Once the roadway is in place, other vehicles in the convoy can move over the previously impassable section of terrain. The aluminum structure can be extended to 50 meters in length and support vehicles weighing up to 70 metric tons. Once everyone is across, the truck rolls everything up again and keeps on moving.
The Trackway can even work in partially submerged conditions, which makes it ideal for operating in disasters areas caused by floods or mudslides. Getting emergency vehicles to cut-off areas is one of the most common problems in these scenarios. Certain kinds of extremely muddy conditions can thwart even the most powerful wheeled or amphibious vehicles.

The Trackway was initially developed by the U.K. Ministry of Defence and, according to the company website, is already in use by more than 30 different military agencies around the world. More recently, the truck is being deployed by humanitarian and disaster relief operations in situations where rapid access to remote areas is needed. In a pinch, the 50 meters of roadway can be unspooled in under six minutes.
