The Most Stunning Bridge in North America Is a Border Crossing

Posted on by

Most border crossings are things you endure. This one is something you look at. That’s what AECOM’s Erik Behrens set out to create with the Gordie Howe International Bridge, the new crossing between Detroit, Michigan, and Windsor, Ontario, that opened to traffic on July 27, 2026 — and promptly became the longest cable-stayed bridge in North America.

The numbers are easy to reach for. An 853-meter main span. Twin towers standing 220 meters tall. A total length of 2.5 kilometers, six lanes of traffic, a dedicated pedestrian and cycling path, and a projected lifespan of 125 years. The construction cost ran to CA$6.4 billion, funded entirely by the Canadian federal government and to be recovered through tolls. It links Interstate 75 on the American side to Highway 401 in Ontario — freeway to freeway, no traffic lights, no city streets swallowing the flow. But the engineering is almost beside the point when you see it.

Designer: Erik Behrens of AECOM

Behrens, a German architect working as chief bridge architect at AECOM, shaped the towers to echo the curvature of a hockey stick mid-slapshot — a direct nod to Gordie Howe, the Canadian-born legend who spent 25 years with the Detroit Red Wings and died two years before construction began in 2018. The A-shaped towers rise on opposite banks of the Detroit River, anchoring 216 stay cables in crisp white that catch the light and shift as you move around them, producing what Behrens describes as “a subtly shifting moiré” — a quiet kinetic elegance that reveals itself from every angle.

“The bridge captivates through a precise interplay of form, light and movement,” Behrens said. “Its paired arrays of white stay cables endow the structure with a sculptural depth that reveals itself from every angle.” The cables are slender enough to read as almost transparent against the sky, gravity-defying in appearance if not in fact.

The structure’s lighting was commissioned to Canadian artist Douglas Coupland, who designed ‘Shimmer’ — a programmable show using nearly 5,000 white bridge lights. “It’s a relief to see infrastructure that feels like it belongs to this century,” Coupland said.

Public art is woven throughout: Indigenous artwork by Walpole Island and Caldwell First Nation artists adorns the Canadian tower; Southwest Detroit artist Roberto Villalobos handled the American side. A 3-meter sculpture by Anishinaabe artist Michael Belmore greets arrivals into Canada. “Bridges must do more than function,” Behrens said. “They must belong, endure, and inspire.” The Gordie Howe International Bridge does all three.

The World’s Longest Single-Mast Bridge Has Arrived

Posted on by

At the mouth of Taiwan’s Tamsui River, a new landmark has quietly redrawn the skyline. The Danjiang Bridge, designed by Zaha Hadid Architects, has opened as the world’s longest single-mast, asymmetric cable-stayed bridge — a record-breaking piece of infrastructure that manages to feel more like a gesture than an imposition on its surroundings.

The project stretches 920 meters between New Taipei City’s districts of Tamsui and Bali, held aloft by a single concrete mast rising 200 meters above the estuary. That restraint is intentional. Where most bridges of this scale rely on a sequence of towers or supports planted through the riverbed, ZHA stripped the structure down to one vertical element — tall and slim enough to leave the horizon largely intact. The main span reaches 450 meters to the west of the mast, with a 175-meter span to the east, and cables fan outward asymmetrically from the tower in a sweeping, almost calligraphic arrangement.

Designer: Zaha Hadid Architects

The 71-meter-wide deck is built for a full range of movement. It carries motor traffic, dedicated pedestrian paths, cycle routes, and has been designed to accommodate a future extension of the Danhai Light Rail network — making it less a single-purpose crossing and more a layered piece of public infrastructure. ZHA director Patrik Schumacher described the design as one that would “make a conspicuous landmark against the backdrop of Tamsui’s famous sunsets,” and the placement of the mast against open water at dusk delivers exactly that.

Getting the form right required careful environmental modeling. The original competition brief placed significant weight on protecting views of the river’s famously photogenic sunsets, and ZHA used detailed mapping to ensure the mast’s silhouette — tall and linear — would read as a marker rather than a barrier in the landscape.

Engineering had to match Taiwan’s seismic reality. The support system is built to withstand earthquakes of magnitude 7 or above, combining pier supports, cable stays, hydraulic dampers, friction pendulum bearings, and synthetic rubber pads that work together to absorb both vertical and horizontal force. The structure is doing considerable technical work beneath its clean exterior.

ZHA won the Danjiang Bridge International Competition in 2015, and construction ran from that year through to 2025. For a firm whose identity is closely tied to cultural buildings and interior spaces, the bridge represents something different — a piece of civic infrastructure where the signature fluid language has been channeled into cable geometry, seismic engineering, and a view that already mattered deeply to the city it now connects.

