California MUTCD 2014 Edition (FHWA’s MUTCD 2009 Edition, including Revisions 1 & 2, as amended for use in California) Chapter 6G – Type of Temporary Traffic Control Zone Activities November 7, 2014 Part 6 – Temporary Traffic Control Page 1124 04 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 (W21-5a) with distances indicated. The work space on the shoulder should be closed off by a taper or channelizing devices with a length of 1/3 L using the formulas in Tables 6C-3, 6C-3(CA) and 6C-4. 05 When the shoulder is not occupied but work has adversely affected its condition, the LOW SHOULDER (W8- 9) or SOFT SHOULDER (W8-4) sign should be used, as appropriate. 06 Where the condition extends over a distance in excess of 1 mile, the sign should be repeated at 1-mile intervals. Option: 07 In addition, a supplementary plaque bearing the message NEXT XX MILES (W7-3aP) may be used. Temporary traffic barriers may be needed to inhibit encroachment of errant vehicles into the work space and to protect workers. Standard: 08 When used for shoulder work, arrow boards shall operate only in the caution mode. Support: 09 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 6H-4. Work on freeway shoulders is shown in Figure 6H-5 6H- 5(CA). Section 6G.08 Work on the Shoulder with Minor Encroachment Support: 01 Chapter 6D and Sections 6F.74 and 6G.05 contain additional information regarding the steps to follow when pedestrian or bicycle facilities are affected by the worksite. Guidance: 02 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 10 feet, the lane should be closed. 03 Truck off-tracking should be considered when determining whether the minimum lane width of 10 feet is adequate. Option: 04 Except on State highways, a A lane width of 9 feet may be used for short-term stationary work on low-volume, low-speed roadways when vehicular traffic does not include longer and wider heavy commercial vehicles. Support: 05 Figure 6H-6 illustrates a method for handling vehicular traffic where the stationary or short duration work space encroaches slightly into the traveled way. Section 6G.09 Work Within the Median Support: 01 Chapter 6D and Sections 6F.74 and 6G.05 contain additional information regarding the steps to follow when pedestrian or bicycle facilities are affected by the worksite. Guidance: 02 If work in the median of a divided highway is within 15 feet from the edge of the traveled way for either direction of travel, TTC should be used through the use of advance warning signs and channelizing devices. Section 6G.10 Work Within the Traveled Way of a Two-Lane Highway Support: 01 Chapter 6D and Sections 6F.74 and 6G.05 contain additional information regarding the steps to follow when pedestrian or bicycle facilities are affected by the worksite. 02 Detour signs are used to direct road users onto another roadway. At diversions, road users are directed onto a temporary roadway or alignment placed within or adjacent to the right-of-way. Typical applications for detouring
