July 10 (UPI) — Canada and the state of Michigan on Friday announced that a long-planned new bridge linking Ontario and Detroit will open at the end of July, 14 years after construction started.

The $4.4 billion Gordie Howe International Bridge between the two cities is set to open on July 27 and is set to offer improved transit on what leaders from Canada and Michigan called one of the busiest transportation corridors in North America.

The mile-and-a-half-long bridge includes new ports of entry on either side, with Canada and the United States establishing a 15-year economic development fund that has been tied to profits from crossing tolls.

President Donald Trump earlier this year threatened to prevent the bridge from opening over disagreements with previously existing trade agreements, his administration’s tariff regime and objections to Canada making trade deals with China.

“The Gordie Howe International Bridge has always been a great deal for our state,” Michigan Gov. Gretchen Whitmer said in a statement.

“Thousands of Michigan workers built this critical bridge, which will speed up auto production, lower costs, ease traffic, strengthen agriculture and give people on both sides of the border better-paying jobs and brighter futures,” she said. “This bridge is a testament to the enduring partnership between Michigan and Canada.”

The bridge project originated with the state’s then-Republican Gov. Rick Snyder agreeing to the six-line bridge because it would alleviate congestion accommodate future travel and create new transportation capabilities between U.S. and Canadian manufacturing regions.

Canada’s minister for housing and infrastructure, Gregor Robinson, hailed the completion and impending opening of the bridge as “strengthening one of the world’s most important trade corridors.”

“This nation-building project is a testament to what Canada can accomplish when we come together with a shared vision,” Robinson said in a statement.

“The Gordie Howe International Bridge will create new opportunities, strengthen our economy and bring economic benefits on both sides of the boarder for generations,” he said.
