Detroit-Windsor | Gordie Howe International Bridge | 2,800' main span | U/C

[Steely Dan]

it looks like a very elegant design.

and at 816' tall, the towers will be taller than any of detroit's current skyscrapers.

[LMich]

At 816 feet, it's also going to be the tallest bridge in North America, maybe even the Western Hemipshere.

As for being taller than Detroit's skyscrapers, that's still in question dependent upon how many levels they decided to but at the top of the Hudson Tower, and whether the recent announcement that they are looking to fit a hotel into the tower means that they'll take out residential floors or add floors to the tower to accomodate the hotel. The 800 feet for it is a rough figure for sure.

No. Southern France would still own the "tallest in the world", though I couldn't tell how correct that assertion is.

Maybe the Chinese have taller things by now, Idk.
That is clearly the tallest in the country anyway.
Also a nice piece of French-British partnership.
Designed by Norman Foster and some fr structural engineer.

that's why i said "the towers will be taller than any of detroit's current skyscrapers".

hopefully hudson tower will be built to an even taller height.

[The North One]

Didn't realize this was going to be taller then the likes of the golden gate bridge, that's crazy. This is going to dwarf the Ambassador.

for real.

the ambassador's towers are only 386' tall.

the towers of this new bridge will be over twice as tall!

the new bridge towers will also be far taller than the mackinac bridge towers (552'), though its main span will be much shorter (2,800' vs. 3,800' for mighty mac)

Tallest in the Western Hemisphere, not the entire world. Millau lies east of the prime meridian from Greenwich (which runs near Bordeaux in that part of France) so it is in the Eastern Hemisphere.

In American usage, "Western Hemisphere" is usually used incorrectly to refer to the New World (the Americas plus Greenland and other islands).

But yes, this will be the tallest bridge in the world outside of Europe and Asia, beating out Mexico's Mezcala Bridge and the US' Golden Gate Bridge.

[seabee1526]

It is amazing when you see the Mackinac Bridge towers coming in at 552' above the straights.

[Docta_Love]

That's very true the Mackinac Bridge dominates the straits area as you come up 75 from the LP but then again the Mighty Mac is still the 3rd longest suspension bridge in the world and the longest in the western hemisphere, with the main span being near a mile and the total length of 26,372 feet or about 5 miles. The Gordie Howe will be taller with a much shorter length so the effect will definitely be dramatic although it will have more competition in an urban environment with two structures of similar height.

Gordie Howe bridge construction moves forward with groundbreaking in Detroit

By KURT NAGL
Crain's Detroit Business
July 17, 2018

-Gov. Rick Snyder and Canadian officials among those at event in Delray area
-$4 billion bridge construction expected to be complete by 2022 or 2023
-Project still faces potential barriers by Moroun family

After years of legal disputes and uncertainty, Michigan Gov. Rick Snyder and other local, federal and Canadian officials claimed victory in the battle to build a new span over the Detroit River.

The dignitaries symbolically broke ground Tuesday morning on the Gordie Howe International Bridge in the Delray area of Detroit, where neighborhoods have been dismantled and parcels of land cleared for the bridge's stateside international port of entry.

A similar groundbreaking is planned for the fall in Windsor, where the Canadian government has spent millions of dollars reworking roadways to connect with its future port of entry.

"This is an exciting day for Detroit, Windsor, Michigan, Ontario, the United States and Canada. After more than 7 years of hard work, today we broke ground on what will be a thriving legacy named for a legend," Snyder said in prepared remarks. "Gordie Howe represented the best of Canada and the United States. And, thanks to the hard work of many people on both sides of the border, now this bridge to the future will represent our prosperous partnership for generations to come."

While prep work has been ongoing on both sides, Tuesday's event marks the next step for the project. The bridge is expected to cost nearly $4 billion to construct and be complete by 2022 or 2023. Officials say they expect full construction to begin after financing closes in the fall. If all goes according to plan, the landmark project will result in the largest cable-stayed bridge in North America, with towers rivaling the height of the Renaissance Center.

