To provide a strut for a road, not easily breaking and effectively absorbing a load by well receiving the load and flexibly tilting.

This strut for a road has: a front flange part 3 and a rear flange part 4 opposed to each other in the longitudinal direction; and a web part 5 for connecting the both front and rear flange parts 3, 4. The front flange part 3 has: a straight part 6; a tilted part 7 tilted from the bottom end 61 of the straight part 6 to the diagonally front lower side through a first bent line L1 formed in the lateral direction of the front flange part 3; and a rising part 8 extending from the bottom end 71 of the tilted part 7 downward through a second bent line L2 formed in the lateral direction. The rear flange part 4 extends vertically straight to be parallel to the straight part 6. The lateral width of the flange part is smaller than that of the front flange part 3.
