"I don't know of any county that's definitively decided to use the local option sales tax," said Margaret Donahoe, executive director of the Minnesota Transportation Alliance.
The Aug. 1 deadline for approving the wheelage tax isn't in place for the sales tax, so counties may have put the sales tax on the back burner. For low population counties, the wheelage tax generates as little as $50,000 a year, and the sales tax option may ultimately be more attractive in those cases, Donahoe said.
"I think there's a certain amount of interest," she said.
When it comes to county engineers, there's interest in any new funding options, Greenwood said.
"Everybody's been beating the drum every year about just how short we are of funding," he said. "So it should come as a surprise to no one."
