Louisiana Revised Statutes Tit. 48, § 279. Night time work on construction and maintenance projects; exceptions

A. On any construction or maintenance project which requires the temporary closure of a lane on a controlled access principal arterial interstate, the department shall perform a traffic queue analysis and where the analysis determines a potential for traffic which may result in undue hardship or significant delay to the motoring public, the department shall ensure that such construction or maintenance work is performed during non-peak traffic hours, including night work between the hours of 8 p.m. and 6 a.m. and weekends, unless specific traffic studies determine that such non-peak hour work is not feasible. For purposes of this Section, peak traffic hours shall be considered 7:00 a.m. to 9:00 a.m. and 4:00 p.m. to 6:00 p.m. on weekdays. On projects where the department has found non-peak work feasible and provides an incentive to construct expeditiously, the contractor shall perform non-peak work or provide just cause for failure to perform non-peak work in order to qualify for or earn the incentive to construct expeditiously.

B. If after reviewing existing traffic volumes, congestion, traffic control measures, motorist safety, project cost, project quality, inspection obligations, highway user costs, work force availability, work zone lighting, worker safety, and other factors which the department may deem necessary in determining the feasibility of non-peak hour construction or maintenance, the department determines that it is not feasible to perform construction or maintenance work during non-peak hours, the secretary shall provide a written report on the feasibility study to be delivered by certified mail to the cochairmen of the Joint Committee on Transportation, Highways, and Public Works including specific details of factors which contributed to the determination. Within forty-five days of receipt of the report, the joint committee may conduct a hearing to review the report. If at the hearing the committee finds the determination of the department unacceptable by a majority vote of the members, then such determination shall be sent to the governor and the department.

C. When the department determines that a construction or maintenance project on a controlled access principal arterial interstate highway will have the potential of causing significant traffic delays or undue hardship to the public using such highway, advance signing shall be posted on the right of way of such highway at a location in advance of the last exit prior to the traffic buildup in order to allow the operator of a vehicle to exit the highway and avoid such buildup. Such signing shall indicate that there is traffic congestion ahead and such exit is the last opportunity for exiting the highway before such congestion.
