Default (Freeway)

FRE-DEF-01
Recommended Freeway

Default (Freeway)

A limited-access road with grade-separated interchanges and no direct property access. Freeway is intentionally out of the Commonway System's detailed design scope; no modal hierarchy or speed regulation applies within CS.1

Covers "junk roads," traffic-model incentives to overbuild, and the trillion-dollar cost of designing roads around growth projections that the roads themselves inflate.

Urban is an edge case. Core is an unlikely pairing, marked unlikely rather than edge case on purpose: a limited-access road cutting through a Core-density area is the kind of pattern the Commonway System would flag for retrofit, not treat as a realistic design target.

Design notes

Freeway entries are listed in the Commonway System for completeness and cross-reference, not as a detailed design guide the way Local, Collector, and Arterial patterns are. CS's scope is street and road design; Freeway-scale interchange and alignment design belongs to a different discipline.

Grade-Separated Interchange (INT-GSI-10) (the Intersection pattern governing where this pattern's design guidance resumes), Default (No Parking, No Direct Property Access) (ART-DEF-01) (the Arterial pattern a Freeway interchange typically connects into)
