Notice of Intended Action

Proposing rule making related to reference manual for bridge evaluation and providing an opportunity for public comment

The Department of Transportation hereby proposes to amend Chapter 181, "Statewide Standard for Permitting Certain Implements of Husbandry," Iowa Administrative Code.

Legal Authority for Rule Making

This rule making is proposed under the authority provided in Iowa Code section 307.12.

State or Federal Law Implemented

This rule making implements, in whole or in part, Iowa Code section 321.463(4).

Purpose and Summary

This proposed amendment updates subrule 181.1(2) to reference the 2018 edition of the American Association of State Highway and Transportation Officials Manual for Bridge Evaluation. This manual is used by local authorities to evaluate bridges when issuing special permits for certain implements of husbandry with a weight in excess of the weights allowed under Iowa Code chapter 321. The proposed amendment, which updates the edition of the manual, will allow engineers to use the most current information for the evaluation of bridges. The dynamic load allowance sections of the manual, sections 6A.4.4.3 and 6A.4.5.5, referenced in Chapter 181 remain unchanged between manual editions. Other changes in section 6 of the manual are nonsubstantive.

Fiscal Impact

This rule making has no fiscal impact to the State of Iowa.

Jobs Impact

After analysis and review of this rule making, no impact on jobs has been found.


Any person who believes that the person's circumstances meet the statutory criteria for a waiver may petition the Department for a waiver under 761—Chapter 11.

The operating level shall be used for the evaluation of the bridge with only one fence-line feeder, grain cart, tank wagon or tracked implement of husbandry on the bridge at a time.
