As you can see in the video, you not only have to worry about oncoming traffic when making a left on Southwestern Boulevard here, but have you to check your rear view mirror as well. That's about to change.
Think of all the times you've headed down Broadway through Lancaster and Alden to Darien Lake for a concert. Or when you've used Southwestern Boulevard to get to the Ralph Wilson Stadium for a Buffalo Bills game. What do those two roads have in common?
They're both designated U-S Route 20.
