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 about to begin on the first project in Vermont to use lateral slide construction. The project will build two new bridges over interstate 91 near Burlington, Vermont. The two bridges will be constructed adjacent to the existing bridges and then will be slid into their proper place to finish the project. This relatively new construction method is becoming increasingly popular in highway construction, and the record was recently set for the world’s longest truss slide.
