Traffic Lights

Motorists traveling on Hwy. 169 through and around St. Peter will soon see improved traffic signal operations.

Over the past few weeks, the Minnesota Department of Transportation has been upgrading traffic signal hardware and testing signal timing plans for all five traffic signals. Starting on June 14, the final updated signal timing plans will be implemented.

The adjustments will provide improved traffic operations on Hwy. 169 and allow for advanced performance monitoring through a central traffic management system. Motorists can expect to hit more green lights when traveling the speed limit, but may experience a bit more delay in crossing or turning onto Hwy. 169. Pedestrian signal timing was also checked to ensure adequate walk/don’t walk crossing times.

When making a left turn at certain intersections, drivers may find that the left turn arrow appears at a different time in the cycle.

“Motorists will need to pay closer attention at the signals, as the timing and sequencing may not be what they are used to,” explained Scott Thompson, District Traffic Engineer. These changes were made to improve how the traffic signals operate together as a system.

Motorists will benefit from reduced delays, stops, 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.
