I'm building a map that allows draw route from two location by using Bing Maps. However, I have a overlay on the route (for example: police, traffic jam...). So, I want to draw other route for two locations. Anyone can help me! Thanks for your time!

Code to draw a route from two locations:

private void RouteServiceTest(Location from, Location to)
{
            var request = new RouteRequest
            {
                Options = new RouteOptions { RoutePathType = RoutePathType.Points },
                ExecutionOptions = new ExecutionOptions { SuppressFaults = true }
            };
            
            request.Waypoints = new ObservableCollection<Waypoint>
                                  {new Waypoint{ Location = from},
                                   new Waypoint {Location = to}
                                  };
            var client = new RouteServiceClient("BasicHttpBinding_IRouteService");
            client.CalculateRouteCompleted +=
                (o, args) =>
                {
                    if (args.Error == null)
                    {
                        var line = new MapPolyline
                        {
                            Locations = new LocationCollection(),
                            Stroke = (Brush)Application.Current.Resources["PhoneAccentBrush"],
                            StrokeThickness = 4

                        };
                        foreach (var point in args.Result.Result.RoutePath.Points)
                        {
                            line.Locations.Add(point);
                        }
                        map1.Children.Add(line);
                        map1.SetView(LocationRect.CreateLocationRect(line.Locations));
                        //mapMain.ZoomLevel = 2;
                    }
                };
            var pushpinMicrosft = new Microsoft.Phone.Controls.Maps.Pushpin
            {
                Content = "Microsoft",
                Location = from,
                Background = (Brush)Application.Current.Resources["PhoneAccentBrush"]
            };
            var pushpinGoogle = new Microsoft.Phone.Controls.Maps.Pushpin
            {
                Content = "Google",
                Location = to,
                Background = (Brush)Application.Current.Resources["PhoneAccentBrush"]
            };
            map1.Children.Add(pushpinMicrosft);
            map1.Children.Add(pushpinGoogle);
            map1.CredentialsProvider.GetCredentials(credentials =>
            {
                request.Credentials = credentials;
                client.CalculateRouteAsync(request);
            });
