MADISON -- A new audit shows huge cost overruns at the Wisconsin Department of Transportation, with dozens of projects costing double or triple their original estimates.wisdot

The Legislative Audit Bureau report finds that estimated costs for 19 major projects completed between 2006 and 2016 were $1.5 billion, double the initial projection. The audit also finds that the estimated costs of 16 ongoing major highway projects have increased by $3.1 billion.

"When you see a department that you can say is so poorly managed, it`s stunning. It`s absolutely stunning," said state Rep. Joe Sanfelippo, R-New Berlin.

Auditors said, in some cases, DOT leaders didn't account for inflation. Lawmakers on Thursday, January 26th said the cost overruns proved the need for major changes at the agency, but it's unclear how the audit will impact the looming debate over the nearly $1 billion shortfall in the state transportation fund.


The biggest ongoing boondoggle was U.S. Highway 10 from Appleton to Marshfield, a project conceived in 1989. The initial estimate for all of the roadwork was $125 million; costs have ballooned to $547 million, an increase of 338 percent.

Roadwork on U.S. Highway 12 between Lake Delton and Sauk City was projected to cost $50 million in 1993; the transportation department estimates that it will cost $209 million now.

The biggest discrepancy on a project in southeast Wisconsin was the Burlington Bypass, where costs have increased to $123 million from $71 million since 1997.

Some lawmakers questioned if the DOT was providing the Legislature with artificially low estimates to get the projects approved.


"I think those conversations are going to be had in the next couple weeks here, as we have hearings on this audit and bring the secretary in," Rep. Samantha Kerkman, co-chair of the Joint Audit Committee said. "They’re giving us a price that doesn’t account for everything a road actually costs."

Patty Mayers, a spokeswoman for the DOT, did not directly respond to an email seeking comment about whether the agency was low-balling the Legislature. Instead, she pointed to a response from DOT Secretary Dave Ross contained in the audit.

Ross told auditors that the DOT has implemented changes to its cost-estimating system over the past six years, and auditors were looking at projects that began before the agency made those changes.

The agency will implement auditors' recommendations, Ross said.

"The Legislative Audit Bureau report provides a roadmap to improved efficiency and transparency at the DOT," Ross said in a statement to reporters. "As the new Secretary, I couldn't ask for more timely help.


Ross has been on the job for three weeks. The former secretary, Mark Gottlieb, resigned in early January after he told lawmakers that road conditions would worsen under Gov. Scott Walker's budget.

Walker has proposed to delay major projects and borrow $500 million to plug the transportation fund shortfall. Gottlieb said that wouldn't allow the entire interstate system around Milwaukee to be rebuilt for 70 years.

While Gottlieb had his supporters in the Legislature, Sanfelippo said the audit proves that he needed to go.

"It`s not very good, and if I was the head of that department -- which now we have a new secretary -- but he`s definitely walking into a mess, and I hope he`s up to the job of straightening it out," Sanfelippo said.

Sanfelippo said he gave Walker "a little bit of slack" for the problems at the DOT, which is under the governor's control. Walker on Thursday used the audit to reinforce his position against an increase in the state gas tax or vehicle registration fees to pay for roads.

The bottom line is we shouldn’t even be thinking about raising the gas tax or fees until we find every last cost savings at the DOT, and the audit shows we can find more savings," said Tom Evenson, a spokesman for Walker.

Assembly Speaker Robin Vos, who opposes Walker's road funding plan, said the audit demonstrated a need for an increase in transportation revenue along with cost savings.

"The legislative audit is yet another independent report that illustrates construction delays are driving up costs unnecessarily, our road conditions are only getting worse, and a long-term solution is needed," said Vos, R-Rochester, in an emailed statement.

Democrats criticized Walker for the scathing audit.

"The GOP has let the taxpayers of Wisconsin down. We are in a crisis state, and we need to take immediate action," said Assembly Minority Leader Peter Barca, D-Kenosha.



  • Herb

    All of the idiots in the Wisconsin legislature, including Barca are responsible for this. Both sides once again have failed EPICALLY to do the peoples business.

  • My Humble opinion

    Leave the road builders to their own devices what else do you expect.
    No oversight, no repercussions ( penalties) for going over budgeted cost, and projected time given for the projects. Everyone and their brother with their hands in the kitty , unlimited overtime, while all of them knowing full well this goes on again and again. And it does not seem to matter who’s in charge Dems or Republicans , maybe it’s time to hold the Companies doing the construction accountable for their overruns. And if your expecting someone to stand-up to them , well … do hold your breath.

    i agree with all the comments! The idiots that run this state should be locked in jail! That is just criminal!

    Sounds like unions run amuck. It used to be a few million to build a complete highway project, Now it’s many billions. Somebody is cooking the books.

  • All the civic engineers need to go as well

    Of course it’s going to be expensive and have over runs.. Have you seen the crazy things they are doing with the freeway rebuilds around Milwaukee? You have to take a Southern ramp to go North and the Northern ramp to go South at Watertown Plank Road.. its counter-intuitive and dangerous, not to mention the excessively extra amount of concrete required for all the insanely long ramps they are putting in. Who ever designed this re-design should be thrown out of civic engineering. All of the redesigns are needlessly excessive, it’s no wonder we can’t keep up with the road repairs.

  • Hell in a Handbasket

    Appears many of these cases of Fraud, Waste and Abuse occurred under Governor Doyle but no mention of his name from the Dems and CNN 6’s Theo Keith, pretty typical.
