Sound Off: When heading north or south on Iowa Street and turning left onto 27th, why is the light a green arrow only? The light is incredibly long, and it seems that the intersection would allow for a green yield when turning left onto 27th from Iowa.
Megan Gilliland, the city’s communications manager, provided this answer: This intersection was upgraded several years ago using Federal-Aid Highway Safety Funding. Data collected at the time showed a higher than normal frequency of north-south, left-turn accidents. The traffic signals were then changed to “left on green arrow only” to aid in reducing accidents at the intersection.
