Historic Auto Trails

Special route and bridge designations

Iowa law currently permits special signs to be placed along the Primary Highway System for the purpose of designating a primary highway or bridge as a memorial highway/bridge, scenic trail or historic trail.

Rules 761-131.10 through 131.15(321) in the Iowa Administrative Code establish the requirements and procedures for special sign placement. These rules are administered by the Iowa DOT and the federal Manual on Uniform Traffic Control Devices
