Figure 6C-3. Example of a One-Lane, Two-Way Traffic Taper

This figure illustrates an example of a one-lane, two-way traffic taper.

A vertical two-lane roadway is shown, which then is shown curving to the right and then continuing in a straight line, diagonally upward and to the right. A legend shows a black arrow indicating the direction of travel on the roadway lanes, a yellow square denoting a channelizing device, a diagonally striped rectangle denoting a work space, a horizontal red flag denoting a flagger, and a short inverted "T" denoting a sign.

At the bottom of the figure, a black arrow is shown in each lane denoting the direction of travel. One arrow is pointing upward, and another is pointing downward. A shoulder is shown on each side of the roadway, and a solid white line is shown separating each of the shoulders from the adjacent travel lane. A double yellow line is shown separating the two travel lanes.

Starting from the bottom of the figure, traveling upward (northbound) to the right of the shoulder, three upside-down T-shaped symbols representing sign locations are shown equally spaced.

About one-third up from the bottom of the figure, a red flagger symbol is shown on the right shoulder. Where the flagger is located and extending to the start of the roadway's curve to the right, a longitudinal section of the road is shown labeled "One-Lane, Two-Way Traffic Taper" and accompanied by the notation "50 to 100 ft." In this section of the roadway, starting at the white line separating the shoulder from the right lane, a series of orange squares equally spaced denoting channelizing devices are shown tapering in to the double yellow line.

Directly above this area and extending to the end of the curved section of road, a longitudinal section of road is shown that is labeled "Buffer Space (longitudinal) is used to position the taper in advance of the curve." In this area, the orange squares representing channelizing devices are shown to continue along the center of the double yellow line.

Directly above this space, beyond the curve and extending along the subsequent straight section of road, an area is shown labeled "Work Space." In this area, a rectangular black and white diagonally striped box is shown occupying the right lane. The orange squares representing channelizing devices are shown to continue along the center of the double yellow line for a short way above the work space. Adjacent to the work space, a double-headed black arrow is shown in the southbound lane, denoting two-way traffic in that lane.

Directly above this space, along the straight section of road, an area is shown labeled "Buffer Space (longitudinal)." In this area, the orange squares representing channelizing devices are shown to continue along the center of the double yellow line.

Directly beyond this area, along the straight section of road, an area is shown labeled "Downstream Taper 50 to 100 ft." In this section of the roadway, starting at the double yellow line, a series of orange squares equally spaced denoting channelizing devices are shown tapering out to the white line separating the shoulder from the right lane.

Near the top of the figure, a symbol is shown to the right of the northbound shoulder, signifying a sign location.

Starting from the top of the figure and traveling downward (southbound lane) to the right of the shoulder, three symbols representing sign locations are shown equally spaced, the last one opposite the one to the right of the northbound shoulder. About one-fourth from the top of the figure, a red flagger symbol is shown on the shoulder just in advance of the last of the channelizing devices along the northbound white shoulder line. Farther south in the southbound lane and just below the flagger in the northbound shoulder, a symbol is shown to the right of the southbound shoulder, signifying a sign location.
