Ohio road construction is a year-round reality, which makes sense when the Ohio Department of Transportation has to maintain more than 43,000 miles of highway .
Yet some projects, such as the plan to widen U.S. Route 33 near Columbus , are bigger than others.
What are the 10 most expensive ODOT projects of 2025? We won’t know the real answer for a few more months. Here’s why.
Why we have to wait to learn which road projects are Ohio’s most expensive in 2025
Visit ODOT’s projects page and you’ll see a slew of big-money construction projects on the agenda.
Some, such as the Brent Spence Bridge corridor construction in Cincinnati or the Interstate 70 and I-71 work in downtown Columbus , have costs that run to $1 billion or more. Even planned work with lower project costs have price tags that soar well into nine figures.
However, coming up with a definitive list of Ohio’s most expensive road projects at the start of the year is virtually impossible.
