Median guardrail installed along Hwy 14 starts Sept. 9
Expect temporary lane and shoulder closures between Mankato and Waseca
MANKATO, Minn. – Motorists can expect temporary left lane and shoulder closures along Hwy 14 from Mankato to past Waseca beginning Tuesday, Sept. 9 as crews install high-tension cable median guardrail and shoulder rumble strips.
A total of 10 miles of median guardrail will be installed in the area of the interchanges between Hwy 22 in Mankato and the Waseca/Steele County border. Each interchange will have a mile of guardrail on each side.
High-tension cable median guardrail prevents traffic from crossing the median and hitting on-coming traffic.
Compared to other barriers, high-tension cable guardrail absorbs and dissipates an errant vehicle’s momentum, reducing the severity of the crash, and minimizing occupant injuries. With limited resources, MnDOT is focusing our median guardrail investments in areas with the highest traffic volumes, as well as areas surrounding interchanges. These areas have, historically, had the highest frequency of cross-median crashes. Minnesota crash statistics show that more than 60% of cross median crashes occur within one mile of freeway interchanges.
Shoulder rumble strips are a proven safety strategy. Used to reduce run off the road types of crashes, shoulder rumble strips have been shown to reduce crashes in which motorists run off the right side of the road by 15% to 40%. Also, shoulder rumble strips have been shown to reduce all crashes, overall, by 5% to 20%.
Minnesota traffic safety efforts are components of Toward Zero Deaths (TZD), the state’s primary road safety initiative that is a partnership between the Department of Public Safety, MnDOT, Department of Health, the University of Minnesota and others. A primary vision of the TZD program is to create a safe driving culture in Minnesota in which motorists support a goal of zero road fatalities by practicing and promoting safe and smart driving behavior. TZD focuses on the application of four strategic areas to reduce crashes — education, enforcement, engineering and emergency trauma response.
