Long Description: Detour Installation and Removal

This figure illustrates an example of a detour for a closed street. 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 refers to tables in the Manual on Uniform Traffic Control Devices.

This figure shows two vertical two-lane roadways intersecting two horizontal two-lane roadways. The vertical roadway on the right is denoted as Main Street. All of the roadways are shown as having two lanes with a broken yellow line between the intersections. Black arrows show the direction of traffic flow as one lane in each direction.

At the bottom of the figure and to the right of the right lane of the rightmost vertical roadway, a symbol denotes the placement of a sign. The sign reads "ROAD CLOSED AHEAD." Beyond this sign at a dimensioned distance B, a sign that reads "DETOUR AHEAD" is shown to the right of the roadway. This sign is shown at a dimensioned distance A in advance of the intersection with the lower horizontal roadway. On the north side of this intersection, an orange and white striped Type III barricade is shown extending across both lanes of Main Street. Attached to the barricade, a sign that reads "ROAD CLOSED" is positioned above a horizontal rectangular DETOUR arrow sign, pointing to the left. Directly behind the barricade is a symbol denoting the location of the work space. The work space is positioned across both lanes of Main Street. On the north side of the work space, another Type III barricade is shown with a sign that reads "ROAD CLOSED" in black attached to it and facing the southbound traffic on Main Street. Farther north on Main Street, two more Type III barricades are shown blocking Main Street. One is shown across the northbound lane of Main Street and is staggered below the second barricade. The second barricade is shown on the south side of the intersection with the upper horizontal roadway across the southbound lane and is shown with a sign assembly attached to it facing the southbound traffic on Main Street. The assembly is composed of a horizontal rectangular sign that reads "ROAD CLOSED TO THRU TRAFFIC" above a DETOUR arrow sign that points to the right. On Main Street, on the north side of the intersection with the upper horizontal roadway, a sign is shown that reads "END DETOUR" faces northbound traffic. To the right of the southbound lane of Main Street, north of the intersection with the upper horizontal roadway, two signs are shown facing southbound traffic on Main Street. One is shown as a "ROAD CLOSED AHEAD" sign. Beyond it at a dimensioned distance B, a "DETOUR AHEAD" sign is shown. This sign is shown at a dimensioned distance A in advance of the intersection with the upper horizontal roadway.

On the upper horizontal roadway, west of the intersection with Main Street, a sign assembly is shown facing eastbound traffic. The signs read "MAIN ST" on one panel above a sign with that reads "DETOUR" and a black left-pointing arrow. On the east side of the intersection of the upper horizontal roadway with the leftmost vertical roadway, another Main St Detour sign assembly is shown with a left-pointing arrow facing westbound traffic.

On the leftmost vertical roadway, south of the intersection with the upper horizontal roadway, another Main St Detour sign is shown with a right-pointing arrow facing northbound traffic. On this same vertical roadway, north of the intersection with the lower horizontal roadway, another Main St Detour sign is shown with a left-pointing arrow facing southbound traffic.

On the lower horizontal roadway, east of the leftmost vertical roadway, another Main St Detour sign is shown with a right-pointing arrow facing westbound traffic. Farther east on the lower horizontal roadway, at the intersection with Main Street, another Main St Detour sign is shown with a right-pointing arrow facing eastbound traffic.

To the right of the southbound lane of Main Street south of the lower horizontal roadway, an End Detour sign is shown.

One large red arrow is located at the upper left of the diagram and is pointing south, indicating that installation of the detour should proceed from north to south. A large red arrow located and the lower left of the diagram is pointing north, indicating that the break down of the detour should proceed from south to north.
