§ 12-4-41 - TEMPORARY CONSTRUCTION ZONE SPEED LIMITS.
(A) The City Traffic Engineer or Designee ("traffic engineer") may set a reduced speed limit for a construction zone for an indefinite period if the traffic engineer determines that a special hazard exists due to the construction that requires a lower speed limit to protect the public safety and welfare.
(B) The traffic engineer must base a determination under this section on an engineering and traffic investigation, in accordance with applicable law.
(C) At the direction of the traffic engineer, traffic control signs, signals, or other devices notifying the public of the reduced speed limit shall be installed on the streets in the construction zone.
(D) On or before the date the traffic engineer installs the signs required by this section, the traffic engineer shall post the temporary construction zone speed limit notice at city hall describing the streets subject to the reduced speed limit for a construction zone. A notice filed under this section must state the effective start date of the reduced speed limit.
(E) Upon determination by the traffic engineer that a special hazard no longer exists due to the construction that requires a lower speed limit to protect the public safety and welfare, the traffic engineer shall post termination of the temporary construction zone limit notice at city hall describing the streets that were subject to the reduced speed limit for a construction zone.
(F) The temporary construction zone speed limits set by the traffic engineer are lawful.
(G) A speed in excess of the temporary construction zone speed limits set by the traffic engineer is prima facie evidence that the speed is not reasonable or prudent and that it is unlawful, unless an increased or reduced speed is necessary for safe operation or in compliance with law.
