A. The Town Engineer is authorized to establish reduced speed limits within construction zones. In accordance with the most recently adopted edition of the Manual on Uniform Traffic Control Devices (MUTCD) and/or sound engineering practices, the reduced speed limits shall be implemented when the Town Engineer determines that the permanent speed limit set for that roadway under construction is not reasonable or safe under the existing conditions.

B. Any reduced speed limit established by the Town Engineer shall be effective only for the duration of the roadway construction. Construction shall mean any road work by the Town or any contractor or subcontractor performing such construction, reconstruction, or maintenance at the direction of the Town.

C. The reduced speed limits shall become effective when the regulatory speed limit signs (black text on white background stating the speed limit) have been erected upon or around the construction zone in a clear visible manner, and the permanent speed limit signs are covered or otherwise not visible to motorists.

D. The traffic control devices, indicating that double civil penalties will be imposed for exceeding the speed limit in a construction zone, shall be posted at least one thousand (1,000) feet before entering the temporary construction zone indicating the beginning of the construction zone and shall be posted to indicate the end of the construction zone. In addition, such traffic control devices shall be posted at least every twenty-five hundred (2,500) feet within the construction zone.

E. It shall be unlawful for a person to drive in a construction zone at a speed greater than the speed posted for that zone. Violations of the construction zone speed limit are subject to double fines under Oro Valley Town Code Section 11-3-3 when workers are present. ((O)12-13, 09/19/2012)
