UNDATED -- When the snow melts, trash and litter are left behind in Minnesota's highway ditches. That's when volunteer organizations step in and clean the right-of-way as part of Minnesota's Adopt-a-Highway program.

Program Administrator Ernest Lloyd says it's become a very popular program since its inception in 1990.  He says many groups sign up year after year.  He says they take great pride in helping keep their communities clean and beautiful.

Lloyd says volunteers keep more than 10,400 miles of Minnesota's highways clear of litter. He says it saves the state of Minnesota more than $5-million a year and allows MnDOT crews to focus on things like potholes and other repairs.

MnDOT asks groups to make a two-year commitment to the program and ask that you clean your stretch stretch of highway at least twice per year.
