During evening rush hour(s), when traveling north on Wiehle, traffic backs up to the exit/on ramp of the Toll Road because the light at the intersection of Isaac Newton Sq & Wiehle is not in sync with the light at Wiehle & Sunset Hills. Traffic cannot move throught the Sunset Hills intersection going north, and cars can sit through two lights there. The light at Isaac Newton Sq turns red when the Sunset Hills intersection light is green. The light at the Isaac Newton Sq intersectin was just replaced about 3-4 weeks ago, and I think it needs to be reprogrammed to allow traffice to move through the Sunset Hills intersection. It is a mess at rush hour going north on Wiehle.
