Oliver says US dams are too old: “Like most Botox recipients and competitive cloggers, the age of the average dam is 52 years old, and probably has something deeply broken inside of it.” Bridges are falling apart: In 2014, the US Department of Transportation reported that 61,365 bridges in the US were structurally deficient, and roads nicked with potholes and cracks are not being repaved. Oliver reports that the US Highway Trust Fund is the single largest source of highway infrastructure funding, and it’s set to go bankrupt this summer unless Congress saves it.
