This is good news. Should save some time. Get in your cars and drive!
The U-turn ramp located at the Allston-Brighton toll plaza opened to drivers with Fast Lane and E-Z Pass transponders on Sunday.
Two-axle passenger vehicles with FAST LANE will be charged $2 to use the ramp. E-Z Pass customers will pay $2.50. Taxis and two-axle trucks are charged $2.50, and three-axle buses $4 — the same price they would pay if they went through Exit 20 tolls twice while turning around.
The way it is now, if you are coming from Logan Airport and want to get to Back Bay or the South End, you have to get off in South Boston (actually, the Seaport District) and make your way around the city, or take the exit to Rt 93 South and cross five lanes of traffic to get off at Mass Ave, in the South End.
With the new turnaround, you can drive to the Allston-Brighton tolls and then reverse direction, back into the city, exiting at Prudential. (I guess you could have always have exited there and taken Storrow Drive back in, but I never thought of that before.)
