California MUTCD Page 6G-6 (FHWA's MUTCD 2003 Revision 1,as amended for use in California) Section 6G.07 Work on the Shoulder with No Encroachment Support: Chapter 6D and Sections 617.68 and 6G.05 contain additional information regarding the steps to follow when pedestrian or bicycle facilities are affected by the worksite. The provisions of this Section apply to short-term through long-term stationary operations. Standard: When paved shoulders having a width of 2.4 in (8 ft)or more are closed,at least one advance warning sign shall be used.In addition,channelizing devices shall be used to close the shoulder in advance to delineate the beginning of the work space and direct motor vehicle traffic to remain within the traveled way. Guidance: When paved shoulders having a width of 2.4 m(8 ft)or more are closed on freeways and expressways, road users should be warned about potential disabled vehicles that cannot get off the traveled way. An initial general warning sign(such as ROAD WORK AHEAD) should be used,followed by a RIGHT or LEFT SHOULDER CLOSED sign. Where the end of the shoulder closure extends beyond the distance which can be perceived by road users, a supplementary plaque bearing the message NEXT X METERS(FEET)or kfn (MILES) should be placed below the SHOULDER CLOSED sign. On multi-lane,divided highways, signs advising of shoulder work or the condition of the shoulder should be placed only on the side of the affected shoulder. When an improved shoulder is closed on a high-speed roadway, it should be treated as a closure of a portion of the road system because road users expect to be able to use it in emergencies.Road users should be given ample advance warning that shoulders are closed for use as refuge areas throughout a specified length of the approaching TTC zone. The sign(s)should read SHOULDER CLOSED with distances indicated. The work space on the shoulder should be closed off by a taper or channelizing devices with a length of 0.33 L using the formulas in Table 6C-3. When the shoulder is not occupied but work has adversely affected its condition,the LOW SHOULDER or SOFT SHOULDER sign should be used,as appropriate. Where the condition extends over a distance in excess of 1.6 km(1 mi), the sign should be repeated at 1.6 km(I mi)intervals. Option: In addition, a supplementary plaque bearing the message NEXT X km(MILES)may be used. Temporary traffic barriers may be needed to inhibit encroachment of errant vehicles into the work space and to protect workers. Standard: When used for shoulder work,arrow panels shall operate only in the caution mode. Support: A typical application for stationary work operations on shoulders is shown in Figure 6H-3. Short duration or mobile work on shoulders is shown in Figure 6H4 6H-4(CA). Work on freeway shoulders is shown in Figure 614 5 6H-5(CA). Section 6G.08 Work on the Shoulder with Minor Encroachment Support: Chapter 6D and Sections 617.68 and 6G.05 contain additional information regarding the steps to follow when pedestrian or bicycle facilities are affected by the worksite. Guidance: When work takes up part of a lane,vehicular traffic volumes,vehicle mix(buses,trucks,cars, and bicycles), speed, and capacity should be analyzed to determine whether the affected lane should be closed. Unless the lane encroachment permits a remaining lane width of 3 in(10 ft),the lane should be closed. Truck off-tracking should be considered when determining whether the minimum lane width of 3 in(10 ft)is adequate.
