Work Zone Reference Library (WRL)

Attention icon The website will be down from 7 p.m. Friday, Jan. 22 until 1 a.m. Saturday, Jan. 23 for planned maintenance.

Development of the Work Zone Management Service Layer engaged and enabled Iowa DOT staff to envision the future of work zone management.
The WRL is a direct result of this effort and has been created to centralize all of Iowa’s work zone resources and documentation.
