Figure 6H-28. Sidewalk Detour or Diversion (TA-28)
This figure illustrates two examples of a sidewalk detour or diversion. A legend under the figure states that this is Typical Application 28. 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 two examples of a vertical roadway with one lane of traffic in each direction intersecting two horizontal roadways. Black arrows on the vertical roadway indicate that traffic is one lane in each direction. The opposing lanes on the vertical roadway are shown separated by a solid double yellow line. Vertical and horizontal sidewalks identified by thick solid white lines bordered by narrow black lines are shown on both sides of the vertical and horizontal roadways. Crosswalks, shown by parallel narrow solid white lines, are shown crossing all the roadways at all the intersections in this figure.
The first example, on the left side of the page, is identified at the bottom of the figure as SIDEWALK DETOUR. At the bottom of the figure to the right of the right lane and south of the lower horizontal roadway and sidewalk, 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 labeled optional facing northbound traffic. It is shown between the right edge of the northbound travel lane and the adjacent sidewalk. On the sidewalk to the right of the vertical roadway and on the north side of the lower horizontal roadway, an orange and white diagonally striped Type III barricade is shown across the sidewalk with a horizontal rectangular white sign with a black border in front of it. The sign shows the words "SIDEWALK CLOSED" in black above a left-pointing black arrow above the words "CROSS HERE" and is shown facing northbound traffic. A left-pointing arrow on the sidewalk shows the direction of pedestrian travel around the work space. Beyond this barricade, another Type III barricade is shown across the sidewalk with a horizontal rectangular white sign with a black border in front of it facing northbound traffic with the words "SIDEWALK CLOSED" in black. This barricade is shown directly in front of a vertical rectangle with diagonal black and white stripes, denoting a work space, that is shown extending from the right edge of the sidewalk to the right edge of the vertical roadway. On the north side of the work space, another Type III barricade is shown with a Sidewalk Closed sign in front of it facing southbound traffic. Beyond this barricade, another Type III barricade is shown with a Sidewalk Closed Cross Here sign on it with an arrow pointing to the right and facing southbound traffic. A right-pointing arrow on the sidewalk shows the direction of pedestrian travel.
The second example, on the right side of the page, is identified at the bottom of the figure as SIDEWALK DIVERSION. At the bottom of the figure to the right of the right lane and south of the lower horizontal roadway, a Road Work Ahead sign is shown facing northbound traffic. It is shown between the right edge of the northbound travel lane and the adjacent sidewalk. On the sidewalk to the right of the vertical roadway and on the north side of the lower horizontal roadway, two side-by-side orange and white diagonally striped Type III barricades are shown across the sidewalk and extending slightly into the vertical travel lane. These barricades are shown directly in front of a square with diagonal black and white stripes, denoting a work space, that is shown extending from about half way across the sidewalk to the left and slightly onto the northbound travel lane. This section of the vertical roadway shows white horizontal and vertical markings on the outsides of both travel lanes, denoting marked parking spaces. The lines at the ends of the parking spaces are shown as L-shaped and in between as T-shaped. The work space is shown extending into the parking spaces on the right side of the northbound travel lane. A series of Type III barricades is shown beginning at the edge of the northbound travel lane just north of the sidewalk on the north side of the lower horizontal roadway. They are shown angling to the left into the roadway on the left side of the work space, then running vertically next to the work space, and then angling back to the right edge of the travel lane to the south of the south sidewalk at the upper horizontal roadway. These barricades are shown at a dimensioned distance of 36 inches MIN. from the left side of the work space. A narrow black line with arrowheads is shown at each end running along the travel path defined by the work space and the adjacent Type III barricades.
