help that the study cites Houston's (unfortunate) fame for being the No. 1 most stressful U.S. city for workers as having a hand in its overall ranking. Add commuting to that list of stressors, and it all equals an unhealthy effect on the working population.

"Research by the National Library of Medicine has found that the longer the commute time, the less satisfaction with work and life as hours spent commuting daily can contribute to a decline in mental and physical health," the report said.

Elsewhere in Texas, Dallas (No. 9) and Fort Worth (No. 10) both made it into the top 10 with their respective commute times of 29.70 and 26.80 minutes. San Antonio ranked No. 16 with an average commute time of 25.40 minutes. Austin, surprisingly, ranked No. 18 overall with an average of 27.90 minutes.

The top 10 U.S. cities with the hardest commutes are:

  • No. 1 – Nashville, Tennessee
  • No. 2 – Charlotte, North Carolina
  • No. 3 – Jacksonville, Florida
  • No. 4 – Houston, Texas
  • No. 5 – Washington, D.C.
  • No. 6 – New York City, New York
  • No. 7 – Boston, Massachusetts
  • No. 8 – Los Angeles, California
  • No. 9 – Dallas, Texas
  • No. 10 – Fort Worth, Texas

Texas City ammonia plant acquired by Yara in $1.3 billion deal

Ammonia Acquisition

Yara North America, a subsidiary of Norwegian fertilizer and ammonia producer Yara International, has agreed to buy an ammonia production plant in Texas City for $1.3 billion.

The seller is GCA Holdings, an affiliate of Texas City-based chemical manufacturer Gulf Coast Ammonia, which is owned by private equity firms Lotus Infrastructure Partners and MB Energy.

The Texas City plant, with an eventual annual capacity of 1.3 million metric tons, is expected to start full production by the end of this year. Yara says the ammonia produced by the plant will serve its own fertilizer production system and its key customers.

During a recent call with analysts and investors, Magnus Ankarstrand, executive vice president and CFO of Yara International, said the plant holds the potential to become one of the company’s most profitable plants. The $1.3 billion purchase price, he added, “is a very attractive entry ticket to ammonia production in the U.S. at a very attractive cost.”

The Texas City plant will add to Yara’s holdings in the Lone Star State, as Yara is the majority owner of an ammonia, hydrogen and nitrogen production plant in Freeport.

Construction of the ammonia plant began in 2020, but technical and infrastructure issues delayed the project. On its website, Gulf Coast Ammonia says the plant represented a $600 million investment.

“Gulf Coast Ammonia is a world-class asset that required disciplined execution across development, financing, construction, and commercial structuring,” Philipp Pletka, managing director of Lotus Infrastructure Partners, says in a news release.

Trexlertown, Pennsylvania-based Air Products, which owns and operates the country’s largest hydrogen pipeline network, will continue to supply hydrogen and nitrogen for the plant under a long-term deal with Yara, according to the release.

However, the news comes two days after Yara International announced that it would no longer be purchasing ammonia assets in the Louisiana Clean Energy Complex (LCEC) from Air Products. In a separate release, Yara said it planned to reallocate funds toward "alternative mature U.S. ammonia investment opportunities with more competitive returns."

Houston hypersonic engine company lands $91M to accelerate production

Clean Speed

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were also named to the World Economic Forum's Technology Pioneers community earlier this summer.