Trudeau is going to be here for another grondbreaking for the project, which follows up on the news of its cost and schedule late last month. Prep work has been going on for months now.

Canadian Prime Minister Trudeau hails Gordie Howe Bridge in Windsor Friday

Windsor — Canadian Prime Minister Justin Trudeau continues his Windsor visit Friday to celebrate the start of construction for the Gordie Howe International Bridge, the Detroit-Windsor link expected to open in late 2024.

Trudeau arrived in this border city Thursday night for a Liberal Party fundraiser and on Friday morning he speaks at the Canadian Port of Entry about the significance of the future bridge. On Friday afternoon, he speaks at a community event near the bridge site

Anyway, found these additional (or larger) renderings:

Looks like last friday they filed an obstruction evaluation with the FAA for a 868-foot tower crane for the American side. They give the schedule for the crane as being from March 22, 2019 to September 16, 2020. So, we have a schedule for tower construction, at least on the Detroit side.

Also, it seems the 800+ feet number was for another design they were considering, but didn't end up going with. I wrote the bridge authority, and they said the current design is only 220 meters (722 feet).

722' is still really tall for bridge towers.

as i mentioned earlier in the thread the towers for the mackinac bridge are only 552' tall, and that bridge still looks massive.

[cabasse]

where is this going to be in relation to the existing ambassador bridge? apologies in advance if that's already been asked/answered - i scanned through previous pages and didn't see a rendering with perspective of what's already there.

I have a nostalgic attachment to the Ambassador, but it'll be nice to see that asshole billionaire's monopoly broken.

Maybe from a North American perspective that's tall, but that's pretty average here in China. There are three cable-stayed bridges across the Huangpu River and one across the Yangtze River in Shanghai alone that have similar tower heights (Yangpu Bridge, Xupu Bridge, Minpu Bridge, and Shanghai Yangtze River Bridge).

[skyfan]

After more than a decade of planning construction is finally ramping up. At 2,799 ft it will have the longest main span of any cable stayed bridge in North America and top 10 in the world.

Howe Bridge construction heats up

The small industrial buildings and blighted homes that once dotted the landscape of Detroit's Delray neighborhood are gone for good as demolition and site-cleaning work for the Gordie Howe International Bridge is in full swing this summer.

The long-anticipated bridge construction project is starting to take shape on the Michigan side of the Detroit River, as cranes have been working along the riverfront in recent weeks.

The cranes were drilling test shafts into the ground that will determine the final design of the new span and its towers rivaling Detroit's 73-story Renaissance Center, said Aaron Epstein, CEO of Bridging North America, the consortium of international infrastructure companies that is building the bridge.

Excavators are tearing up what's left of concrete foundations from one-time businesses in Delray that were uprooted through condemnation proceedings to acquire the 167 acres needed for the U.S. Port of Entry customs of plaza that will connect the new bridge to I-75. Some 255 buildings have been demolished in Detroit to make way for the new international crossing.

rane operators and construction companies are currently working to shore up the seawall along the Detroit River between Lafarge North America's riverfront aggregates plant and McCoig Concrete's plant where the new bridge will make landfall on the Michigan side.

On Springwells Court, an acre lot of modular office trailers totaling 28,000-square-feet has been installed to house the dozens of field engineers and support staff who will work on the construction project over the course of the next five years, Epstein said.

Construction Activities

US POE
Clearing is almost complete. DTE will decommission the remaining poles this week. Grubbing is ongoing and will be followed by site grading. Demolition of sidewalks has started, and a temporary detention basin was built. Assembly of site offices will be complete by mid-July.

US Bridge

BNA and their deep foundation subcontractor, Malcolm Drilling, successfully completed the O-cell test on July 3. This test comprises of four massive hydraulic jacks at the very bottom of the test shaft to measure the load resistance of the bedrock. Upon completion of this test, BNA designers will finalize the tower foundation so that work can commence later this summer.

CAN POE
Crews will continue to install erosion and sediment controls as necessary, establish construction entrances/exits, and prepare for wick drain installation for end of July and surcharging/earth works to start after that.
