Appendix 12: State Examples of Work Zone Coordination
Coordination of Work
Missouri
In 2001, the Missouri DOT began implementing several strategies to reduce the impacts of
construction activities. A statewide work zone coordinator has responsibility for
coordinating lane closures across district boundaries and across the state, considering the
statewide impact of work zones on traffic, and ensuring that the statewide traffic effects of
major sporting events, the state fair and other special activities are considered when
planning work zones. Each of MoDOT’s ten districts also has a work zone coordinator to
coordinate activities within that district. The responsibilities of the district-level work zone
coordinator include:

Scheduling lane closures during off-peak and/or nighttime hours when possible, when
traffic volumes exceed 75 to 80 percent of the open-lane capacity

Scheduling work on multiple projects on the same route

Scheduling multiple tasks in a single work zone, rather than scheduling multiple lane
closures in the same area. Proper coordination can avoid scheduling work/utility
activities on parallel routes at the same time.

Working with project development to ensure that working days for projects requiring
lane closures will be reduced, when possible.

Notifying the statewide work zone coordinator before any lanes are closed on the
National Highway System

Review commercial and utility or permit projects to reduce their negative effects.
In order to better coordinate work zone activities statewide, Missouri is also planning to
develop an online database identifying major events and to develop one electronic request
form for all work zone activities.
