Hwy 22 Mankato traffic signal timing updates – expect changes beginning Nov. 27

MANKATO, Minn. – Motorists traveling in Mankato will soon see improved traffic signal operations along Highway 22, according to the Minnesota Department of Transportation. MnDOT has been developing updated signal timing plans for all seven traffic signals. Starting on Monday, Nov. 27, the updated signal timing plans will be implemented.

The updated timing plans account for changes in traffic volumes and patterns that have developed since the traffic signals along Highway 22 in Mankato were last coordinated in 2019.  Motorists can expect to encounter more green lights when traveling the speed limit but may experience a bit more delay in crossing or turning onto Highway 22. 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.
