The Jacques Cartier Bridge, dating back to 1930,   is a steel truss cantilever structure over the St Lawrence River in Montreal, Quebec. Its illumination was the centerpiece of the city’s 375th and Canada’s 150th anniversaries, with 2,800 light fixtures that will light up the lively Old Port every night for the next ten years.  

Last Tuesday, October 17th, the Netherlands inaugurated the world’s first 3D-printed concrete bridge, which is primarily meant to be used by cyclists. The bridge, which crosses a canalized river in the southeastern town of Gemert, is made of 800 layers of reinforced, pre-stressed concrete with a steel cable running through it to handle tensile stress. Constructed in Eindhoven by the Technical University of Eindhoven and the Dutch construction company BAM, it is 8 meters long by 3.5 meters wide and it took around three months to put together, while its life cycle is estimated at 30 years at least. “The bridge is not very big, but it was rolled out by a printer, which makes it unique,” Theo Salet, from the Eindhoven University of Technology. The new bridge is part of the Noord-Om project, a new section of ring road around the village of Gemert linking the existing routes N605 and N272, and hundreds of cyclists are expected to ride over it every day.

The first major combined bridge and tunnel sea-crossing project in China is the Hong Kong-Zhuhai-Macau Bridge project. Consisting of three cable-stayed bridges and one 6-km sea crossing tunnel, it will have a total length of 55 km. It will be the world’s longest sea bridge and will link three cities in China's Pearl River Delta — creating one mega-city of 42 million people and slashing travel time between Hong Kong and Chinese city Zhuhai from three hours to just 30 minutes. 

On Saturday, July 29th, the world’s longest pedestrian suspension bridge opened to the public in Switzerland. Having a length of 1621 feet, a width of just over two-feet and rising as high as 279 feet, the Charles Kuonen Suspension Bridge crosses the valley between the towns of Grächen in the north and Zermatt in the south.
