Iowa Work Zone Safety Guidelines for Utilities

This handbook generally represents minimum requirements for typical situations. It is not intended as a substitute for engineering judgment and may need to be altered to fit the conditions of a particular site. All traffic control used must be in compliance with the Manual on Uniform Traffic Control Devices (MUTCD), which contains information in addition to what is in this guide. For work zones on primary or interstate roadways, please consult the Iowa DOT area maintenance supervisor. Proper traffic control must be used when utility operations, or other types of road or street construction, may interfere with the movement of traffic. Appropriate measures must be taken to protect drivers, workers and pedestrians.
