Expressway
FRE-EXP-02 Recommended Freeway
Expressway
A high-speed road with partial access control, some at-grade intersections remain, unlike a fully grade-separated Freeway. Out of the Commonway System's detailed design scope.1
Typical at: Rural Suburban Compact
Undeveloped and Urban are edge cases. Core is an unlikely pairing.
Design notes
Expressway sits between full Freeway and Arterial in character, partial rather than complete access control, which is why its realistic density range skews slightly narrower than the full Freeway Default entry.

Default (Freeway) (FRE-DEF-01) (the fully grade-separated form this sits just short of), Default (No Parking, No Direct Property Access) (ART-DEF-01) (the Arterial-scale end of the spectrum this sits between), Signal (INT-SIG-03) (the control type governing the at-grade intersections this pattern still retains)
