Figure 3B-10. Examples of Applications of Freeway and Expressway Lane-Drop Markings (Sheet 2 of 5)

This figure illustrates five examples of freeway and expressway lane-drop markings. The figure is composed of five sheets.

Sheet 2 shows a figure labeled "B – Lane drop at a multi-lane exit ramp having an optional exit lane that also carries the through route." A legend shows a black arrow indicating the direction of travel in the lanes.

The figure shows a vertical highway with five lanes of one direction of a divided highway, four lanes of which continue through past an exit ramp, and the rightmost of which angles off to the right to become the exit ramp. Arrows indicate that the direction of travel is from the bottom of the figure to the top. A solid yellow line is shown to the left of the leftmost through lane, a solid white line is shown to the right of the rightmost travel lane, and the through lanes are shown separated from each other by a broken white line.

In the middle of the figure, the far right lane is shown becoming the deceleration lane, leading to a right exit ramp. The deceleration lane is shown separated from the rightmost of the four remaining through lanes by a wide dotted white lane line. It is shown changing to a solid white line in advance of the theoretical gore. It is labeled as a "wide solid white lane line (variable length)." The distance from the beginning of the dotted white lane line to the theoretical gore is shown as a dimension of 1/2 mile MIN, and the distance from the beginning of the solid white lane line to the theoretical gore is shown as a dimension that varies. The exit lane is wide enough that the solid white line is shown separating left and right exit lanes. On the left side of the left exit lane, the white lane line joins the white edge line from the right through lane to become white channelizing lines that then form a white triangle or neutral area in front of the physical gore. This triangle is shown with "optional white chevron markings in the neutral area." The exit ramp angles away to the right, and the solid white line between the two lanes is shown changing to a broken white line. An arrow indicates the direction of travel on the ramp.
