Page 644 2009 Edition <br /> Notes for Figure 614-6—Typical Application 6 <br /> Shoulder Work with Minor Encroachment <br /> Guidance: <br /> 1. All lanes should be a minimum of 10 feet in width as measured to the near face of the channelizing <br /> devices. <br /> 2. The treatment shown should be used on a minor road having low speeds. For higher-speed traffic <br /> conditions, a lane closure should be used. <br /> Option: <br /> 3. For short-term use on low-volume,low-speed roadways with vehicular traffic that does not include longer <br /> and wider heavy commercial vehicles,a minimum lane width of 9 feet may be used. <br /> 4. Where the opposite shoulder is suitable for carrying vehicular traffic and of adequate width,lanes may be <br /> shifted by use of closely-spaced channelizing devices,provided that the minimum lane width of 10 feet is <br /> maintained. <br /> 5. Additional advance warning may be appropriate,such as a ROAD NARROWS sign. <br /> 6. Temporary traffic barriers may be used along the work space. <br /> 7. The shadow vehicle may be omitted if a taper and channelizing devices are used. <br /> 8. A truck-mounted attenuator may be used on the shadow vehicle. <br /> 9. For short-duration work,the taper and channelizing devices may be omitted if a shadow vehicle with <br /> activated high-intensity rotating,flashing,oscillating,or strobe lights is used. <br /> 10. Vehicle hazard warning signals may be used to supplement high-intensity rotating, flashing,oscillating,or <br /> strobe lights. <br /> Standard: <br /> 11. Vehicle-mounted signs shall be mounted in a manner such that they are not obscured by equipment <br /> or supplies. Sign legends on vehicle-mounted signs shall be covered or turned from view when work <br /> is not in progress. <br /> 12. Shadow and work vehicles shall display high-intensity rotating,flashing,oscillating,or strobe lights. <br /> 13. Vehicle hazard warning signals shall not be used instead of the vehicle's high-intensity rotating, <br /> flashing,oscillating,or strobe lights. <br /> Sect.6H.01 December 2009 <br />
