Abstract: An apparatus is for constructing a guide line for a road. The apparatus includes a painting apparatus part that stores a lane paint, is driven by receiving power, and supplies the lane paint. A nozzle part is installed in the painting apparatus part and sprays the lane paint supplied from the painting apparatus part on a road to form a guide line for a road including at least one of a directional mark and a lane. An adjustment part is installed in the painting apparatus part and adjusts at least one of a location and an interval of the lane paint sprayed from the nozzle part.
