Officials working on the new Detroit River International Crossing agree the $250-million U.S. Customs plaza will be approved and built.

Just who will pay for it remains undetermined.

Canada is already paying the entire cost of the $1-billion bridge construction, and for some road upgrades on the American side of the crossing.

Reporters on Wednesday asked Canada's Transport Minister Lisa Raitt if Ottawa might also end up paying for the U.S. plaza.

"Obviously, our point of view is that the United States Government should be paying for the customs plaza. We will continue to make that point," she said. "That being said, I want to be really clear, since it is a question that comes up, that we're not going to let disputes on financing affect the construction timelines."

Raitt was in Windsor to announce appointees to a pair of panels that will oversee construction and operation of the new bridge.

Michael Cautillo was named the CEO of the Windsor-Detroit Bridge Authority. He echoed Raitt's commitment.

"We've got to get at it, and we've got to get it done, and we'll get it done in the time frame that's been articulated," he said.

Cautillo said the project can get going despite not having that piece of puzzle in place.

Windsor Mayor Eddie Francis agrees.

"I don't think it's going to be the one thing that will tie up the new crossing going forward. The announcement today is a positive step forward in that regard," he said.

Michigan Gov. Rick Snyder said he is pushing Washington for funding.

Snyder promised he would continue “strong and ongoing dialogue” with Washington.

A coalition of labour and business groups called Economic Alliance Michigan is also lobbying in Washington.

Brett Jackson is with the alliance.

"Now we have very strong assurances from the Secretary of Homeland Security and from some officials more quietly on the administration side to say that they're open now to talking about it," Jackson said.
