Maintaining Minnesota's Highways

Salt sustainability

Minnesota’s water resources are vital to the people and economy of the State. Even as making roads safe for motorists remains MnDOT’s first concern, all parties involved in winter maintenance must learn to continuously consider the environmental impact and reduce chloride use wherever possible. MnDOT has, and will continue, to take a leadership role in finding ways to meet the public and economic demands for safe winter driving conditions, while optimizing the use of salt.
