The rise of the automobile as the most common form of transportation after World War II made building highways a top post-war priority. As cities were connected by larger highways with higher capacities, and the suburbs blossomed on the edges of urban areas, the need for high-capacity corridors through major cities became more acute. Before 1950, most highways were routed on city streets in urban areas, streets that often were designed for a fraction of the traffic.
With Eisenhower’s Interstate Highway plan, the die was cast. Urban planners such as Robert Moses saw their visions of grade-separated thoroughfares to carry traffic through cities quickly come to life. The promise of living in the idyllic suburbs and working in the city seemed to justify the cost. Unfortunately, as the first wave of construction tore through cities, it became apparent there was another cost. Historic neighborhoods, some over a hundred years old, were suddenly torn apart, divided by six to ten lanes of speeding traffic. It is hard to imagine how different life in these neighborhoods was before the freeways were built. Here are five examples of Portland neighborhoods that fell victim to the all-mighty automobile.
