title: Hide highway numbers without removing the directions
body: <p>I am trying to style the map which shows the directions of all roads without the road numbers on them.</p>
  
  <pre><code>{
      featureType: "road.highway",
      elementType: "labels.icon",
      stylers: [
          {color:"#979897"},
      { lightness: 50 },
      { visibility: "off" }
      ]
  },
  </code></pre>
  
  <p>But this removes the directions on the road as well the numbers.I want to show only the directions without the highway numbers.</p>
