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