In 2005, MDT implemented a rockfall management system for use on the Department’s state-maintained roadways. The system selected and customized for MDT was the Rockfall Hazard Rating System (RHRS) that was developed as a result of the Rockfall Hazard Classification and Mitigation System research project. Another research project starting July 2015, will evaluate the existing system and update it as necessary to a more effective asset management system that can be used as a planning tool to guide MDT on rockfall mitigation projects.
