California MUTCD Page 6G-7 <br /> (FHWA's MUTCD 2003 Revision 1,as amended for use in California) <br /> Option: <br /> A lane width of 2.7 in(9 ft)may be used for short-term stationary work on low-volume, low-speed <br /> roadways when vehicular traffic does not include longer and wider heavy commercial vehicles. <br /> Support: <br /> Figure 6H-6 illustrates a method for handling vehicular traffic where the stationary or short duration <br /> work space encroaches slightly into the traveled way. <br /> Section 6G.09 Work Within the Median <br /> Support: <br /> Chapter 6D and Sections 617.68 and 6G.05 contain additional information regarding the steps to follow <br /> when pedestrian or bicycle facilities are affected by the worksite. <br /> Guidance: <br /> If work in the median of a divided highway is within 4.6 in(15 ft)from the edge of the traveled way for <br /> either direction of travel, TTC should be used through the use of advance warning signs and channelizing <br /> devices. <br /> Section 6G.10 Work Within the Traveled Way of Two-Lane Highways <br /> Support: <br /> Chapter 6D and Sections 6F.68 and 6G.05 contain additional information regarding the steps to follow <br /> when pedestrian or bicycle facilities are affected by the worksite. <br /> Detour signs are used to direct road users onto another roadway. At diversions, road users are directed <br /> onto a temporary roadway or alignment placed within or adjacent to the right-of-way. Typical applications <br /> for detouring or diverting road users on two-lane highways are shown in Figures 6144 6H-7(CA), 6H-8, and <br /> 6H-9. Figure 644 6H-7(CA)illustrates the controls around an area where a section of roadway has been <br /> closed and a diversion has been constructed. Channelizing devices and pavement markings are used to <br /> indicate the transition to the temporary roadway. <br /> Guidance: <br /> When a detour is long, Detour(M4-8,M4-9)signs should be installed to remind and reassure road users <br /> periodically that they are still successfully following the detour. <br /> When an entire roadway is closed,as illustrated in Figure 6H-8,a detour should be provided and road <br /> users should be warned in advance of the closure,which in this example is a closure 16 km(10 mi)from the <br /> intersection. If local road users are allowed to use the roadway up to the closure,the ROAD CLOSED <br /> AHEAD, LOCAL TRAFFIC ONLY sign should be used. The portion of the road open to local road users <br /> should have adequate signing,marking, and delineation. <br /> Detours should be signed so that road users will be able to traverse the entire detour route and back to the <br /> original roadway as shown in Figure 6H-9. <br /> Support: <br /> Techniques for controlling vehicular traffic under one-lane,two-way conditions are described in Section <br /> 6C.10. <br /> Option: <br /> Flaggers may be used as shown in Figure 614 10 6H-10(CA). <br /> STOP/YIELD sign control may be used on roads with low traffic volumes as shown in Figure 6H-11. <br /> A temporary traffic control signal may be used as shown in Figure 614 12 6H-12(CA). <br /> Support: <br /> Refer to CVC 21363 for detour signs. <br /> Section 6G.11 Work Within the Traveled Way of Urban Streets <br /> Support: <br /> Chapter 6D and Sections 617.68 and 6G.05 contain additional information regarding the steps to follow <br /> when pedestrian or bicycle facilities are affected by the worksite. <br /> Chapter 6G—Type of Temporary Traffic Control Zone Activities September 26,2006 <br /> Part 6—Temporary Traffic Control <br />
