DEFINITIONS:
<br />Regulatory Speed (in Work Zones)
<br />The maximum permitted travel speed posted for the work zone is
<br />Indicated by the regulatory speed limit signs. The work zone speed
<br />must be shown or noted in the plans. This speed should be used
<br />as the minimum design speed to determine runout lengths, departure
<br />rates, flare rales, lengths of need, clear zone widths, taper lengths,
<br />crash cushion requirements, marker spacings, superelevation and
<br />other similar features.
<br />Advisory Speed
<br />The maximum recommended travel speed through a curve or a hazardous area.
<br />Travel Way
<br />The portion of the roadway for the movement of vehicles. For traffic
<br />control through work zones, travel way may include the temporary use
<br />of shoulders and any other permanent or temporary surface intended
<br />for use as a lane for the movement of vehicular traffic.
<br />a. Travel Lane: The designated widths of roadway pavement marked to
<br />carry through traffic and to separate it from opposing traffic or
<br />traffic occupying other traffic lanes.
<br />b. Auxiliary Lane: The designated widths of roadway pavement marked
<br />to separate speed change, turning, passing and climbing maneuvers
<br />from through traffic.
<br />Detour, Lane Shift, and Diversion
<br />A detour is the redirection of traffic onto another roadway to bypass the
<br />temporary traffic control zone. A lane shift is the redirection of traffic
<br />onto a different section of the permanent pavement. A diversion is the
<br />redirection of traffic onto a temporary roadway, usually adjacent to the
<br />permanent roadway and within the limits of the right of way.
<br />Aboveground Hazard
<br />An aboveground hazard is any object, material or equipment other than
<br />traffic control devices that encroaches upon the travel way or that is
<br />located within the clear zone which does not meet the Department's
<br />safety criteria, i.e., anything that is greater than 4" in height and is
<br />firm and unyielding or doesn't meet breakaway requirements.
<br />TEMPORARY TRAFPle--CONTROL DEVICES:
<br />1. All temporary traffic control devices shall be ON the Department's Approved
<br />Products List (APL). Ensure the appropriate APL number is permanently
<br />marked on the device in a readily -visible location.
<br />2. All temporary traffic control devices shall be removed as soon as practical
<br />when they are no longer needed. When work is suspended for short periods
<br />of time, temporary traffic control devices that are no longer appropriate
<br />shall be removed or covered. Do not store temporary traffic control devices
<br />on the shoulder, sidewalk, or other roadway facility not affected by the
<br />work when work is suspended.
<br />3. Arrow Boards, Portable Changeable Message Signs, Radar Speed Display
<br />Trailer, Portable Regulatory Signs, and any other trailer mounted device
<br />shall be delineated with a channellzing device placed at each corner when
<br />in use and shall be moved outside the travel way and clear zone or be
<br />shielded by a barrier or crash cushion when not in use.

<br />OVERHEAD WORK:
<br />Work is only allowed over a traffic lane when one of the following options is used:
<br />OPTION I (OVERHEAD WORK USING A MODIFIED LANE CLOSURE)
<br />Overhead work using a modified lane closure is allowed if all of the following
<br />conditions are met:
<br />a. Work operation is located in a signalized intersection and
<br />limited to signals, signs, lighting and utilities.
<br />b. Work operations are 60 minutes or less.
<br />c. Speed limit is 45 mph or less.
<br />d. Aerial lift equipment in the work area has hfgh-intensity. rotating,
<br />flashing, oscillating, or strobe lights operating.
<br />e. Aerial lift equipment is placed directly below the work area to close the lane.
<br />I. Traffic control devices are placed in advance of the vehicle/equipment closing
<br />the lane using a minimum ]00 foot taper.
<br />g. Volume or complexity of the roadway may dictate additional devices, signs,
<br />flagmen and/or a traffic control officer.
<br />OPTION 2 (OVERHEAD WORK ABOVE AN OPEN TRAFFIC LANE)
<br />Overhead work above a open traffic lane is allowed if all of the following conditions
<br />are met
<br />a. Work operation is located on a utility pole, light pole, signal pole, or their
<br />appurtenances.
<br />b. Work operations are 60 minutes or less.
<br />c. Speed limit is 45 mph or less.
<br />d. No encroachment by any part of the work activities and equipment within an
<br />area bounded by 2 feet outside the edge of travel way and 18 feet high.
<br />e. Aerial lift equipment in the work area has high-intensity, rotating, flashing,
<br />oscillating, or strobe lights operating.
<br />I. Volume or complexity of the roadway may dictate additional devices, signs,
<br />flagmen and/or a traffic control officer.
