Thanks to their maintenance-free operation, high durability, and low weight, composites have found their way into transportation infrastructure, from footbridges and inspection walkways to gap covers and railings for motorway bridges. Composite materials are also used in tunneling, mostly in the form of high-load composite covers in the C250 and D400 loading classes. Another advantage, of sorts, is that composite materials are generally not purchased by salvage yards, which means that composite covers are less likely than metal ones to be stolen and leave a hazardous hole in the roadway.
