Construction Projects

General information on our construction projects, plus material on contractor bidding, prequalification, and more.

The Ohio Department of Transportation constructs and maintains the state transportation system. Generally, we are responsible for interstate routes, as well as state and federal routes outside of municipalities.

The state of Ohio is a "home rule" state, which means that municipalities are responsible for all roadways within their own municipal limits – including roads that are part of the state or federal system. For any concerns regarding roadways within municipalities, please contact the municipality responsible.

Below are some resources related to the construction of the state's transportation infrastructure. For general information or questions about active or upcoming constructions projects, please visit our Projects library or use our contact form.
