I have learned that you can get in, and STAY in, the center lane on Storrow Drive, from Kenmore all the way onto the I93 North ramp. The signs say move here and there, but you don’t actually have to move at all. The far left lane works two. Pick one, and stay with it.
Also, the center lane works all the way from I93 South to Kenmore. Just stay in it.
