    MIDTOWN GREENWAY // MINNEAPOLISThis 5.5-mile, urban, paved, bike and pedestrian trail connects across midtown Minneapolis between the Mississippi River and the Minneapolis Chain of Lakes. It is sited in a former railroad right-of-way.

    5.5 MI. LONG30-160 WIDE, 90 TYP.

    EDGE AND GRADE SEPARATES THE CORRIDOR FROM THE GRIDThe 5.5-mile corridor is primarily grade-separated from the street grid. The majority is below grade in a trench with walls ranging from gentle to steep slopes to retaining walls. Portions at each end of the corridor are at grade or above grade on a levee. The trail is accessed at grade or via stairs or ramps.

  • LANDSCAPE / VOLUNTEERISMLandscaping along the greenway is primarily installed and maintained by volunteers. An Adopt-a-Greenway program is in place to encourage community involvement in maintenance of the trail. Gardens along the trail demonstrate native plants and on-site water management, including rain gardens.

    BIKE CENTERA bike center is located at grade along the corridor. Services include parking by day or contract, parts and repairs (DIY or as service), rentals, bathrooms, showers, and a coffee shop.

    LAND USEThe Midtown Greenway Land Use Development Plan was approved in 2007. The study area generally ex-tends one block from the corridor and includes land use, zoning, and public realm and design guidelines.

    ART / HISTORY The trail is conceived of as a space for both permanent and temporary artwork--includ-ing this graffiti wall--as well as performance art. Signs along the trail describe the history of the trail, the preceding railroad, and various points of interest along the way.

    FUTURE: MULTI-MODAL WITH LIGHT RAILThe county governments long-term plans for the greenway include its use a light rail corridor. Citizens, including the Greenway Coalition, support this use.
