Figure 9C-8. Example of Obstruction Pavement Marking
This figure illustrates an example of obstruction pavement marking.
The figure shows a section of a horizontal roadway. A black arrow shows that the direction of bicycle travel is from right to left. At the top left side of the figure, a square obstruction is shown occupying most of the top half of the pavement width and is labeled a "pier, abutment, grate, or other obstruction."
To the right and in advance of the obstruction, a wide solid white line is shown marked on the pavement. A note states "See Section 3A.06." The solid white line is shown slanting from the top edge of the pavement on the right to the lower edge of the obstruction on the left. The horizontal length of the white line is labeled "L," and the dimension from the top edge of the pavement to the lowest edge of the obstruction is labeled "W."
A note states:
For metric units: L = 0.6 WS, where S is bicycle approach speed in kilometers per hour.
For English units: L = WS, where S is bicycle approach speed in miles per hour.
