These provisions must be adjusted by the Party Chief to fit roadway and traffic conditions when the Survey Work Zone includes intersections. (A) A STAY IN YOUR LANE (MOT -1-06) sign shall be added to the Advance Warning Sign sequence as the second most Immediate sign from the work area. (B) Elevation Surveys -Cones may be used at the discretion of the Party Chief to protect prism holder and flagger(s). Cones, if used, may be placed at up to 50' intervals along the break line throughout the work zone. LAST REVISION 11/01/24 SURVEY WORK ZONES: (Cont.) (C) Horizontal Control -With traffic flow In the same direction, cones shall be used to protect the backslght tripod and/or instrument. Cones shall be placed at the equipment, and up to 50 intervals for at least 20C towards the flow of traffic. (D) Horizontal Control -With traffic flow in opposite directions, cones shall be used to protect the backlight tripod and/or instrument.

INTERSECTING ROAD SIGNING Signing for the control of traffic entering and leaving work zones by way of intersecting crossroads shall be adequate to make drivers aware of work zone conditions. When Work operations exceed 60 minutes, place the ROAD WORK AHEAD sign on the side street entering the work zone. ADJOINING ANDIOR OVERLAPPING WORK ZONE SIGNING Adjoining work zones may not have sufficient spacing for standard placement or signs and other traffic control devices in their advance warning areas or in some cases other areas within their traffic control zones. Where such restraints or conflicts occur or are likely to occur, one of the following methods will be employed to avoid conflicts and prevent conditions that could lead to misunderstanding on the part of the traveling public as to the Intended travel way by the traffic control procedure applied: (A) For scheduled projects the engineer in responsible charge of project design will resolve anticipated work zone conflicts during the development of the project traffic control plan. This may entail revision of plans on preceding projects and coordination of plans on concurrent projects. (B) Unanticipated conflicts arising between adjoining in progress highway construction projects will be resolved by the Resident Engineer for projects under his residency, and, by the District Construction Engineer for in progress projects under adjoining residencies. (C) The District Maintenance Engineer will resolve anticipated and occurring conflicts within scheduled maintenance operations. SIGNS: (Cont.) SIGN COVERING AND INTERMITTENT WORK STOPPAGE SIGNING Existing or temporary traffic control signs that are no longer applicable or are inconsistent with intended travel paths shall be removed or fully covered. Sign blanks or other available coverings must completely cover the existing sign. Rigid sign coverings shall be the same size as the sign it is covering, and bolted In a manner to prevent movement. Sign covers are incidental to work operations and are not paid for separately. SIGNING FOR DETOURS, LANE SHIFTS AND DIVERSIONS Detours should be signed clearly over their entire length so that motorists can easily determine how to return to the original roadway. The reverse curve (WI -4) warning sign should be used for the advanced warning for a lane shift. A diversion should be signed as a lane shift. EXTENDED DISTANCE ADVANCE WARNING SIGN Advance Warning Signs -shall be used at extended distance of one-half mile or more when limited sight distance or the nature of the obstruction may require a motorist to bring their vehicle to a slop. Extended distance Advanced Warning Signs may be required on any type roadway, but particularly be considered on multilane divided highways where vehicle speed is generally In the higher range (45 MPH or more). UTILITY WORK AHEAD SIGN The UTILITY WORK AHEAD (W21-7) sign may be used as an alternate to the ROAD WORK AHEAD or the ROAD WORK XX FT (W20-1) sign for utility operations on or adjacent to a highway. LENGTH OF ROAD WORK SIGN The length of road work sign (G20-1) bearing the legend ROAD WORK NEXT____ MILES is required for all projects of more than 2 miles in length. The number of miles entered should be rounded up to the nearest mile. The sign shall be located at begin construction points. GROOVED PAVEMENT AHEAD SIGN The GROOVED PAVEMENT AHEAD sign is required 500 feet in advance of a milled or grooved surface open to traffic. The W8 -15P placard shall be used in conjunction with the GROOVED PAVEMENT AHEAD sign. END ROAD WORK SIGN The END ROAD WORK sign (620-2) should be installed on all projects, but may be omitted where the work operation is less than I day. The sign should be placed approximately 500 feet beyond the end of a construction or maintenance project unless other distance is called for in the plans. When other Construction or Maintenance Operations occur within 1 mile this sign should be omitted and signing coordinated In accordance with Index 102-600, ADJOINING ANDIOR OVERLAPPING WORK ZONE SIGNING. (D) The Unit Maintenance Engineer will resolve conflicts that occur within routine maintenance works; between routine maintenance work, unscheduled work and/or permitted work; and, between unit controlled maintenance works and highway construction projects.
