On 26th of August 2016, the opening ceremony of the third bridge of Bosporus - known as Yavus Sultan Selim Bridge- took place. The construction had been started in 2013 and the bridge supports four-lane motorway nd one railway line in each direction. It is located in Istanbul and it is a cable-stayed bridge. However, its size exceeds the typical dimensions of this type of bridge.
A new bridge project began last month in Fairfield, Vermont that uses new technology to reduce construction time, save money, and help the Vermont Transportation Agency start more projects that are backlogged across the state. The ‘Bridge in a Backpack’ technology is part of Vermont’s accelerated bridge program that incorporates quick building design and other innovations to speed up the bridge building process. The system was developed at the University of Maine Advanced Structures and Composites Center in response to Tropical Storm Irene that hit the region several years ago. Vermont engineers found themselves unable to quickly repair or replace the many bridges that were damaged by the storm. Rather than taking months to complete a bridge using conventional methods, the ‘Bridge in a Backpack’ technology allows a new bridge to be finished in weeks.
Construction is currently underway on the country’s first multi-modal bridge that bans private cars. Instead of carrying private vehicle traffic, the bridge will carry MAX light rail trains, Portland’s streetcar line, city busses, and pedestrian and bike traffic. The decision to ban cars was made mostly because there is not an existing roadway on either side of the bridge. City planners did not want to ruin the redevelopment occuring along the river by carving it up with a new freeway on both sides. The city looked into having the MAX trains travel on the existing Hawthorne Bridge, but decided against that option despite most likely being cheaper than building a new bridge. The bridge, known as the Tilikum Crossing, is being constructed in Portland, Oregon and will be completed next year. The bridge will open for one day in early August for the 19th annual Providence Bridge Pedal and Stride. It will then close again until its official opening on September 12th.
If anyone is in the market for purchasing an old bridge here is your chance. Multnomah county in Oregon has put the 88-year-old Sellwood Bridge up for sale until September 12th. The bridge is Oregon's only bridge with a four-span continuous truss holding up the roadway and the only known highway bridge nationally with such distinction. Despite not being listed on the register of the National Register of Historic Places, simply qualifying to be on the list is enough to force the county to put the bridge up for sale. The National Historic Preservation Act states that Multnomah county must seek out potential buyers before they can demolish the bridge.
After the success of the Tianmen Mountain Skyway in Zhangjiajie, China, Chinese engineers have opened a new glass suspension bottomed bridge. This time, though, the bridge is only 180 meters above ground level instead of 900 meters like the Tianmen Mountain Skyway. The bridge stretches between two mountain peaks in the Hebei Province and spans 300 meters. It is 2.3 meters wide and is estimated to have cost $42 million.
The “I Lift NY” floating super crane arrived at the Tappan Zee Bridge this week and yesterday had to do the limbo to travel to the other side of the bridge. The crane made its way up the Hudson River from Jersey City on Monday after completing its journey from San Francisco through the Panama Canal earlier this month. Around 5 pm yesterday, a tugboat helped guide the crane north underneath the existing bridge and to the location where the new bridge is currently under construction. Workers on site prepared for the crane's arrival by removing the existing bridge’s navigation light from under the bridge to give the crane a little more clearance. The barge carrying the crane was also filled with water to make it ride lower in the water. The crane was able to squeeze under the existing bridge without any problems and will now be anchored on the other side for the next couple of years. It uses special steel anchors, called spuds that are planted in the river bottom to keep from moving.
The new Tilikum Crossing Bridge in Portland, Oregon began testing its new ambient lighting system last Thursday and Friday. Morgan Barnard, Douglass Hollis, and Anna Valentina Murch designed the LED light system to change colors according to the data streamed from the U.S. Geological Service river monitor near the Tilikum Crossing Bridge. Those living in the area or using the bridge will not only see the light system change colors throughout the day, but they will also witness large changes in color throughout the course of the year as the time of year affects the river’s speed, temperature, and height.
The creators of the Bay Bridge’s “Bay Lights” have until the end of the year to raise $4 million to keep their changing light display from coming to an end. The Bay Lights have been around since March of 2013 and are operating on a two-year permit. The system was privately funded and cost $8 million to install. They are made up of 25,000 LED lights that are attached to 300 cables on one side of the bridge’s western span. Artist Leo Villareal programmed the lights to constantly change patterns from dusk until dawn each night.
The world’s first peak-to-peak suspension bridge opened in Switzerland yesterday. The bridge’s 351-foot span is only 31 inches wide and it is located 9,800 feet above sea level. Anyone brave enough to cross the Peak Walk at Glacier 3000 will take in incredible views of the Swiss Alps including 24 peaks including Mont Blanc and Matterhorn. The ski resort opened this past weekend and the resort’s owners plan to keep the Peak Walk at Glacier 3000 open year round, weather permitting. And the best news of all is it is free for everyone.
London’s Tower Bridge has just joined the Grand Canyon, Willis Tower, and the Eifel Tower by opening a glass walkway 120 feet above the bridge deck. The walkway is the first of two walkways to open over the bridge that will allow visitors to experience vertigo inducing views of the Thames River. The other walkway, over the east side of the bridge, will be opened on December 1.
This summer the world's highest and longest glass-bottom bridge, located in Zhangjiajie, a scenic national park in the country's Hunan province, is going to be completed and it will connect two massive cliffs.
The first phase of the demolition process of the East Span of the San Francisco-Oakland Bay Bridge has been completed. The project, with a final cost $63.7 million, started in November 2013 and finished the current month.
The Jiaozhou Bay Bridge in China, spanning 41.58 km (25.84 mi), holds the Guinness World Record for the longest bridge over water. Completed in 2011, the bridge connects the booming Northern port city of Qingdao with an airport built on a nearby island and the industrial suburb of Huang Dao. The road distance between the two cities is reduced by 30 km (19 mi) shortening the travel time by 20-30 min.
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.
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.
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 Jacques Cartier Bridge, dating back to 1930, is a steel truss cantilever structure over the St Lawrence River in Montreal, Quebec.
