Why do road lines on Lower Mainland seem to last?



Regarding letter writer Ken Wells’ reply to fellow letter writer J.M. Birk about disappearing road lines:

Take a look at the many traffic cameras in the Lower Mainland area and see that lines there are very visible on highways and even major intersections and crosswalks, where there is heavy traffic driving over them every day.

Despite the heavy rainfall and the many thousands of drivers on the Lower Mainland, I wonder why their lines seem to last longer.

  1. This question can be answered pretty easily if you think about it for a few seconds. This reminds me of exercises in critical thinking that we used to get in elementary school.

    Vancouver getting rain is a moot point. Rain is not abrasive. Neither is snow, by itself. But after snow, we have road salt, plows, and sand, as well as studded tires, chains, etc. None of which are necessary for rainfall. Abrasion is what wears away the paint, not precipitation or even standard car tires, evidently.

    They don’t have better paint or anything. We just have different conditions. Wasn’t that hard to figure out.

  2. Just wondering if the higher temperatures we see in the interior causes the payment to heat up enough that the water based paint floats off the oil based payment. Certainly seems to soften it up as indicated by the many grooves in and around the Kamloops area.
