Traffic is about to change in South Haven. Starting next week, the city of South Haven will have “No Left Turn” signs posted along westbound Phoenix Street from Broadway to Water Street. They’re being given a 90 day trial to see if they improve traffic flow. Phoenix Street is the main street running through South Haven’s downtown. During the summer, a long line of traffic headed to the beach often causes congestion as drivers try to make left turns. It’s hoped the No Left Turn signs might help. The South Haven City Council will review the results at the end of the 90 day trial.
