Estrella itself isn't so congested, but you'll get a big headache of sorts upon reaching Guadalupe before the bridge. You can escape that by going via JP Rizal then Trace. If JP Rizal is congested, I suggest you take the road parallel to it (I can't remember the name, but it is relatively easy to pass even in rush hour) then enter JP Rizal at around the Shell area. It'll be a short hop then going to Trace.
