The Iowa DOT values accessibility of our transportation system for all customers. This includes the need to have sidewalks and driveways next to state highways accessible to people with disabilities. The Americans with Disabilities Act of 1990 (ADA) requires each public entity to plan and construct sidewalks that are accessible.

As part of the ADA mandate, government entities must plan and update pedestrian access or risk losing federal funding. The Iowa DOT shares responsibility with cities for state highways and supports smaller communities (under 5,000 residents) that may lack resources. Larger cities typically fund these projects through their own plans.

ADA Transition Plan

In February 2012, the Iowa DOT adopted a plan to address ADA compliance along state highways in smaller cities. The purpose of the plan is to identify the steps the Iowa DOT will take to achieve ADA compliance for sidewalks and multiuse paths. All Iowa DOT-designed projects will be built using state funds.

Sidewalks and paths must meet guidelines established by the United States Access Board.

The Iowa DOT’s Approach to Meeting Federal Standards

Public Right-of-Way Accessibility Guideline (PROWAG)

  • The Iowa DOT, working with staff from the Statewide Urban Design and Specifications (SUDAS) and Federal Highway Administration, developed design guidance that can be used by all government agencies in Iowa. Local groups may choose to use their own standards, but those would require review and approval by the FHWA and/or the United States Department of Justice. The public right-of-way accessibility guidelines (Chapter 12) developed by the Iowa DOT and SUDAS have been approved by the FHWA as this section was developed in accordance with federal regulations
    (23 CFR § 652 and 28 CFR § 35).
  • To review the information the Iowa DOT follows, see Chapter 12 of the Design Manual.
  • Additional information on the PROWAG document.

Federal Law and Consequences

  • The Code of Federal Regulations (28 CFR § 35.150) requires the Iowa DOT to have a transition plan for all ADA features within our jurisdiction and within the public rights-of-way. Consequences of not developing or following the plan could result in the Iowa DOT losing a significant percentage of federal money received (28 CFR § 35).
