Beginning June 21st, motorists traveling through South Central and Southwestern Minnesota can expect short term lane closures as Road Weather Information Systems are being installed at different locations throughout the Regional Area.
New stations are being installed in Blue Earth, Faribault sand Martin Counties.
Stations are planned along I-90 near Welcome, I-90 near Wells and also along Highway 30 near Mapleton.
No detours are required for the project. Work will be completed under traffic with flagging operations when lane closures are required for everyone’s safety.
RWIS is an environmental senso station in the field that is used to collect weather data such as atmospheric parameters, pavement conditions and visibility. MnDOT uses the information gathered as well as the camera images for maintenance decision support. The information is also sent to the National Weather Service, as well as Minnesota’s 511 system. There are currently 125 RWIS systems throughout Minnesota, with an additional 36 systems to be added through the state by December 2022.
The project will cost $1.5 million and is scheduled to be complete by mid-September.
