The Black Canyon Freeway, Phoenix's first, in the 1960s.

Motoring around metro Phoenix today, it's difficult to comprehend that this was not always a huge agglomeration of real-estate ventures connected by freeways. In fact, Phoenix didn't want them, would have been better off without many of them, yet couldn't avoid their eventual triumph.

In 1950, when Phoenix came in as America's 100th most populous city, it occupied a mere 17 square miles, with a population density of more than 6,200 per square mile, around what you'd find in today's Seattle or Portland. In other words, a real small city: cohesive, walkable, sustainable and scalable. Remnants of the old city exist, but much has been annihilated, not least by the freeways.

By 1960, the city of Phoenix had 439,170 people and nearly 188 square miles. It was a big city of the automobile age, the old streetcars long gone, and federally subsidized sprawl under way. Around this time, the state Highway Department adopted an ambitious freeway plan prepared by Wilbur Smith & Associates, one of the nation's leading highway transportation planning firms. It envisioned much of the system eventually built. The engineers had wanted to build freeways in Phoenix since the late 1940s. One route would have gone directly in front of the Hotel Westward Ho.

But most Phoenicians were horrified. They weren't enamored with the small Black Canyon Freeway, Phoenix's first (it wound around at Durango Street to become the Maricopa Freeway, rammed through powerless barrios).

An urban legend persists that Eugene C. Pulliam single-handedly defeated the freeway plan in the early 1970s. Although the Arizona Republic and Phoenix Gazette were indeed powerful in those days and not afraid to crusade (sometimes for the right reasons, sometimes not), freeways were widely resisted.

Phoenicians then didn't want to become another Los Angeles in this bad way, and they had a chance to avoid the fate. LA had shown (and Robert Moses' New York before it) that freeways didn't solve traffic congestion — they generated it through the phenomenon called induced demand. We didn't want worse smog. We didn't want to lose our views to concrete and the citrus groves to further sprawl. Of particular alarm was the 100-foot-high Papago Freeway Inner Loop planned across central Phoenix, with monstrous "helicoils" discharging traffic onto Third Avenue and Third Street.
