Figure 6H-11. Lane Closure on Two-Lane Road with Low Traffic Volumes (TA-11)
This figure illustrates an example of a lane closure on a two-lane road with low traffic volume. A legend under the figure states that this is Typical Application 11. A note states "Note: See Tables 6H-2 and 6H-3 for the meaning of the symbols and/or letter codes used in this figure."
This figure shows a vertical two-lane roadway with one lane of traffic in each direction. Downward-pointing black arrows in the left lane and upward-pointing arrows in the right lane denote the direction of traffic. The opposing lanes are shown separated by a broken yellow line with a solid yellow line adjacent to both lanes in advance of the work space. A shoulder is shown to the right of each travel lane. The shoulders are shown separated from the travel lanes by a solid white line.
At the bottom of the figure and to the right of the northbound shoulder, a black inverted "T" is shown denoting a sign. The sign is shown as a diamond-shaped orange sign with a black border and the words "ROAD WORK AHEAD" in black. A yellow warning light labeled optional is shown mounted above the sign. Beyond the sign, at a dimensioned distance C, a sign assembly is shown to the right of the shoulder. It is shown as composed of a yellow warning light labeled optional mounted above a diamond-shaped orange sign with a black border and the words "ONE LANE ROAD AHEAD" in black, which is mounted above a square orange advisory speed plaque with a black border and the words "XX MPH." in black or its metric alternate "km/h." The XX in the km/h sign is within a black circle. This sign assembly is shown at a dimensioned distance B in advance of a diamond-shaped orange sign with a black border shown to the right of the shoulder. The sign shows a vertical upward-pointing black arrow above a red and white YIELD sign symbol. This sign is shown at a dimensioned distance A in advance of another sign assembly to the right of the shoulder. This sign assembly is shown as composed of a triangular red and white YIELD sign mounted above a horizontal rectangular white supplemental plaque with a black border and the words "TO ONCOMING TRAFFIC" in black. Adjacent to this sign assembly, a row of solid white isosceles triangles is shown across the northbound lane. These triangles, denoting a yield line, are shown pointing toward the direction of travel and are labeled optional with a note to see Section 3B.16. Beyond the sign assembly and yield line at a dimensioned distance of 4.6 m (15 ft), a series of orange squares, denoting channelizing devices, is shown. The devices are shown beginning at the far right edge of the right lane and tapering to the left to the broken yellow line separating the opposing travel lanes for a dimensioned distance of 30 m (100 ft) MAX. A buffer space labeled optional is shown beyond this taper. Beyond the buffer space, an orange and white Type III rail barricade is shown directly in front of a vertical rectangle with diagonal black and white stripes, denoting a work space. For the length of the buffer space and to the left of the work space, a row of channelizing devices is shown along a broken yellow line. Opposite the work space to the left of the southbound shoulder, an orange triangular sign facing northbound traffic is shown with a black arrow curving to the right and then straight ahead. Another buffer space labeled optional is shown beyond the work space in advance of another series of tapering channelizing devices. The channelizing devices are shown tapering from the yellow line at the end of the buffer space back to the right edge of the right lane for a dimensioned distance of 30 m (100 ft) MAX. To the right of the shoulder and at the top of the figure, a horizontal rectangular orange sign labeled optional is shown with a black border and the words "END ROAD WORK" in black.
At the top of the figure and to the right of the shoulder of the southbound lane, a black inverted "T" is shown denoting a diamond-shaped orange sign with a black border and the words "ROAD WORK AHEAD" in black. A yellow warning light labeled optional is shown mounted above it. Beyond the sign, at a dimensioned distance C, a sign assembly is shown to the right of the shoulder. It is shown as composed of a yellow warning light labeled optional mounted above an orange diamond-shaped sign with a black border and the words "ONE LANE ROAD AHEAD" in black, which is mounted above a square-shaped orange advisory speed plaque with a black border and the words "XX MPH." or its metric alternate "km/h" in black. The "XX" in the km/h sign is within a black circle. This sign assembly is shown at a dimensioned distance B in advance of the last channelizing device of the ending taper in the northbound lane beyond the work space. At the bottom of the figure facing southbound traffic, a horizontal rectangular orange sign labeled optional is shown with a black border and the words "END ROAD WORK" in black.
