Case Studies

  • Summaries of agency processes for achieving compliance with the Rule, including how they developed their policy, significant projects definition, TMP guidance, and other Rule components, as well as how they ensure their projects meet the Rule requirements.
  • Coordinating Road Projects - By coordinating projects between transportation agencies, utilities, and other agencies that may need to do construction in the public right-of-way, cities across the country are recognizing benefits and are better able to identify and manage work zone impacts in the early stages of projects.
  • Applying the Work Zone Safety and Mobility Rule to Design-Build Projects - Two case studies on how agencies applied the practices advocated by the Work Zone Safety and Mobility Rule to the somewhat different processes of design-build projects.
  • Missouri DOT I-64 Rehabilitation Project - By using the types of practices emphasized in the Rule, the Missouri DOT successfully completed this full closure rehabilitation project under budget and ahead of schedule.
  • Caltrans I-15 Rehabilitation Project - By using the types of practices emphasized in the Rule, Caltrans successfully completed this project with minimal impact to travelers and the surrounding community.
  • "Holding Down the Fort", by Frank Cippel, article in December 2007 issue of Roads & Bridges, Volume: 45 Number: 12. Provides a good example of how the Pennsylvania DOT used many of the practices that the Rule promotes to successfully undertake a major reconstruction project on the heavily traveled I-279 Fort Pitt Bridge and Tunnel in the city of Pittsburgh.
