Hardened Centerlines
Hardened centerlines help prevent drivers from making high-speed, sweeping left turns, which can result in severe or even fatal crashes. The visibility of the hardened centerline also helps to make pedestrians more noticeable, increasing their safety. Hardened centerlines are another tool to encourage slower driving, also known as “traffic calming.”
