Eastern Parkway's "Road Diet" explained.

Stretch Of Eastern Parkway Going On ‘Road Diet’, by Branden Klayko (Broken Sidewalk blog).

A “road diet” is a relatively new technique that enhances the overall functionality of a road. Transportation officials admit is seems a little counter-intuitive to make a better road by removing lanes, but that the idea generates support over time. Officials point out that without a turning lane, traffic is hindered at turning movements and intersections, effectively transforming a four lane road into a two lane road as one lane is blocked.
