Remove directions from google map api v3

Question

I have a google map using API v3 which gets directions from one location to another. The app works great but the window which gets the directions is an overlay on the map.

Answer 1

None of the above worked for me, this is what I needed:

// Clear past routes
    if (directionsDisplay != null) {
        directionsDisplay.setMap(null);
        directionsDisplay = null;
    }
