Road markings are important as they help make the roads safer for pedestrians and drivers as well as ensure that traffic flows smoothly. Over time, these markings can fade and wear out making it difficult for drivers to see. Recently, a double yellow line was added on the curved sections of roadway along Mission St. behind San Rafael High School using a more durable paint called Thermoplastic paint. Thermoplastic is a type of water-based paint that becomes hard and durable when it dries and outlasts traditional paint by many years, especially on newer streets. After only a few days after adding this new line on Mission St., residents have already noticed a reduction in drivers speed through the area.
