Beginning July 1, grass on the sides of state routes will be mowed once a year instead of twice, and interstates will be cropped three times annually rather than four.
DOT spokesman Mark McKinnon said the steps are expected to save almost $11 million over the next year.
McKinnon said the exception to the new mowing schedule will be when there is a potential hazard, such as grass growing too tall and blocking a road sign.
He says there also will be less pickup of trash along the roads, except for things that could be dangerous to vehicles.
McKinnon says the DOT does not expect the cuts to be permanent.
