State, U.S., and certain city/county roads identified on the map below are valid routes except for restrictions listed on the bridge embargo, pavement restriction, road conditions (511ia.org), and vertical clearance maps. Not valid on the interstate system.

Non-paved Farm-to-Market and Non-Farm-to-Market Secondary Roads

Effective July 1, 2025, all non-paved Farm-to-Market and non-Farm-to-Market secondary roads will be valid under this permit. However, due to the volume of these routes and to ensure public safety, additional time is needed to verify that non-exempted routes are safe for the loads specified by the law. These roads will retain their June 30, 2025 designations for one month while exemption requests are gathered and reviewed. Unless exempted, all such roads will become valid by the end of July.
