I cannot see the second entry in the Map and take me to DetailViewController2.
Is there any way to fix this?

This method:
- (void)mapView:(MKMapView *)mapView annotationView2:(MKAnnotationView *)view
calloutAccessoryControlTapped:(UIControl *)control
will not be called by the map view because it's not named exactly mapView:annotationView:calloutAccessoryControlTapped:.
Naming the method annotationView2 does not automatically associate it with your "second" annotation. Delegate methods must be named exactly as defined by the protocol (MKMapViewDelegate in this case).
You must handle all callout button taps in this one method:
- (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view
calloutAccessoryControlTapped:(UIControl *)control
In there, you can check the annotation's class and handle accordingly (like you are already doing with BridgeAnnotation). For example:
if ([annotation1 isKindOfClass:[BridgeAnnotation class]])
{
//code for Bridge annotation...
}
else
if ([annotation1 isKindOfClass:[SFAnnotation class]])
{
//code for SF annotation...
}
else ...
