Produced by Encyclopedia Britannica Films in collaboration with M.B. Lagaard of the technological Institute at Northwestern University, the film walks the viewer through the step-by-step process of constructing highways from choosing and surveying the land to laying concrete. Encyclopædia Britannica Films (also named EB Films for short) was the top producer and distributor of educational 16 mm films and later VHS video cassettes for schools and libraries from the 1940s through the 1990s (by which time the internet replaced video as a primary source for educational media).

First step to building highway: Surveyors stand in grassy, hilly area and determine where highway should go (0:52). Smoke fills air as men burn brush, cut down trees in area (1:15). Large chunks of earth, soil move down side of hill as man clears path using bulldozer (1:26). Now that path cleared, 1937 Caterpillar RD8 Track-Type tractor with caterpillar treads pulls along road scraper; Two other tractors push scraper from behind (2:28).