This House in Rural India Is Actually a Bridge — and It’s Covered in Scales

Posted on by

Most architects would see a seven-metre-deep gorge cutting through a site and call it a problem. Vinu Daniel and his studio, Wallmakers, looked at it and saw the house. The Bridge House in Karjat, Maharashtra, is exactly what its name promises — a weekend home that spans a 30-metre-wide spillway, with enough clearance below for diggers to pass through. Completed in 2025, the 4,500-square-foot structure sits across two parcels of land separated by two streams, and it does so with a quiet, almost organic confidence.

The structural logic is deceptively simple. Four hyperbolic parabolas form the spine of the suspension bridge, held together by minimal steel pipe and tendons working in tension. Over that skeleton, a grid of steel cables was laid out in a twisting hyperbolic paraboloid surface, then coated in a layer of mud — the same material Wallmakers has long treated as a primary architectural medium. The mud isn’t decorative. It provides the compressive strength that stabilises the entire bridge and acts as a barrier against the pests that typically undermine thatched construction.

Designer: Wallmakers

And then there’s the skin. The outer layer is local grass thatch, applied in overlapping scales that give the structure a texture closer to a living creature than a building. The resemblance to a pangolin is intentional. “Thatched roof construction, even though sustainable and thermally efficient, has been on the decline due to problems like pest invasion, lack of skilled labour, deforestation, and the hassle of constant reapplication,” Daniel noted. The mud-thatch composite here attempts to address exactly those failures — rethinking the material from the inside out rather than simply reviving a tradition.

Getting materials to the site was its own challenge. The remote location in Karjat pushed the team toward using what was available locally, which ultimately shaped the entire material palette. The result is a building that feels pulled from the landscape rather than dropped into it. Translucent screens and raw mud surfaces define the interiors, keeping the atmosphere spare and tactile. The design team — Preksha Shah and Ramika Gupta — worked within tight constraints that only tightened the design thinking.

Bridge House is the kind of project that makes the site’s difficulties readable in the finished form. The gorge isn’t hidden; it’s the reason the house exists at all. That honesty — structural, material, spatial — is what makes Wallmakers’ work consistently worth paying attention to.

Helsinki’s Kruunuvuori Bridge Is One of the World’s Longest Car-Free Crossings

Posted on by

Crowd of people walking along a curved waterfront bridge over a wide river, with a cable-stayed bridge in the background under a blue sky.

After more than a decade in the making, Helsinki’s Kruunuvuori Bridge has officially opened, and it’s unlike almost anything else built at this scale. Designed by engineering firm WSP Finland and London-based Knight Architects, the 1,191-metre crossing is now Finland’s longest and tallest bridge, and one of the longest in the world, built exclusively for pedestrians, cyclists, and public transport. There’s not a car lane in sight.

The story begins in 2012, when the City of Helsinki launched an international design competition titled “Kruunusillat” or “Crown Bridges.” Out of 52 entries, the WSP and Knight Architects collaboration, under the project name Gemma Regalis, emerged as the winner in 2013. Thirteen years later, that vision is now a physical reality, reshaping the way Helsinki’s inner city is experienced.

Designer: WSP & Knight Architects

The bridge links the waterside residential area of Kruunuvuorenranta to the Nihti district via Korkeasaari island, pulling thousands of residents meaningfully closer to the city centre. Its defining feature is a slender, 135-metre-tall concrete diamond pylon at its centre, flanked by two 260-metre cable-stayed spans. When illuminated, the pylon is visible from across the city, its facade lighting shifting with the time of day and the season, a deliberate addition to Helsinki’s skyline.

The design team’s priorities went well beyond engineering. WSP lead designer Sami Niemelä noted that the team considered “pedestrian and cyclist safety, a comfortable travel experience, and barrier-free accessibility” from the outset. The bridge’s gentle curve was an intentional choice — a winding path lets users visually track where they’re headed, making the crossing feel more intuitive. Lighting was carefully calibrated to minimise light pollution while still ensuring safety after dark, directing light precisely onto walking and cycling surfaces without excessive glare.

Finnish winters were also factored into the structure. The steel cables were engineered with solutions to prevent snow and ice accumulation, a non-negotiable in this climate. With a design life of 200 years, this is a bridge built to outlast generations. The bridge opened to pedestrians and cyclists on April 18, 2026, with more than 50,000 visitors crossing it during the opening weekend alone.

