Major roads
Pennsylvania follows the general road naming and road type guidelines of the USA. The Functional Classification chart shown below has been modified from the national chart to more closely reflect the roads in Pennsylvania.
Functional Classification reference chart
Use this chart to determine the road type for Pennsylvania roads based on the functional class.
First, find the functional class of the road from the PennDOT Functional Classification county maps and determine if it is a signed, numbered highway in a one of the highway systems.
Follow the column for the road's highway system down to the row for the road's functional class to find the proper road type for that particular road.
A quick reference guide is shown below the chart.

^a When a state highway "SPUR" route is used to connect a state highway with another state highway, a US highway, or an Interstate (i.e., when it is used as a connector/CONN route), use the first state highway column.
^b Also known as Principal Arterial - Interstate.
^c Also known as Principal Arterial - Freeway.
^d Also known as Principal Arterial - Expressway.
^e Also known as Principal Arterial.
^f Also known as Other Arterial.
For example,
- An Interstate Business Loop classified as a Minor Arterial is a Major Highway .
- A US Highway classified as a Minor Arterial is a Major Highway .
- A US Highway Spur route classified as a Minor Arterial is a Minor Highway .
- A State Highway classified as an Other Freeway is a Freeway .
- A State Highway classified as a Collector is a Minor Highway .
- A County Route classified as a Minor Arterial is a Minor Highway .
- A County Route classified as a Collector is a Primary Street
- A locally-maintained road classified as an Other Principal Arterial is a Major Highway .
- A locally-maintained road classified as a Collector is a Primary Street .
