True, but I think there's some budgetary gimmickry going on in the declaration of short strecthes of freeway. The oddest bit I know is well north of San Fracisco, approaching Willits from the south. This four-lane divided road is declared a freeway as soon as one is past a particular cross road; almost immediately, as it seems, the signs warn that the freeway is about to end. Even weirder: the official End Freeway sign comes after the road has narrowed to two lanes! Surely nuttiness like a one-mile freeway that ends as a two-lane road has to have an economic basis. Actually, it has more to do with roadway standards than with an economic basis . A freeway section reflects a certain specification of roadway, usually meaning 2 (or more) lanes in each direction, barrier- or median- separated, usually (but not always) with emergency shoulders, and *NO* cross-streets, intersections, or driveways. What exactly constitutes a freeway section differs from state to state, although most are similar, and generally reflect something close to Interstate Highway standards. Also, to whomever asked how many drawbridges there are on the Interstate system, the answer is 11. One is currently being replaced with a fixed span (I-95 in Jacksonville, FL), while two others have fixed span replacements proposed (I-95/495 Woodrow Wilson Bridge near DC, and I-280 in Toledo, OH).
