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.
