California MUTCD 2014 Edition Page 1157 <br /> (FHWA's MUTCD 2009 Edition,including Revisions 1 &2,as amended for use in California) <br /> Notes for Figure M l 6H-10(CA) and 6H-10A(CA) —Typical Application 10 <br /> Lane Closure on a Two-Lane Road Using Flaggers <br /> Option: <br /> 1. For low-volume (Refer to Part 5, Section 5A.01) situations with short work zones on straight roadways <br /> where the flagger is visible to road users approaching from both directions, a single flagger, positioned to be <br /> visible to road users approaching from both directions, may be used (see Chapter 6E). <br /> 2. The ROAD WORK AHEAD and the END ROAD WORK signs may be omitted for short-duration <br /> operations. <br /> .3. Flashing warning lights and/or flags may be used to call attention to the advance warning signs. <br /> A BE PREPARED TO STOP sign may be added to the sign series. <br /> Guidance: <br /> 4. The buffer space should be extended so that the two-way traffic taper is placed before a horizontal(or crest <br /> vertical)curve to provide adequate sight distance for the Bagger and a queue of stopped vehicles. <br /> Standard: <br /> 5.At night,flagger stations shall be illuminated,except in emergencies. <br /> Guidance: <br /> 6. When used, the BE PREPARED TO STOP sign should be located between after the Flagger sign and the I <br /> ONELANEROAD sign. <br /> 7. When a grade crossing exists within or upstream of the transition area and it is anticipated that queues <br /> resulting from the lane closure might extend through the grade crossing, the TTC zone should be extended <br /> so that the transition area precedes the grade crossing. <br /> 8. When a grade crossing equipped with active warning devices exists within the activity area,provisions <br /> should be made for keeping Baggers informed as to the activation status of these warning devices. <br /> 9. When a grade crossing exists within the activity area, drivers operating on the left-hand side of the normal <br /> centerline should be provided with comparable warning devices as for drivers operating on the right-hand <br /> side of the normal center line. <br /> 10.Early coordination with the railroad company or light rail transit agency should occur before work starts. <br /> Option: <br /> 11.A flagger or a uniformed law enforcement officer may be used at the grade crossing to minimize the <br /> probability that vehicles are stopped within 15 feet of the grade crossing, measured from both sides of the <br /> outside rails. <br /> Support: <br /> 12. For State highways, see Caltrans'Standard Plan T13. See Section 1A.11 for information regarding this publication. <br /> 13. If portable transverse rumble strips are used for flagging operations, refer to Section 6F.87. <br /> Chapter 6H—Typical Applications November 7,2014 <br /> Part 6—Temporary Traffic Control <br />
