Opponents of proposed tolls to help pay for the project have suggested following the example of Illinois and Missouri, which delayed construction of a second bridge to avoid tolls.

But during a Thursday meeting, Steve Schultz, executive director of the Ohio River Bridge Project Authority, said his research found big differences between the Ohio River project and the projects in the other two states.

The Courier-Journal reported the authority has concluded that $2.2 billion to $3.3 billion of the project's cost will come from tolls.
