Public Works Service Bureau

SUDAS staff received a research grant from the Iowa Highway Research Board to conduct a study to determine if it is feasible to create a Public Works Service Bureau in the State of Iowa. We envision this Public Works Service Bureau to be an organization that provides public works staff from cities of all sizes across Iowa a direct way to communicate among themselves and other agencies, such as the Iowa DOT. It could also provide a location to input information for a central clearinghouse on any number of topics, which could then be used to provide statewide data to improve decision making and efficiency of operations. The final report of the feasibility study can be found here.

Temporary Traffic Control

SUDAS staff developed an updated Temporary Traffic Control Handbook through an Iowa Highway Research Board project. If you would like to request a copy, please complete this form. Click here for an electronic version of the handbook.
