Figure 8B-7. Grade Crossing Pavement Markings

This figure illustrates two examples of grade crossing pavement markings.

A note states: "Refer to Figure 8B-6 for placement."

The first example shows a grade crossing pavement marking symbol. It shows a vertical section of one lane of a roadway with a solid yellow center line. At the bottom of the roadway section, a white transverse line is shown that extends across the lane. It is shown as a dimension of 24 inches wide. Beyond it and in the center of the lane, a white "X" is shown with a white "R" on each side of it. The lines making up the "X" are shown as a dimension of 16 inches wide. The height of each "R" is shown as a dimension of 6 ft. The overall height of the "X" is shown as a dimension of 20 ft. The overall width of the "X," including the "R's," is shown as a dimension of 8 ft and noted: "Width may vary according to lane width." At the top of the roadway section and beyond the "X," another white transverse line is shown. The distance from the far edge of one transverse line to the far edge of the other is shown as a dimensioned distance of 50 ft. The distance from the far edge of the first transverse line to the bottom edge of the "X" is shown as a dimensioned distance of 15 ft. The distance from the top edge of the "X" to the far edge of the second transverse line also is shown as a dimensioned distance of 15 ft.

The second example shows a grade crossing alternative (narrow) pavement marking symbol. It shows a vertical section of one lane of a roadway. At the bottom of the roadway section, a white transverse line is shown that extends across the lane. It is shown as a dimension of 24 inches wide. Beyond it, two white "R's" are shown next to each other. Together, they are shown as a dimension of 3.3 ft wide and 6 ft high. At a dimension of 1.6 ft beyond the "RR," a white "X" is shown marked in the lane. The lines making up the "X" are shown as a dimension of 16 inches wide. The overall width of the "X" is shown as a dimension of 6.6 ft. The height of the "X" is shown as a dimension of 20 ft. At the top of the roadway section and beyond the "X," another white transverse line is shown. The distance from the far edge of one transverse line to the far edge of the other is shown as a dimensioned distance of 60 ft. The distance from the far edge of the first transverse line to the bottom edge of the "X" is shown as a dimensioned distance of 24 ft. The distance from the top edge of the "X" to the far edge of the second transverse line is shown as a dimensioned distance of 16 ft.
