WORK ZONE TRAFFIC CONTROL project special provisions specify how to manage lane and road closures for interstate/freeway resurfacing. Requirements reference NCDOT Standard Specifications divisions 10, 11, and 12 and outline installation of advance warning signs, lane-closure procedures on shoulder or within travel lanes, and weather/visibility safety constraints. Provisions establish day and time restrictions, allowable pre-staging and flashing sign timing, enforcement presence when available, and rules for reopening lanes and turning off electronic displays. Speed management mandates lawful ordinance-based limits, DSLS continuous display, coordination for changes, and variable speed reduction controls. Connected lane closure devices and work zone presence lighting and sequential flashing warnings are required for nighttime activities.

WORK ZONE TRAFFIC CONTROL FOR INTERSTATE/FREEWAY RESURFACING (02/17/2020) (Rev. 8/3/2023) General Requirements This Provision is intended for interstate / freeway resurfacing projects. In the event the day and time restrictions allow for daytime work activities, the Work Zone Presence Lighting and Sequential Flashing Lights are to be omitted during daylight hours. The Digital Speed Limit Signs and Connected Lane Closure Devices will be required at all times as described below. Maintain traffic in accordance with Divisions 10, 11 and 12 of the NCDOT Standard Specifications and the following provisions: Install Work Zone Advance Warning Signs in accordance with the attached drawing prior to beginning any other work. When personnel and/or equipment are working on the shoulder adjacent to a divided facility and within 10 feet of an open travel lane, close the nearest open travel lane using Standard Drawing No. 1101.02 of the NCDOT Roadway Standard Drawings. When personnel and/or equipment are working within a lane of travel of a divided facility, close the lane using Standard Drawing No. 1101.02 of the NCDOT Roadway Standard Drawings or as directed by the Engineer. Conduct the work so that all personnel and/or equipment remain within the closed travel lane. Perform work only when weather and visibility conditions allow safe operations as directed by the Engineer. 1. Time Restrictions for Lane Closure and Road Closure Activities All lane closure and road closure activities shall be performed in compliance with the day and time restrictions listed and defined in this Contract. Any activities performed outside of these requirements will be subject to the liquidated damages unless approved by the Engineer prior to beginning the activity. The Contractor may place/pre-stage all required signs and traffic control devices necessary for lane closures prior to the closure time as approved by the Engineer. However, flashing arrow boardsand changeable message signs shall not indicate lane closure information until 30 minutes or less prior to the installation of the lane closure. Allowable pre-staging times are 1 hour for a single lane closure and 2 hours for double and triple lane closures. The travel lane(s) are to be closed atthe prescribed times defined in this Contract. When available, law enforcement should be onsite to shadow workers during pre-staging activities. For removal, the lane(s) must be reopened in compliance with the times defined in this Contract. It is acceptable to remove the signs and traffic control devices from the shoulder/staging area after the lane(s) are reopened to traffic. All electronic lane closure messages and flashing arrow displays shall be off once lanes are opened. When available, law enforcement should remain on the project while workers remove and secure their signs and devices. 2. Work Zone Speed Limits and Digital Speed Limit Signs (DSLS) All speed limits are the sole authority of the NCDOT. An ordinance by the State Traffic Engineer is required for all speed limits in order to have a lawfully enforceab

FAQs

What time restrictions apply to lane closure and road closure activities?

All lane and road closure activities must follow the day and time restrictions defined in the contract. Work outside those requirements triggers liquidated damages unless the Engineer approves it before starting.

How are digital speed limit signs (DSLS) managed during lane closures?

Speed limits must follow a lawfully enforceable ordinance from the State Traffic Engineer. The DSLS must continuously display the work zone speed limit, and any changes require coordination and approval by the Engineer before updating.

What devices are required for work zone awareness and communication?

Connected Lane Closure Devices must transmit lane-closure location information to navigational companies and STOC. For nighttime work, Work Zone Presence Lighting and Sequential Flashing Warning Lights are required to alert motorists and support compliance with reduced speed limits.
