About Sustainability

Sustainable transportation practices respect, support and (where possible) regenerate environmental systems, the economy and society over many generations. This requires balancing three components.


Sustainable solutions balance society, the economy and the environment


To ensure the sustainability of the transportation system and the communities it serves, Mn/DOT will:

• Use all resources wisely
• Consider the needs of future generations
• Evaluate a wide range of risks
• Protect and enhance the environment
• Conserve energy and natural resources
• Improve quality of life
• Involve the public in the transportation planning process
• Encourage innovative approaches to the design, operation and maintenance of our facilities.




Operations, Management and Maintenance

Destination Target Field - Sustainability through Innovative Multimodal Solutions:
The decision to locate the Target Field ballpark in downtown Minneapolis provided an opportunity to maximize the potential of existing infrastructure in order to support a fully multi-modal transportation system that provides access not just to the stadium, but also throughout the city and beyond. Through a collaborative effort, transportation systems owned and operated by a variety of jurisdictions and serving different customer bases were linked to form a comprehensive and connected network that includes safe and convenient bike and pedestrian access, improved traffic flow, and transit access via bus, light rail, and commuter rail. Target Field is a stunning, award-winning example of how a broad range of sustainable outcomes can be achieved to provide societal, environmental and economic benefits for both users of the system, the broader community and state as a whole.


Urban Partnership Agreement, MNPASS - Sustainability through Innovative Operations:
Minnesota was awarded $133.3 million through the U.S. Department of Transportation’s Urban Partnership Agreement to improve traffic flow to and from downtown Minneapolis. The UPA program provides commuters with more transportation choices and less traffic congestion on some of the busiest roadways in Minnesota, including Interstate 35W between downtown Minneapolis and Burnsville. The initiative uses a combination of technology, transit, road pricing and telecommuting. It includes a MnPASS toll option that is free for carpoolers and buses. Overall, it provides a cost-effective approach to improving mobility, reducing pollution and enhancing the vitality of the region. 


Tow Plow Technology: The tow plow is a trailer-mounted plow which is pulled and operated from a snowplow. It operates at any angle up to 30 degrees and is capable of plowing snow at normal plowing speeds of 30-40 mph. The 26 foot wide plow gives the operator the ability to move snow efficiently and safely from two lanes of roadway in one pass.

Salt Use Technology: MnDOT’s salt blender mixes road salt with a liquid deicing chemical that makes the salt more effective and less corrosive to vehicles and roadside structures. The blended solution also makes the salt work better at lower temperatures and can reduce overall salt use by 30 percent.  It provides a cost-effective way to protect the environment while maintaining safety and mobility.
