HAH! I took this exit twice last weekend! Really terrifying merge during Saturday afternoon traffic, but it was easy on Sunday morning (as I breathed a sigh of relief that I was leaving Pittsburgh and wouldn't have to do it again). Reminds me of a similar on-ramp onto the BQE in Brooklyn, which is equally if not more congested:
