Welcome to Illinois Department of Transportation Bridge Information website. Our goal is to offer bridge inspection and inventory information to the public.
Informational notes:
- You can locate bridges by County, Interstates, U.S. Highways, IL Highways, address, and structure number.
- You can use the map to view structures in a particular area.
- Information included is from IDOT's Structure Information Management System.
- IDOT will update the structure information nightly. Keep in mind that data could change as the information is updated.
- For Official Vertical Clearance information on Marked Routes, go to: http://www.dot.il.gov/road/markedverticalclearances.pdf. Marked Routes are those roadways designated by an Interstate, US, or Illinois signage
- For Official Vertical Clearance information Unmarked Routes, go to: http://www.dot.il.gov/road/unmarkedverticalclearances.pdf . Unmarked Routes are those roadways that are not designated by Interstate, US, or Illinois signage.
- Structure Information and Procedure (SIP) manual: http://www.dot.il.gov/isis/pdf/ISIS_Manual_Internet.pdf
- The ‘Detailed’ report available for each bridge could take several seconds to load as it contains an extensive number of data elements. Please be patient.
- Bridge locations as shown on the map depict the beginning of the structure. If you have any questions or need a detailed explanation, please contact us.
This is part of IDOT's effort to provide ongoing information to the public. We appreciate your interest in bridge information.
