The devastation, disconnection, and displacement of highways plowed through cities and neighborhoods is easy to see, but rarely do we quantify the costs in terms of lost wealth, land, residents, and businesses. The damage also could have been much worse, with many planned highways never built or completed. In this article, we examine current and historical data on the impact of one built and one unbuilt highway in Washington, DC.1
I-395/695 (built) and I-95/66/70 extensions (unbuilt)

What was lost in DC? How did these interstates devastate and transform the city, and the people within it? This animation visualizing before and after construction of I-395/695 using historic satellite imagery was produced in partnership with @Segregation_By_Design.
Also, roads are liabilities, not assets, and maintaining or rehabilitating them require significant costs. Highways are the most expensive kind of road to maintain due to their width, material (often concrete), and traffic volumes. Figures vary, but according to a Strong Towns analysis of 2014 FHWA numbers, it can cost upwards of $7.7 million per mile to reconstruct an existing lane of a freeway like this one.
