District 6 Mask

The District 5 mask layer allows a focal view of the geographic boundary of Idaho Transportation Department's (ITD) District 5, and removes neighboring districts feature visibility to improve legibility. The polygon is identified by a district ID number and provides a clean visual for organizing transportation operations used to define the operational zones for highway maintenance activities, resource allocation, and administrative oversight. District Boundaries and subsequently district masks are subject to change at the discretion of the Idaho Transportation Board. This content item is a sub-layer of the Cartographic Masks authoritative feature layer.
