The bus was northbound, and you come down a straight stretch with a long view when you cross the Klutina River bridge there. A lot of folks under load have their foot in it to make the hill on the north side. If the bus driver was indeed signalling, he 'should've' started about the time s/he was on the bridge deck. If the signal was made after crossing the bridge, it's about 2-300 ft, which is pretty tight in terms of it being 65 mph through there. RV guy should've seen that coming, or it didn't register. I've had a couple instances where southbound travelers have jumped into my northbound lane there to avoid hitting the bus turning right for the hotel. No left turn bay for northbound, nor deceleration lane for southbound; the turn is made straight off the lanes.