Construction was carried out by YIT and Kreate under the TYL Kruunusillat consortium, with Knight Architects involved from the earliest concept sketches all the way through to completion. The next chapter begins in early 2027, when tram services are scheduled to activate across the bridge, the final piece in making this crossing a fully operational transit corridor for Helsinki.

The G Clef Bridge In China Is Inspired By Musical Notation & Features A Spiralling Viewpoint

Posted on by

Designed by Chinese studio ZZHK, the G Clef Bridge is a pedestrian walkway spanning across the Bailu River in Chengdu. It forms a spiraling ramp and serves as a viewpoint inspired by musical notation. The G Clef Bridge serves as a link between the French-style town Bailu and the Diamond Music Hall on the opposite river bank. Since the area is a popular music destination, ZZHK used the music reference to influence the design of the bridge.

Designer: ZZHK

“Bailu Music Town lacked a central landmark embodying its theme,” said studio founder Zhang Ke. “We aimed to create a landmark and a spiritual fortress.” “Fulfilling the basic traffic function was essential, but resolving the stylistic conflict between the two banks and enhancing the musical theme of the scenic area were higher objectives,” he concluded.

The star feature of the bridge is a spiralling lamp which is located on the river’s eastern bank. It is shaped like a treble clef. This serves as a space to pass through, and to spend some time in. The spiral provides lush views of the surrounding landscape, as well as of the circular stage located at its base. This stage is intended for music performances.

This stage is surrounded by a shallow pool of water, which is separate from the river. This water body creates the impression that the stage is floating on the river”. The most crucial design approach was ensuring ‘flow’,” said Ke. “Maintaining an overall smoothness in form, achieving seamless integration with the surrounding environment and existing buildings, and harmonizing the tangible structure with its reflection in water.”

A raised section of the bridge is connected to the main spiral, and it takes you above a road to a plaza in the town. The longest portion of the bridge takes you across the river to a promenade right in front of the Diamond Music Hall. The G Clef Bridge is an artful and simple collection of steel columns and box girders, which mimic the form of the music hall, calling attention to its sculptural form.

Revolutionary Cross-Sea Tunnel & Bridge System In China Has Broken 10 World Records

Posted on by

Last month China opened the Shenzhen-Zhongshan Link – a newly built cross-sea tunnel and bridge system in the Guangdong Province, South China. The impressive architectural wonder broke 10 world records, although pretty specific ones! The Pearl River estuary is where the Pearl River joins the South China Sea, and this is one of the most densely populated places in the world. It includes Hong Kong, Macao, and nine other cities in Guangdong, and they are all separated by large water bodies, which is quite difficult to get around. And the Shenzhen-Zhongshan Link has been built to tackle this issue!

The link measures almost 15 miles and is designed to connect the two cities it is named after. Both cities are situated on opposite banks of the Pearl River Estuary. The link isn’t one whole bridge though, it includes an underwater tunnel in the middle, as well as bridges connecting every island to the city. It features eight lanes allowing speeds up to 100 km/h, and it reduces a two-hour drive to only thirty minutes. The link took seven years to construct, and now it finally opened to traffic on June 30.

The Shenzhen-Zhongshan Link has set 10 new world records according to the China Global Television Network (CGTN) –

  1. Largest span for a fully offshore steel box girder suspension bridge (1,666 m/5,466 ft)
  2. Highest bridge deck (91 m/299 ft)
  3. Highest navigation clearance for a sea bridge
  4. Largest offshore suspension bridge anchor (344,000 m3 /12 million cubic ft of concrete)
  5. Highest wind resistance test speed for a suspension bridge (83.7 m/273.6 ft per second)
  6. Largest steel bridge deck with hot-mix epoxy asphalt paving (378,800 m2 /4 million sq ft)
  7. Longest two-way, eight-lane immersed tube tunnel (5,035 m/16,519 ft)
  8. Widest underwater steel shell-concrete immersed tube tunnel (up to 55.6 m/182.4 ft)
  9. Largest single-volume cast for a steel-shell immersed tube using self-compacting concrete (29,000 m3 /1 million cubic ft per tube section)
  10. Widest repeatedly foldable M-shaped water stop used in the final joint of an immersed tube tunnel (3 m/9.8 ft)

The tunnel section also has innovative safety features such as novel firefighting and smoke exhaust systems. Fourteen robots patrol the tunnel throughout and monitor the pipes and cables to ensure everything is working well. The team of robots also keeps a lookout for car accidents, and if one does occur, they direct traffic using built-in loudspeakers, while also filming the scene, and transmitting it to a remote control center.
