Work Zone Bulletins

Work Zone Bulletins clarify, supplement or modify standards in the Department's 2008 Traffic Accommodation in Work Zones Manual. The intent of these bulletins is to improve safety by presenting new traffic control devices, measures and strategies for work zones. As some new traffic control devices add a higher cost to the traffic accommodation strategy, they may need to be included in the contract's special provisions.
