New type of traffic interchange in Phoenix will have you driving on the left

PHOENIX (3 TV / CBS 5) Valley drivers will encounter a new kind of traffic interchange in the next few months. Two new diverging diamond interchanges will be opening along the new South Mountain portion of the Loop 202. “As a driver, I know it’s going to be a little bit concerning,” said ADOT spokesman Tom Herrmann. That’s because these interchanges have you driving on the left.