<br />g. Adequate precautions are taken to prevent parts, tools, equipment and other
<br />objects from falling into open lanes of traffic.
<br />h. Other Governmental Agencies, Rail facilities, or Codes may require a greater
<br />clearance. The greater clearance required prevails as the rule.
<br />OPTION 3 (OVERHEAD WORK ADJACENT TO AN OPEN TRAFFIC LANE)
<br />Overhead work adjacent to an open traffic lane is allowed if all of the following
<br />conditions are met:
<br />a. Work operation is located on a utility pole, light pole, signal pole, or their
<br />appurtenances.
<br />b. Work operations are 1 day or less.
<br />c. Speed limit is 45 mph or less.
<br />d. No encroachment by any part of the work activities and equipment within 2
<br />foot from the edge of travel way up to 18' height. Above 18' in height, no
<br />encroachment by any part of the -work activities and equipment over the open
<br />traffic lane (except as allowed In Option 2 for work operations of 60 minutes
<br />or less).
<br />e. Aerial lift equipment in the work area has high-intensity, rotating, flashing,
<br />oscillating, or strobe lights operating.
<br />I. Volume or complexity of the roadway may dictate additional devices, signs,
<br />flagmen and/or a traffic control officer.
<br />g. Adequate precautions are taken to prevent parts, tools, equipment and other
<br />objects from falling into open lanes of traffic.
<br />h. Other Governmental Agencies, Rail facilities, or Codes may require a greater
<br />clearance. The greater clearance required prevails as the rule.
<br />OVERHEAD WORK: (Cont.)
<br />OPTION 4 (OVERHEAD WORK MAINTAINING TRAFFIC WITH NO
<br />ENCROACHMENT BELOW THE OVERHEAD WORK AREA)
<br />Traffic shall be detoured, shifted, diverted or paced as to not encroach In the
<br />area directly below the overhead work operations in accordance with the
<br />appropriate index drawing or detailed in the plans. This option applies
<br />to, but not limited to, the following construction activities:
<br />a. Beam, girder, segment, and bent/pier cap placement.
<br />b. Form and falsework placement and removal.
<br />c. Concrete placement.
<br />d. Railing construction located at edge of deck.
<br />e. Structure demolition.
<br />OPTION 5 (CONDUCTOR/CABLE PULLING ABOVE AN OPEN TRAFFIC LANE)
<br />Overhead cable and/or de -energized conductor installations initial pull to proper
<br />tension shall be done In accordance with the appropriate Index or
<br />temporary traffic control plan.
<br />Continuous 'pulling operations of secured cable and/or conductors are allowed
<br />over open lane(s) of traffic with no encroachment by any part of the work
<br />activities, materials or equipment within the minimal vertical clearance above
<br />the travel way. The utility shall take precautions to ensure that pull ropes and
<br />conductors/cables at no time fall below the minimum vertical clearance.
<br />On Limited Access facilities, a site specific temporary traffic control plan is
<br />required. The temporary traffic control plan shall include:
<br />a. The temporary traffic control set up for the initial pulling of the pull
<br />rope across the roadway.
<br />b. During pulling operations, advance warning consisting of no less than a
<br />Changeable Message Sign upstream of the work area with alternating
<br />messages, "Overhead Work Ahead" and "Be Prepared to Stop" followed
<br />by a traffic control officer and police vehicle with blue lights flashing
<br />during the pulling operation.
<br />RAILROADS:
<br />Railroad crossings affected. by a construction project should be evaluated for
<br />traffic controls to reduce queuing on the tracks. The evaluation should include
<br />as a minimum: traffic volumes, distance from the tracks to the intersections,
<br />lane closure or taper locations, signal timing, etc.
<br />SIGHT DISTANCE:
<br />1. Tapers: Transition tapers should be obvious to drivers. If restricted sight
<br />distance is a problem (e.g., a sharp vertical or horizontal curve), the taper
<br />should begin well in advance of the view obstruction. The beginning of
<br />tapers should not be hidden behind curves.
<br />2. Intersections: Traffic control devices at Intersections must provide sight
<br />distances for the road user to perceive potential conflicts and to traverse
<br />the intersection safely. Construction equipment and materials shall not
<br />restrict Intersection sight distance.
<br />ABOVEGROUND HAZARD:
<br />1. Aboveground hazards (see definitions) are to be considered work areas
<br />during working hours and treated with appropriate work zone traffic
<br />control procedures. During nonworking hours, all objects, materials and
<br />equipment that constitute an aboveground hazard must be stored/placed
<br />outside the travel way and clear zone or be shielded by a barrier or
<br />crash cushion.
<br />2. For aboveground hazards within a work zone the clear zone required
<br />should be based on the regulatory speed posted during construction.
