Figure 6H-6. Shoulder Work with Minor Encroachment (TA-6)
This figure illustrates an example of shoulder work with minor encroachment. A legend under the figure states that this is Typical Application 6. A note states "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. 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 shoulder of the right, northbound lane, a black inverted "T" is shown denoting a sign. The sign shown is a diamond-shaped orange sign with a black border and the words "ROAD WORK AHEAD" in black. Beyond the sign, at a dimensioned distance A, a series of orange squares, denoting channelizing devices, is shown. The devices are shown beginning at the far right edge of the shoulder and tapering to the solid white line separating the shoulder and the northbound lane. This distance is shown as a dimensioned distance 1/3 L. A buffer space labeled optional is shown in advance of a work vehicle shown within the shoulder with a truck-mounted attenuator labeled optional. Just beyond the vehicle and on the shoulder, a vertical rectangle is shown with diagonal black and white stripes, denoting a work space. For the length of the buffer space and to the left of the work vehicle and the work space, a row of channelizing devices is shown on the right side of the right lane. They are shown to the left of and parallel with the solid white line separating the shoulder and right lane. Between the channelizing devices adjacent to the work space and the broken yellow line, a dimensioned distance of 10 ft MIN. is shown. At the top of the figure and to the right of the right shoulder, a horizontal rectangular orange sign is shown with a black border and the words "END ROAD WORK" in black.
At the top-left of the figure and to the right of the shoulder of southbound roadway, a black inverted "T" is shown denoting a sign. The sign is another diamond-shaped orange sign with a black border and the words "ROAD WORK AHEAD" in black. It is shown facing approaching southbound traffic and at a dimensioned distance A in advance of the work space on the right, northbound shoulder. Beyond the work space, a horizontal rectangular orange sign is shown with a black border and the words "END ROAD WORK" in black to the right of the shoulder of the southbound roadway. It is shown facing the approaching southbound traffic. This sign is shown opposite the Road Work Ahead sign on the northbound shoulder.
