Section 6G.06 - Work Outside of the Shoulder

01 (DE Revision) When work is being performed off the roadway (beyond the shoulders, but within the right-of-way), little or no TTC might be needed. TTC generally is not needed where work is confined to an area 10 feet or more from the edge of the traveled way. However, TTC is appropriate where distracting situations exist, such as vehicles parked on the shoulder, vehicles accessing the worksite via the highway, and equipment traveling on or crossing the roadway to perform the work operations (for example, mowing). For work beyond the shoulder, see Figures 6H-1, 6H-1A, 6H-1B, 6H-2, and 6H-5A.

Guidance:

02 Where the situations described in Paragraph 1 exist, a single warning sign, such as ROAD WORK AHEAD (W20-1), should be used. If the equipment travels on the roadway, the equipment should be equipped with appropriate flags, high-intensity rotating, flashing, oscillating, or strobe lights, and/or a SLOW MOVING VEHICLE (W21-4) sign.

Option:

03 (DE Revision) If work vehicles are on the shoulder, a SHOULDER CLOSED (W21-5a) sign may be used. For mowing operations, the signs MOWING AHEAD (W21-8) and END MOWING (G20-2-DE) may be used.

04 (DE Revision) Where the activity is spread out over a distance of more than 2 miles, the SHOULDER CLOSED (W21-5a) sign may be repeated every 1 mile.

05 A supplementary plaque with the message NEXT XX MILES (W7-3aP) may be used.

Guidance:

06 A general warning sign like ROAD MACHINERY AHEAD (W21-3) should be used if workers and equipment must occasionally move onto the shoulder.
