Per 605 ILCS 5/9 113, IDOT requires a permit when working within the right-of-way of an Interstate, U.S. state route, Illinois state route, or state maintained roadway. A permit must be obtained prior to the start of any work and a copy of the approved permit must be at the worksite at all times. There are two types of permits for work within state right-of-way. Below is the process and resources for applying for a Highway Permit - for all non-utility work in right-of-way (municipalities, residential, commercial, agricultural, etc.)
There are two types of permits (utility and highway) for work with state right-of-way.
The Handbook for the Policy on Permits for Access Driveways to State Highways provides a guide to what is allowable when the permit application, OPER 1045, is submitted to our office.
The Quality Standard for Work Zone Traffic Control Devices provides a guide to what is allowable when the permit application is submitted to an IDOT district office. This guide is to help determine what is appropriate when it comes to placing utilities on the right-of-way. The most common requests come from private placement of utilities, municipalities, or utility company requests to do work on state property.
To determine the IDOT district(s) where your project will take place, please view our District Map that identifies which contact information applies your county. Requirements may vary by District, therefore, please contact your district office for specific permit requirements.
To begin the permit process, please complete the Highway Permit Application or a letter of request including a description of proposed work, location map, detailed drawings, traffic studies, traffic control plan and other pertinent information, depending upon the requirements determined by the district office.
Submit two copies of the letter of request along with all required attachments to the District office for approval and processing. District specific forms and information can be found in the Reference tab of this page.
After the request or application has been reviewed the district may require a bond, two copies of the bond must be submitted to the district office. The district will inform you of the required bond value. Inform the district if you have a Blanket Bond to cover work in Illinois.
IDOT will supply the permittee with a highway permit for execution, and also if required, a bond and/or resolution. The time frame for receiving a permit varies depending upon the project. For larger developments, subdivisions or permits with signals/turn lanes, please allow 9 to 14 months from first submission to permit issuance.
Bond Note: Regardless of when work is completed, the permit must be held with an active bond for a period of five years after date of permit issue. If the surety requires a letter from the state verifying a bond may be cancelled, a letter of cancellation must be sent to issuing district referencing the permit number issued.
If a blanket bond was issued, the bond must remain active until five years after the last permit was issued against the blanket bond. To cancel a blanket bond, a letter of cancellation must be sent after five years from the date of last permit issue.
