The smart road will also reduce the cost of pavement and bridge maintenance in the end. In 2007, a ton of liquid asphalt cost $175 and now it is at $1,000 a ton because it is petroleum based. If we rid the nuclear plants and the coal plants, which cost millions to build, that money, can be rolled into the Smart Road.
