title: Using Google Maps to highlight whole roads
body: <p>I've been looking everywhere for a way to highlight a whole roads on a Google Map via the API.</p>
  
  <p>As in, I want some roads to be highlighted red, others green etc. </p>
  
  <p>Is this possible? I can't seem to find anywhere that mentions it. I'd like it to look like how it does when you view the traffic data on a map via maps.google.com. </p>
  
  <p>Thanks in advance.</p>
