The invention provides a road structure. The road structure comprises an entrance lane driving to an intersection and a main signal lamp located at the intersection. The entrance lane comprises a straight lane and a first left turn lane adjacently arranged on the left side of the straight lane; the main signal lamp comprises a main straight signal lamp and a main left-turn signal lamp; a straight vehicle lane changing port is arranged between the straight lane and the adjacent first left-turn lane, and is used for allowing straight vehicles on the straight lane to change lanes and enter the first left-turn lane; a first lane changing signal lamp is arranged at the direct driving lane changing port; the first left turn lane is provided with a first stop line giving way to lane changing vehicles, and the first stop line is provided with an auxiliary signal lamp used for controlling left turn vehicles. According to the invention, the straight lane changing port is additionally arranged between the straight lane and the adjacent left-turn lane, and the lane changing opportunity of the straight vehicle is controlled by using the first lane changing signal lamp, so that the utilization rate of the left-turn lane is improved, and the passing efficiency of the straight vehicle is improved.
