Patrick McKenna, director of the Missouri Department of Transportation, on Wednesday said he will leave his post after almost nine years on the job.

McKenna announced his decision near the end of a meeting of the Missouri Highways and Transportation Commission in Poplar Bluff. He did not give a date for his departure and did not return messages seeking comment on his decision.

“I’ve never been more confident in the future of MoDOT… and with the leadership of the commission,” McKenna said. “It’s been a blessing for me to be a part of this, and it’s also a good time to recognize when it’s time to move on, and that’s what I’ll be doing.”

McKenna did not say whether he will be retiring or seeking other work. He said he had contacted the commission members individually on Tuesday to let them know his intentions.

“I have some family obligations to attend to, and I feel that the department is in good hands,” he told the commission.

McKenna was the deputy commissioner of the New Hampshire Department of Transportation when he was hired in 2015. He has presided over a massive expansion of the department’s highway construction program, known as the Statewide Transportation Improvement Plan, or STIP. When McKenna arrived in 2015, commission chairman Dustin Boatwright said during Wednesday’s meeting, the program averaged $325 million annually.

The program approved for the 2025 through 2029 fiscal years averages $4.4 billion annually.

The expansion is partially due to a 2021 increase in the state gas tax, which so far has added 10 cents per gallon to the previous levy of 17.4 cents per gallon. A final step next year will make the tax 29.9 cents per gallon on July 1, 2025.

MODOT has also benefited from increased federal funding under an infrastructure bill approved by Congress in 2021 and appropriations of general revenue, including $100 million a year for low-volume roads and $3.4 billion in one-time allocations for widening Interstate 70 and Interstate 44.

“We have a historic opportunity in front of us with the funding that we have been entrusted with by the General Assembly and the governor, and there’s no doubt in my mind, this team that we have will execute that flawlessly,” Boatwright said.

McKenna has also had friction with the legislature. 

In 2021, the Highways and Transportation commission sued the Office of Administration when Commissioner Ken Zellers refused to allow the commission to implement a pay raise plan that carried a price tag of $60 million. The highways commission wanted to stem turnover at MoDOT and attract new employees.

The raises were not included in the department’s legislatively approved appropriations.

That led six state senators — including state Sen. Cindy O’Laughlin of Shelbina, who has since become Senate Majority Leader and is expected to be Senate President Pro Tem next year, — in a February 2022 letter to the commission, to demand that McKenna either resign or be fired.

The highways commission filed the lawsuit to test constitutional language that is unique to the road fund. The Missouri Constitution states that the money deposited in the fund shall “stand appropriated without legislative action.”

Last year, Cole County Circuit Judge Cotton Walker agreed with the commission that it could use money in the road fund at its discretion. The decision is being appealed but no date has been set for oral arguments.

Commissioner Dan Hegeman, a former senator who signed O’Laughlin’s letter, praised McKenna on Wednesday for his professional demeanor in disputes with the General Assembly.

“He’s got a lot to be proud of as he takes on a new challenge that is going to be great for him and his family,” Hegeman said.

There was no discussion of who will take over as director or whether there would be an interim director during a search. McKenna stated there is a plan but gave no details.

“I know the commission has a plan that there will be no gap in leadership,” McKenna said. “I want the whole team to understand that it’s been an absolute blessing to be here.”
