USING VIA WAYPOINTS
Via waypoints can be used to drag a trip to or from a specific road, to represent a stop in a general area, to add a stop where there is no address, and in general to quickly customize a trip's route. A common use is to drag your trip off a turnpike or toll road to avoid it.
Rearrange and remove via waypoints the same way other waypoints are rearranged and removed. Via waypoints can also be picked up and moved on the map. Simply click its pin on the map and drag it to where you want to drop it. Your trip will automatically re-route and adjust to the pin's new location.
