What’s Up With That? reports that Los Angeles is spending $40,000 per mile to paint streets white in order to fight global warming.
First, tires are abrasive. How long do they think the paint will last?
Two, most highway-grade paint is petrochemical-based. Did they consider the carbon footprint of the project from manufacturing the paint all the way through to application and maintenance?
Oh, one more thing … there are 6,700 miles of roadways in LA. Doing the whole network would cost something north of a quarter-of-a-billion bucks. What if that money were spent on something like schools or housing for the homeless?
UPDATE—The Daily Mail reports that the product being smeared on LA’s streets is CoolSeal. (H/T, Stephen Green). According to the manufacturer’s website, it is a water-based asphalt sealant designed “for lightly trafficked areas,” so it’s not exactly highway-grade. They may need to find something else to use on roads such as Century Boulevard.
UPDATE 2—Won’t this make the white lines between lanes and defining crosswalks hard to see?
