This document describes the various methods of traffic management used in Minnesota.

The following document is obsolete, and was created in conjunction with Standard Plan sheets for bent-pipe monotube overhead sign supports, for the sole purpose of selecting main members from a limited number of pre-engineered sizes under a controlled set of geometric criteria. Its basis of design is the 1994 edition of the AASHTO Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals. Minnesota's current design document for Sign Supports is the 2001 edition of the above-mentioned AASHTO publication. The 2001 edition requires a fatigue analysis for all cantilevered sign and signal support structures. The attached document was prepared prior to that requirement. Minnesota Department of Transportation does not endorse or warrant the use of this document or the Standard Plan sheets addressed in this document to produce a sign support structure that will be compliant with current specifications. Any such structure must be designed by a qualified engineer, and must address design, constructability, and maintenance deficiencies that could result from the use of this document.
