Guide to Establishing Speed Limits in Highway Work Zones

The purpose of this document is to provide a uniform guideline for the proper application of speed limits in street and highway work zones. This booklet outlines the guidelines, proper layouts and procedures for implementing work zone speed limits primarily for use by Mn/DOT personnel. Although it is usually desirable to provide all traffic controls as shown in the layouts, situations arise where this becomes impractical. Engineering judgment may dictate modifications to the typical layouts. When modifications are made, factors such as traffic volume, speed, sight distance, type of work, etc. must be considered.
