Using National Functional Classifications (NFC) Maps

Any National Functional Classification (NFC) may be rural or urban. Urban NFC's are along or inside the Adjusted Census Urban Boundary (ACUB).

  • Roads shown as thick, blue, purple, red, green, orange and urban yellow lines are federal-aid highways.
  • Rural roads shown as thick, yellow lines (rural minor collectors) have limited federal-aid eligibility for STP funds per current federal law (FAST-Act).
  • Roads shown as thin, black lines (local roads) are not eligible for STP federal-aid.
  • Roads shown as thin, gray lines are not under the jurisdiction of any public road agency, these roads are not eligible for federal-aid.

Every attempt is made to show public agency roads. However, only agency certified Act-51 maps are official sources for this information.

STP funds may be used on any federal-aid highway, following the project selection process established by federal legislation.

The dashed future NFC routes shown in the legend refer to un-built routes. If an un-built route is entered into the STIP with a local funding match and the function of the un-built route is expected to function as a federal-aid highway, then a proposal to apply for a federal-aid functional classification can be made in cooperation with MDOT to be sent to FWHA for approval. Program-specific information can be found on the Grant Programs webpage
