London’s Tower Bridge Glass Walkway Opens

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.

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.

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 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.

Super Crane Arrives in New York

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.

China Opens Glass Suspension 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.

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.
