This mark is NOT on the 104th Avenue/Willow Springs Road bridge; no need to go up there! This bridge is a smaller one over the I&M Canal, below the 'big bridge'. This is in the area of the Willow Springs Metra commuter parking area as well as the trailhead & parking for the I&M Trail (Husar Trail). The mark is only about the size of a silver dollar. It is located at the NW end of the northern sidewalk of the bridge. If there was any type of stamping in the middle of the mark, it appears to be worn away.
