You can get a value with somethings like routes.get(0).get(0).get("yourKey") but can you be more precise about the structure of this combination of collections ?
Oh ok, so if you do routes.get(0).get(0) you get a HashMap<String,String> that I'll call "latlong". latlong.get("lat") will return the latitude and latlong.get("lng") the longitude
