Motorists on Highway 169 in St. Peter today and tomorrow (May 21-22) may notice that the traffic signals are not behaving as usual.


Crews from the Minnesota Department of Transportation are out testing and fine-tuning for updated traffic signal plans for all five traffic signals along Highway 169 in St. Peter for improved traffic flow in the near future.


Over the next few weeks, motorists may see communication hardware installed and additional adjustments as the traffic signals will be integrated into a central traffic management system for advanced performance monitoring.


Once the new system is completed, motorists will benefit from reduced delays, fuel usage and wear and tear on their vehicles.  Nationally, updating traffic signal timing has been shown to reduce traffic delay by 15-40 percent, reduce travel times by up to 25 percent, and has a benefit to cost ratio that can exceed 50:1.
