AUTOMATED BRIDGE DECK ANTI- AND DEICING SYSTEM

This Innovations Deserving Exploratory Analysis (IDEA) report addresses the design, installation, and testing of a fixed system, installed permanently on a bridge, so that the bridge deck may be anti- or deiced automatically without calling out traditional snow and ice control crews and equipment. This "Automated Bridge Deck Anti- and Deicing System" uses accepted liquid freezing point depressants, such as NaCl brine or liquid MgCl2, and traditional spray application techniques, coupled with a modern roadway weather information system (RWIS) and novel data communication and process control to perform the task. The prototype system was installed on the Interstate I-215 overpass/interchange at 6200 South Street in metropolitan Salt Lake City. This curved bridge deck has six lanes, in total, and is over 400 ft (122 m) in length. This project verified that fixed bridge deck snow and ice control material broadcast systems can significantly and cost effectively enhance motorist safety during icing conditions relative to the present over-the-road methods of operation.
