Funding a project


MnDOT works closely with the public to develop its long-term vision for investment in Minnesota's transportation system. Project funding decisions are based on whether the project will help move people and goods efficiently and economically. Decisions are also based on the overall transportation needs of the region, safety considerations and funds available.


MnDOT gets transportation funds from motor fuel tax, vehicle sales tax, vehicle registration fees, investment income, the federal government, the state general fund and trunk highway bonds. Currently, the cost to construct one mile of roadway varies from $2-50 million per mile depending on the number of lanes and interchanges constructed and whether the location is urban or rural.
