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.
