The new Gordie Howe International Bridge is hitting another milestone as the final U.S. tower crane will be removed from the site by the end of this week, the Windsor-Detroit Bridge Authority confirmed Monday.

The towering twin cranes have been visible in the Detroit and Windsor skylines for five years of construction work on the new publicly-owned Detroit River span.

The tower cranes arrived on site in 2020 and were assembled over three days, taking 35 hours, according to the bridge authority. They climbed in height throughout construction to keep up with the growing bridge in a process known as “tower crane self-climbing.”

In 2024, construction of the bridge towers reached 722 feet and this year the cranes reached 797 feet tall, their tallest height of the construction project.

A dismantling crew is removing the blue U.S. crane, colored to represent its home country, by week’s end, marking a major achievement in construction, according to the bridge authority.

The tower cranes guided rebar, concrete forms, anchor boxes and the cable-stayed bridge deck’s 216 cables into place throughout the construction, the bridge authority said.

On the Canadian side, the red tower crane, colored to represent its home country, was dismantled in May.

The bridge spans the Detroit River, connecting southwest Detroit to northwest Windsor, Ontario. When the $5.7 billion project is complete, at 150 feet above the Detroit River and 720 feet high, the Gordie Howe International Bridge will be the largest Canadian and U.S. land port along the border.

At half a mile long, the main span of the bridge will be the 10th-longest cable-stayed bridge in the world and the longest in North America, according to the bridge authority.

Bridge authority officials did not confirm on Monday when the bridge would open.

But officials have said the new bridge is expected to open this fall after construction wraps up in September.

Work on the bridge that remains ongoing includes installing lighting, barriers, signage, fire impression systems and the completion of a multi-use path that users will be able walk or ride bikes on, according to the bridge authority.
