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.

		Highway Systems
		Interstate	Interstate Business, Loop, Spur	US Hwy (incl. some special routes)	US Hwy BUS, SPUR, LOOP	State Route Shielded	State Route Unshielded	Locally Maintained
	Examples	I-80	I-94 Business	US-190	US-460 Business	SR-23 SR-309	SR-2006	Roberts St
F u n c t i o n a l C l a s s	Interstate	Fw	n/a	n/a	n/a	n/a	n/a	n/a
	Other Freeway	n/a	Fw	Fw	Fw	Fw	Fw	Fw
	Other Expressway	n/a	Major	Major	Major	Major	Major	Major
	Other Principal Arterial	n/a	Major	Major	Major	Major	Major	Major

	Minor Collector	n/a	Major	Major	Minor	Minor	PS	PS
	LocalNot Classified	n/a	Major	Major	Minor	Minor	PS	Street

^a Since Pennsylvania combines these two classes, use the criteria from the USA 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 .

A quick reference picture

County or township roads

County (Co) and Township (T) roads need no special designation or road type. Road number info is not needed in the alternate name field.

Ramps

When naming a Ramp to a State Route, use the SR-111 format. PA-111 format should not be used unless it matches exactly what is on the big green sign directing you to the ramp. It is best to reference Google Street View in WME, where available.

Adhere to national standards for Exit ramps and Entrance ramps (on-ramps). Ramp names should use these formats:

Off-ramps:

• Numbered exit: (Exit 16: SR-15 / Scranton)
• Numbered exit with multiple Cities or Routes: (Exit 16: SR-15 N / SR-86 E / Wilkes / Scranton)
• Numbered exit with multiple exits: (Exit 16A-B: SR-15 N / SR-86 E / Scranton)
• Non-numbered exit: (to SR-15 / Scranton)
