The article discusses the challenges of building infrastructure in the US, using the example of the Sepulveda Pass Freeway Expansion Project in Los Angeles, which was completed over a year behind schedule and 55% over budget. The project's difficulties were caused by a combination of factors, including poor planning, bureaucratic delays, and lawsuits from local groups. The article argues that these problems are representative of a broader failure in the US to build and manage large infrastructure projects. This failure is attributed to a range of issues, including a lack of institutional expertise, overly complex regulatory processes, and a culture of NIMBYism.
