How about Arlington puts a "Yield Ahead" or "Rotary Ahead" on their part of the downhill stretch leading into this rotary. So often people race down the hill and cut off traffic already in the rotary, seemingly on the basis of "I've got the right of way because I'm moving fastest"

The rotary and approaches need to be redesigned to slow the traffic. Drivers cresting the hill on the bridge heading westbound can get to and into the rotary while those waiting patiently on the southbound approach think it's their turn to go. Roundabouts work when everyone has to slow to enter.

DCR does not own roads. It is a state highway. State Police should be notified. This was opened SIX years ago. I don;t think it is on their to do list !

The DCR placed large "ROTARY >>>>" signs on both sides (Arlington & Medford) so I think this shoudl have been closed (and am closing it)
