Watch the video on the lateral slide-in technology that is being used to replace the Bearcamp River Bridges.
Accelerated Bridge Construction
The bridges are being replaced by using the Accelerated Bridge Construction (ABC) method known as Lateral Slide-in Construction. Lateral slide-in bridge technology is one of the many tools in the ABC toolbox.
Although this technique in not new, it is being use more often to rapidly replace a bridge and limit impacts to the traveling public. The replacement of each bridge will require short-term lane closures to progress construction activities. Then, each bridge will require a complete closure spanning a a few days only.
The video on this page explains how the lateral slide-in technique will be done.
