Deck Park Tunnel Maintenance of the various electrical/mechanical devices that keep critical life-safety systems working in the tunnel. These systems include ventilation, CO monitoring, fire detection and suppression, as well as a back-up generator to keep these systems fully operational 24/7. This unit also takes an active support role in ensuring the operability of the closed circuit television (CCTV) cameras and lighting within the tunnel.

Interstate Signing

Pavement Management

Pavement Management is an integral part of the process of developing the 5-year construction program by identifying, prioritizing and recommending pavement preservation projects.

The Pavement Management Section runs ADOT’s construction smoothness incentive/disincentive program, which includes testing the finished pavement for smoothness by one-tenth of a mile and calculating either incentive or disincentive for the contractors. The construction smoothness testing is conducted in an accurate, objective and timely manner. In addition, the section is also responsible for evaluating pavement structural and functional condition with annually surveyed data of cracks, potholes, flushing, IRI, faulting, rutting, FWD deflections and friction.  FWD deflections are major pavement structural design inputs for designing pavement rehabilitation projects.

Roadway Lighting

Roadway Lighting maintains approximately 185,000 fixtures as well as the accompanying supports and electrical distribution system. It is also responsible for maintenance of the more than 33,000 fixtures in the Deck Park Tunnel.
