The right turn only lane causes near-accidents (and actual accidents) every day. People don't understand that the turn lane ends before the exit for 495, so they move over and then find themselves trying to merge back into traffic to take the exit. Worse yet, many people don't notice that it's a right turn only lane (onto Magarity), and just keep moving forward, leaving people in the middle lane to scramble to accommodate them lest their cars suffer damage. This is a terrible intersection and needs to be fixed -- I'd suggest extending the right turn only lane beyond the intersection to the 495 exit, because that's what people expect. As it stands, you have a lane shift and a lane ending, and it's unnatural and counterintuitive.
