"Southbound on the Freeway" consists of thirteen stanzas of two lines each. It is written in free verse, meaning that there is no consistent rhyme scheme or rhythm pattern. The short stanzas give the poem a look of simplicity, suitable for children's poetry because it requires less attention span. After the first stanza, the poem becomes a monologue by the "tourist from Orbitville," giving the tourist's observations of life on earth's freeways. The poem frequently uses the technique of enjambment, placing significant words instead of punctuation at the ends of lines, to draw attention to those words. The monologue is structured in small, simple words, using familiar images and sometimes using slang.
