Capital Highway Information Management Enterprise System (CHIMES)

Take a look into the future

Are you interested in learning more about what MnDOT has planned for the interstates, and U.S. and state highways in Minnesota?   

CHIMES provides a searchable database of information on upcoming construction projects, including projects by region in the Work Program which is MnDOT’s managed projects in the State Transportation Improvement Program and on the Capital Highway Investment Plan. This database does not include projects that are on county, city and local roads. Users can search for projects by county, region, year, funding source and more. Check out our Quick Reference Guide (PDF) for the new CHIMES application.


Let's use a rest area replacement project on westbound Highway 71 as an example of the kinds of project information users can find on CHIMES:
