Work Zone Corridor Management in Michigan

Through their “One Corridor Focus” initiative, the Michigan Department of Transportation (MDOT) manages work zones along key corridors as a single unit rather than discrete projects, enabling MDOT to better mitigate travel time delay during construction and maintenance activities. The One Corridor Focus began as a result of lengthy travel delays due to 19 concurrent reconstruction projects on Interstate 94 (I—94) in 2010, a corridor that stretches 250 miles through three MDOT regions. MDOT uses several methods to manage and coordinate road projects along key corridors, including establishing goals and measuring performance during construction, applying consistent work zone standards, and coordinating with stakeholders throughout planning and construction.
