Signing Plan

Purpose

Traffic signs are devices that regulate the flow of traffic, warn users of upcoming changes or hazards, and guide users and keep them safe. A signing plan lays out the best way to arrange these signs.

When to use this subject

Use this guidance on most construction projects. Typically the signs are impacted by a change in geometrics or the sign bases are impacted with a change in grading.

For specific process information, see the other guidance page and/or contact the individual on the contacts page.

How this subject fits into the overall project development process

Scoping should always include a discussion with the District Signing Unit. All freeway and complex intersections require signing to be considered in the layout development and may require a signing layout along with a geometric layout. Borings are required for all overhead sign structure footings as well as needing current clearance height of the structure over the roadway. When the signing plan is complete, include it in the main construction plan for project turn in. Prepare the signing plan during final design.  When it is complete, include it in the main construction plan for project turn in.
