Abstract: A highway marker device is provided for marking the location of an object, such as a culvert, located adjacent to a highway. The marker device is comprised of a coil spring having a first end and a second end, wherein the coil spring is comprised of a plurality of windings around a spring axis. Further, a marker post is connected with the first end of the coil spring, wherein the marker post has a post axis and wherein the post axis is substantially perpendicular to the spring axis. Finally, the marker device is comprised of a mounting mechanism for connecting the device with the object such that the coil spring is substantially restrained from bending about the spring axis.
