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 in the MPMS IQ map in the operational layers and determine if it is a signed, numbered highway in 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.

The PennDOT color coding is cross-referenced in the first column of the table for your convenience.

^a Since Pennsylvania combines these two classes, use the criteria from the Freeway page to determine if the road should typed as a freeway or major highway.

^b Some 4-digit State Routes are numbered for legacy or maintenance reasons, but they do not serve as primary thoroughfares for the area and should be classified as  Street .

^c These two categories were changed from  PS  to  Minor  per PA Forum discussion November 2017.
