Michigan has won approval from the Obama administration to build a second bridge between Detroit and Windsor, Ontario.
A presidential permit awarded Friday by the U.S. Department of State allows Michigan and Canada to move forward with their span over the Detroit River. Construction could be finished in seven years, though lawsuits challenging the project have been filed by owners of the current border bridge.
The key permit comes 10 months after Gov. Rick Snyder and Canadian Prime Minister Stephen Harper struck a deal by which Canada will pay for the bridge and five months after Michigan voters rejected an attempt by Ambassador Bridge owners to slow down or halt construction.
The State Department says granting the permit will "serve the national interest."
