Contractor equipment or vehicles shall never be us ed to stop, block, or channelize traffic. The Contractor shall not store material or park equipment withi n 15 feet of the edge of the established travel lanes. Equipment parked overnight betwe en 15 and 30 feet of the edge of the travel lane shall be placed behind positive barriers if feasible, or clearly marked by channelizing devices or other reflective devices. Channelization devices shall include Vertical Panel Markers, Ba rricades, Cones, and Drums. These devices shall be installed and maintained at the spacing determined by the MUTCD through the work area. Channelization devices consisting of barricades or drums, at a maximum spacing of 50 feet, shall be used in guardrail areas when neither the existin g guardrail nor the new guardrail is in place. The Contractor shall maintain existing guardrails and/or barri ers until removal is necessary for construction. The Contractor shall use a tempora ry barrier or appropriate channelizing devices while the guardrails and/or barriers are a bsent. Permanent guardrails and barriers shall be installed as soon as possible to minimize risk to the public. All excavation areas adjacent to the roadway shall be channeliz ed continuously in both directions for the length of t he project in all areas where the centerline strip is not effective in accordance with the latest edition of the MUTCD. Where the roadway is adjacent to an area being excavated, a min imum 2 foot shoulder should be maintained and the effective slope of the earth excav ation beyond the 2 foot shoulder shall not be steeper than a 1½ horizontal to 1 vertica l. The effective slope of rock excavation shall not be steeper than 1 horizontal to 1 vertical beyond the 2 foot shoulder. In the case of cuts over 5 feet deep, a Concrete Barrier or other approved barrier shall be placed between the travel lane and the excavated area. In this instance, travel speeds shall be limited by specific a dvisory signing to 20 miles per hour in all cases. When excavation does not leave sufficie nt usable widths to maintain two-way traffic as provided i n Section 105.4 - Maintenance of W ork, one-lane traffic controlled by a traffic signal or continuous flagging may be co nsidered. Closely spaced vertical panels, drums or other channelizing devices shall be u sed on any of these types of areas that are left exposed for short durations. When paving operations or shoulder grading leave a 3 inch or le ss exposed vertical face at the edge of the traveled way, channelization devices shall b e placed 2 feet outside the edge of the pavement at intervals not exceeding 600 feet and a 48 inch by 48 inch W8-9 Low Shoulder sign shall be placed at a maximum spacing of ½ mil e. When paving 6-155 operations or shoulder grading leave greater than a 3 inch expo sed vertical face at the edge of the traveled way, the Contractor shall place shoulder materi al for a width of at least 4 feet to meet the pavement grade, and place channelizing devices as a bove, before the lane is opened to traffic. A temporary ramp shall be constructed with HMA at the ends of the roadway section paved or milled each day. The use of millings or RAP will not b e allowed, but cold patch may be temporarily utilized until HMA plants are open for the s eason. The maximum ramp change in elevation shall not exceed 4” vertical. For Interstat e Highways or roadways with speed limits equaling or exceeding 50 mph; temporary ramps shal l be constructed at a length of eight feet per inch of transition depth. For roadways with s peed limits less than 50 mph and greater than 25 mph, temporary ramps shall be constructed a t a length of four feet per inch of transition depth. For roadways with speed limits 25 mph or less, temporary ramps shall be constructed at a length of two feet per inch of transi tion depth. Materials, placement, maintenance, and removal shall be incidental to cont ract items. Special Detours and temporary structures, if used, shall meet a pplicable AASHTO standards, including curve radii and grade. 652.3.5 Installation of Traffic Control Devices All traffic co ntrol devices shall be in conformance with NCHRP 350 requirements and installed as per ma nufactures recommendations.

The Contractor shall replace damaged traffic control devices wi th devices of acceptable quality, as directed by the Resident. 652.3.6 Traffic Control The Contr actor shall provide a minimum roadway width of 22 feet for two-way traffic and 11 f eet for one-way traffic. The existing travel way width shall be maintained to the maximum extent practical. Vertical panel markers, drums, cones, or striping shall be used to clearly delineate the roadway through the construction area. Two- way traffic operation shall be provided at all times that the C ontractor is not working on the project. One-way traffic sha ll be controlled through work area s by flaggers, utilizing radios, field telephones, or other means of direct communication. The traffic control devices shall be moved or removed as the wo rk progresses to assure compatibility between the uses of the traffic control devices a nd the traffic flow. Traffic control devices that become unnecessary shall be immediately re moved from use. Pavement markings shall be altered as required to conform to th e existing traffic flow pattern. Repainting of pavement marking line, if required to m aintain the effectiveness of the line, shall be considered maintenance of traffic control de vices. No separate payment will be made. Inappropriate existing pavement markings shall b e removed whenever traffic is rerouted, and temporary construction pavement markings shall be placed. Obliteration and removal of non-applicable markings and placement of tempora ry construction pavement markings shall be considered maintenance of traffic control dev ices and will be paid for under the appropriate Contract item. Traffic changes shall not be made unless there is sufficient time, equipment, materials, and personnel available to complete the change properly before the end of the workday. This provision will no t be required when traffic is rerouted for brief periods dur ing daylight hours and the route can be clearly defined by channelizing devices, or flaggers, or both. 652.4 Flaggers The Contractor shall furnish flaggers as requi red by the TCP or as otherwise specified by the Resident.

While flagging, the flagger should stand either on the shoulder adjacent to the traffic being controlled, or in the closed lane. At a spot obstruction with adequate sight distance, the flagger may stand on the shoulder opposite the closed sections to operate effectively. Under no circumstances shall the flagger stand in the lane being used by moving traffic or have their back to oncoming traffic. The flagger should be clearly visible to approaching traffic at all times and should have a clear escape route. When conditions do not allow for proper approach sight distance of a flagger or storage space for waiting vehicles, additional flaggers shall be used a t the rear of the backlogged traffic or at a point where approaching vehicles have adequate stopping sight distance to the rear of the backlogged traffic. A ll flagger stations shall be signed, even when in close proximity. The signs shall be removed or covered when flagger operations are not in place, even if it is for a very short duration. Flaggers shall be provided as a minimum, a 10 minute break, eve ry 2 hours and a 30 minute or longer lunch period away from the work station.
